I don't use any of these type of LLM tools which basically amount to just a prompt you leave in place. They make it harder to refine my prompts and keep track of what is causing what in the outputs. I write very precise prompts every time.

Also, I try not work out a problem over the course of several prompts back and forth. The first response is always the best and I try to one shot it every time. If I don't get what I want, I adjust the prompt and try again.

  • corry 16 hours ago

    Strong agree. For every time that I'd get a better answer if the LLM had a bit more context on me (that I didn't think to provide, but it 'knew') there seems to be a multiple of that where the 'memory' was either actually confounding or possibly confounding the best response.

    I'm sure OpenAI and Antropic look at the data, and I'm sure it says that for new / unsophisticated users who don't know how to prompt, that this is a handy crutch (even if it's bad here and there) to make sure they get SOMETHING useable.

    But for the HN crowd in particular, I think most of us have a feeling like making the blackbox even more black -- i.e. even more inscrutable in terms of how it operates and what inputs it's using -- isn't something to celebrate or want.

    • brookst 12 hours ago

      I'm pretty deep in this stuff and I find memory super useful.

      For instance, I can ask "what windshield wipers should I buy" and Claude (and ChatGPT and others) will remember where I live, what winter's like, the make, model, and year of my car, and give me a part number.

      Sure, there's more control in re-typing those details every single time. But there is also value in not having to.

      • brulard 12 hours ago

        I would say these are two distinct use cases - one is the assistant that remembers my preferences. The other use case is the clean intelligent blackbox that knows nothing about previous sessions and I can manage the context in fine detail. Both are useful, but for very different problems.

        • helloplanets 8 hours ago

          I'd imagine 99% of ChatGPT users see the app as the former. And then the rest know how to turn the memory off manually.

          Either way, I think memory can be especially sneakily bad when trying to get creative outputs. If I have had multiple separate chats about a theme I'm exploring, I definitely don't want the model to have any sort of summary from those in context if I want a new angle on the whole thing. The opposite: I'd rather have 'random' topics only tangentially related, in order to add some sort of entropy in the outout.

      • hereonout2 2 hours ago

        I've found this memory across chats quite useful on a practical level too, but it also has added to the feeling of developing an ongoing personal relationship with the LLM.

        Not only does the model (chat gpt) know about my job, tech interests etc and tie chats together using that info.

        But also I have noticed the "tone" of the conversation seems to mimick my own style some what - in a slightly OTT way. For example Chat GPT wil now often call me "mate" or reply often with terms like "Yes mate!".

        This is not far off how my own close friends might talk to me, it definitely feels like it's adapted to my own conversational style.

      • abustamam 2 hours ago

        I mostly find it useful as well, until it starts hallucinating memories, or using memories in an incorrect context. It may have been my fault for not managing its memories correctly but I don't expect the average non power user will be doing that.

      Both of you are missing a lot of use cases. Outside of HN, not everyone uses an LLM for programming. A lot of these people use it as a diary/journal that talks back or as a Walmart therapist.

      • gordon_freeman 9 hours ago

        Walmart therapist?

        • chaostheory 8 hours ago

          People use LLMs as their therapist because they’re either unwilling to see or unable to afford a human one. Based on anecdotal Reddit comments, some people have even mentioned that an LLM was more “compassionate” than a human therapist.

          Due to economics, being able to see a human therapist in person for more than 15 minutes at a time has now become a luxury.

          Imo this is dangerous, given the memory features that both Claude and ChatGPT have. Of course, most medical data is already online but at least there are medical privacy laws for some countries.

    • awesome_dude 14 hours ago

      If I find that previous prompts are polluting the responses I tell Claude to "Forget everything so far"

      BUT I do like that Claude builds on previous discussions, more than once the built up context has allowed Claude to improve its responses (eg. [Actual response] "Because you have previously expressed a preference for SOLID and Hexagonal programming I would suggest that you do X" which was exactly what I wanted)

      • logicallee 12 hours ago

        it can't really "forget everything so far" just because you ask it to. everything so far would still be part of the context. you need a new chat with memory turned off if you want a fresh context.

            LLMs literally can’t forget. If it’s in the context window, it is known regardless of what you put in the context next.

              Given the two very VERY dumb responses, and multiple people down voting, I am reminded how thankful I am that AI is around now, because it understood what you clearly don't.

              I didn't expect it to delete the internet, the world, the universe, or anything, it didn't read my request as an instruction to do so... yet you and that other imbecile seem to think that that's what was meant... even after me saying it was doing as I wanted.

              • baq 4 hours ago

                I think you completely misunderstood me, actually. I explicitly say if it works, great, no sarcasm. LLMs are finicky beasts. Just keep in mind they don’t really forget anything, if you tell it to forget, the things you told it before are still taken into the matrix multiplication mincers and influence outputs just the same. Any forgetting is pretend in that your ‘please forget’ is mixed in after.

                But back to scheduled programming: if it works, great. This is prompt engineering, not magic, not humans, just tools. It pays to know how they work, though.

              • dns_snek 4 hours ago

                > I am reminded how thankful I am that AI is around now, because it understood what you clearly don't.

                We understand what you're saying just fine but what you're saying is simply wrong as a matter of technical fact. All of that context still exists and still degrades the output even if the model has fooled you into thinking that it doesn't. Therefore recommending it as an alternative to actually clearing the context is bad advice.

                It's similar to how a model can be given a secret password and instructed not to reveal it to anyone under any circumstances. It's going to reject naive attempts at first, but it's always going to reveal it eventually.

          • mediaman 4 hours ago

            He is telling you how it mechanically works. Your comment about it “understanding what that means” because it is an NLP seems bizarre, but maybe you mean it in some other way.

            Are you proposing that the attention input context is gone, or that the attention mechanism’s context cost is computationally negated in some way, simply because the system processes natural language? Having the attention mechanism selectively isolate context on command would be an important technical discovery.

            • typpilol 3 hours ago

      > For every time that I'd get a better answer if the LLM had a bit more context on me

      If you already know what a good answer is why use a LLM? If the answer is "it'll just write the same thing quicker than I would have", then why not just use it as an autocomplete feature?

      • Nition 14 hours ago

        That might be exactly how they're using it. A lot of my LLM use is really just having it write something I would have spent a long time typing out and making a few edits to it.

        Once I get into stuff I haven't worked out how to do yet, the LLM often doesn't really know either unless I can work it out myself and explain it first.

        • cruffle_duffle 14 hours ago

          That rubber duck is a valid workflow. Keep iterating at how you want to explain something until the LLM can echo back (and expand upon) whatever the hell you are trying to get out of your head.

          Sometimes I’ll do five or six edits to a single prompt to get the LLM to echo back something that sounds right. That refinement really helps clarify my thinking.

          …it’s also dangerous if you aren’t careful because you are basically trying to get the model to agree with you and go along with whatever you are saying. Gotta be careful to not let the model jerk you off too hard!

          • Nition 14 hours ago

            Yes, I have had times where I realised after a while that my proposed approach would never actually work because of some overlooked high-level issue, but the LLM never spots that kind of thing and just happily keeps trying.

            Maybe that's a good thing - if it could think that well, what would I be contributing?

      • svachalek 13 hours ago

        You don't need to know what the answer is ahead of time to recognize the difference between a good answer and a bad answer. Many times the answer comes back as a Python script and I'm like, oh I hate Python, rewrite that. So it's useful to have a permanent prompt that tells it things like that.

        But myself as well, that prompt is very short. I don't keep a large stable of reusable prompts because I agree, every unnecessary word is a distraction that does more harm than good.

        For example when I'm learning a new library or technique, I often tell Claude that I'm new and learning about it and the responses tend to be very helpful to me.

    > The first response is always the best and I try to one shot it every time. If I don't get what I want, I adjust the prompt and try again.

    I've really noticed this too and ended up taking your same strategy, especially with programming questions.

    For example if I ask for some code and the LLM initially makes an incorrect assumption, I notice the result tends to be better if I go back and provide that info in my initial question, vs. clarifying in a follow-up and asking for the change. The latter tends to still contain some code/ideas from the first response that aren't necessarily needed.

    Humans do the same thing. We get stuck on ideas we've already had.[1]

    ---

    [1] e.g. Rational Choice in an Uncertain World (1988) explains: "Norman R. F. Maier noted that when a group faces a problem, the natural tendency of its members is to propose possible solutions as they begin to discuss the problem. Consequently, the group interaction focuses on the merits and problems of the proposed solutions, people become emotionally attached to the ones they have suggested, and superior solutions are not suggested. Maier enacted an edict to enhance group problem solving: 'Do not propose solutions until the problem has been discussed as thoroughly as possible without suggesting any.'"

      Not in the same way. LLMs are far more annoying about it.

      I can say: I'm trying to solve problem x. I've tried solutions a,b, and c. Here are the outputs to those (with run commands, code, and in markdown code blocks). Help me find something that works " (not these exact words. I'm way more detailed). It'll frequently suggest one of the solutions I've attempted if they are very common. If it doesn't have a solution d it will go a>b>c>a>... and get stuck in the loop. If a human did that you'd be rightfully upset. They literally did the thing you told them not to, then when you remind them and they say "ops sorry" they do it again. I'd rather argue with a child

            To be clear re my original comment, I've noticed that LLMs behave this way. I've also independently read that humans behave this way.

  • stingraycharles 14 hours ago

    Yes, your last paragraph is absolutely the key to great output: instead of entering a discussion, refine the original prompt. It is much more token efficient, and gets rid of a lot of noise.

    I often start out with “proceed by asking me 5 questions that reduce ambiguity” or something like that, and then refine the original prompt.

    It seems like we’re all discovering similar patterns on how to interact with LLMs the best way.

    • LTL_FTC 13 hours ago

      We sure are. We are all discovering context rot on our own timelines. One thing that has really helped me when working with LLMs is to notice when it begins looping on itself, asking it to summarize all pertinent information and to create a prompt to continue in a new conversation. I then review the prompt it provides me, edit it, and paste it into a new chat. With this approach I manage context rot and get much better responses.

    • jasonjmcghee 13 hours ago

      The trick to do this well is to split the part of the prompt that might change and won't change. So if you are providing context like code, first have it read all of that, then (new message) give it instructions. This way that is written to the cache and you can reuse it even if you're editing your core prompt.

      If you make this one message, it's a cache miss / write every time you edit.

      You can edit 10 times for the price of one this way. (Due to cache pricing)

      • svachalek 13 hours ago

        Is Claude caching by whole message only? Pretty sure OpenAI caches up to the first differing character.

        • jasonjmcghee 12 hours ago

          Interesting. Claude places breakpoints. Afaik - no way to do mid message.

          I believe (but not positive) there are 4 breakpoints.

          1. End of tool definitions

          2. End of system prompt

          3. End of messages thread

          4. (Least sure) 50% of the way through messages thread?

          This is how I've seen it done in open source things / seems optimal based on constraints of anthropic API (max 4 breakpoints)

      Is it? Aren't input tokens are like 1000x cheaper than output tokens? That's why they can do this memory stuff in the first place.

      • stingraycharles 12 hours ago

        What I mean is that you want the total number of tokens to convey the information to the LLM to be as small as possible. If you’re having a discussion, you’ll have (perhaps incorrect) responses from the LLM in there, have to correct it, etc. All this is wasteful, and may even confuse the LLM. It’s much better to ensure all the information is densely packed in the original message.

    I wish the LLMs would tell you exactly what the input was (system prompt, memory, etc, at least, the ones we have control over, not necessarily their system prompts) that resulted in the output.

    Also, out of curiosity, do you use LLMs for coding? Claude Code, Cursor, etc? I think it's a good idea to limit llm conversations to one input message but it makes me wonder how that could work with code generation given that the first step is often NOT to generate code but to plan? Pipe the plan to a new conversation?

    • theshrike79 2 hours ago

      The basic process is that you use a "plan mode" with whatever model is good at planning. Sometimes it's the same model, but not always.

      You refine your plan and go into details as much as you feel necessary.

      Then you switch to act mode (letting the model access the local filesystem) and tell it to write the plan to docs/ACDC1234_feature_plan.md or whatever is your system. I personally ask them to make github issues from tasks using the `gh` command line tool.

      Then you clear context, maybe switch to a coding model, tell it to read the plan and start working.

      If you want to be fancy, you can ask the plan system to write down the plan "as a markdown checklist" and tell the code model to check each task from the file after it's complete.

      This way you can easily reset context if you're running out and ask a fresh one to start where the previous one left off.

  • mckn1ght 16 hours ago

    Plan mode is the extent of it for me. It’s essentially prompting to produce a prompt, which is then used to actually execute the inference to produce code changes. It’s really upped the quality of the output IME.

    But I don’t have any habits around using subagents or lots of CLAUDE.md files etc. I do have some custom commands.

    • cruffle_duffle 14 hours ago

      Cursor’s implementation of plan mode works better for me simply because it’s an editable markdown file. Claude code seems to really want to be the driver and you be the copilot. I really dislike that relationship and vastly prefer a workflow that lets me edit the LLM output rather than have it generate some plan and then piss away time and tokens fighting the model so it updates the plan how I want it. With cursor I just edit it myself and then edit its output super easy.

      • mckn1ght 10 hours ago

    I make heavy use of the "temporary chat" feature on ChatGPT. It's great whenever I need a fresh context or need to iteratively refine a prompt, and I can use the regular chat when I want it to have memory.

    Granted, this isn't the best UX because I can't create a fresh context chat without making it temporary. But I'd say it allows enough choice that overall having the memory feature is a big plus.

  • liqilin1567 5 hours ago

    It really resonates with me, I often run into this situation when I'm trying to fix a bug with llm: if my first prompt is not good enough, then I end up stuck in a loop where I keep asking llm to refine its solution based on the current context.

    The result is llm still doesn't output what I want even after 10 rounds of fixing requests.

    so I just start a new session and give llm a well-crafted prompt, and suddenly it produce a great result.

  • godelski 4 hours ago

    Honestly it feels weird to call these features "memory". I think it just confuses users and over encourages inappropriate anthropomorphism. It's not like they're fine tuning or building LoRAs. Feels more appropriate to call them "project notes".

    And I agree with your overall point. I wish there was a lot more clarity too. Like is info from my other chats infecting my current one? Sometimes it seems that way. And why can't I switch to a chat with a standard system prompt? Incognito isn't shareable nor can I maintain a history. I'm all for this project notes thing but I'd love to have way more control over it. Really what makes it hard to wrangle is that I don't know what's being pulled into context or not.

    Memory is ok when it's explicitly created/retrieved as part of a tool, and even better if the tool is connected to your knowledge bases rather than just being silod.

      Wasn't me but I think the principle is straightforward. When you get an answer that wasn't what you want and you might respond, "no, I want the answer to be shorter and in German", instead start a new chat, copy-paste the original prompt, and add "Please respond in German and limit the answer to half a page." (or just edit the prompt if your UI allows it)

      Depending on how much you know about LLMs, this might seem wasteful but it is in fact more efficient and will save you money if you pay by the token.

Now, if only I could convince every company on earth to move away from Workday, god I hate that site, and there's no way to get a resume to submit clean/correctly. Not to mention, they can't manage to just have one profile for you and your job history to copy from instead of a separate one for each client.

    I think you're saying a functional LLM is easier to use than a stateful LLM.

  • cruffle_duffle 14 hours ago

    I completely agree. ChatGPT put all kinds of nonsense into its memory. “Cruffle is trying to make bath bombs with baking soda and citric acid” or “Cruffle is deciding between a red colored bedsheet or a green colored bedsheet”. Like great both of those are “time bound” and have no relevance after I made the bath bomb or picked a white bedsheet…

    All these LLM manufacturers lack ways to edit these memories either. It’s like they want you to treat their shit as “the truth” and you have to “convince” the model to update it rather than directly edit it yourself. I feel the same way about Claude’s implementation of artifacts too… they are read only and the only way to change them is via prompting (I forget if ChatGPT lets you edit its canvas artifacts). In fact the inability to “hand edit” LLM artifacts is pervasive… Claude code doesn’t let you directly edit its plans, nor does it let you edit the diffs. Cursor does! You can edit all of the artifacts it generates just fine, putting me in the drivers seat instead of being a passive observer. Claude code doesn’t even let you edit previous prompts, which is incredibly annoying because like you, editing your prompt is key to getting optimal output.

    Anyway, enough rambling. I’ll conclude with a “yes this!!”. Because yeah, I find these memory features pretty worthless. They never give you much control over when the system uses them and little control over what gets stored. And honestly, if they did expose ways to manage the memory and edit it and stuff… the amount of micromanagement required would make it not worth it.

    • Zarathruster 5 hours ago

      From the linked post:

      > If you use projects, Claude creates a separate memory for each project. This ensures that your product launch planning stays separate from client work, and confidential discussions remain separate from general operations.

      If for some reason you want Claude's help making bath bombs, you can make a separate project in which memory is containerized. Alternatively, the bath bomb and bedsheet questions seem like good candidates for the Incognito Chat feature that the post also describes.

      > All these LLM manufacturers lack ways to edit these memories either.

      I'm not sure if you read through the linked post or not, but also there:

      > Memory is fully optional, with granular user controls that help you manage what Claude remembers. (...) Claude uses a memory summary to capture all its memories in one place for you to view and edit. In your settings, you can see exactly what Claude remembers from your conversations, and update the summary at any time by chatting with Claude. Based on what you tell Claude to focus on or to ignore, Claude will adjust the memories it references.

      So there you have it, I guess. You have a way to edit memories. Personally, I don't see myself bothering, since it's pretty easy and straightforward to switch to a different LLM service (use ChatGPT for creative stuff, Gemini for general information queries, Claude for programming etc.) but I could see use cases in certain professional contexts.

    • connorshinn 8 hours ago

      In fairness, you can always ask Claude Code to write it's plan to an MD file, make edits to it, and then ask it to execute the updated plan you created. I suppose it's an extra step or two vs directly editing from the the terminal, but I prefer it overall. It's nice to have something to reference while the plan is being implemented

    Regardless, whatever memory engines people come up with, it's not in anyone's interest to have the memory layer sitting on Anthropic or Open AIs server. The memory layer should exist locally, with these external servers acting as nothing else but LLM request fulfillment.

    Now, we'll never be able to educate most of the world on why they should seek out tools that handle the memory layer locally, and these big companies know that (the same way they knew most of the world would not fight back against data collection), but that is the big education that needs to spread diligently.

    To put it another way, some games save your game state locally, some save it in the cloud. It's not much of a personal concern with games because what the fuck are you really going to learn from my Skyrim sessions? But the save state for my LLM convos? Yeah, that will stay on my computer, thank you very much for your offer.

    • antihipocrat 15 hours ago

      Isn't the saved state still being sent as part of the prompt context with every prompt? The high token count is financially beneficial to the LLM vendor no matter where it's stored.

      • ivape 14 hours ago

        The saved state is sent on each prompt, yes. Those who are fully aware of this would seek a local memory agent and a local llm, or at the very least a provider that promises no-logging.

        Every sacrifice we make for convenience will be financially beneficial to the vendor, so we need to factor them out of the equation. Engineered context does mean a lot more tokens, so it will be more business for the vendor, but the vendors know there is much more money in saving your thoughts.

        Privacy-first intelligence requires these two things at the bare minimum:

        1) Your thoughts stay on your device

        2) At worst, your thoughts pass through a no-logging environment on the server. Memory cannot live here because any context saved to a db is basically just logging.

        3) Or slightly worse, your local memory agent only sends some prompts to a no-logging server.

        The first two things will never be offered by the current megacapitalist.

        Finally, the developer community should not be adopting things like Claude memory because we know. We’re not ignorant of the implications compared to non-technical people. We know what this data looks like, where it’s saved, how it’s passed around, and what it could be used for. We absolutely know better.

            Parent is not chatting though. Parent is crafting a precise prompt. I agree, in that case you don't want memory to introduce global state.

"Before this rollout, we ran extensive safety testing across sensitive wellbeing-related topics and edge cases—including whether memory could reinforce harmful patterns in conversations, lead to over-accommodation, and enable attempts to bypass our safeguards. Through this testing, we identified areas where Claude's responses needed refinement and made targeted adjustments to how memory functions. These iterations helped us build and improve the memory feature in a way that allows Claude to provide helpful and safe responses to users."

Nice to see this at least mentioned, since memory seemed like a key ingredient in all the ChatGPT psychosis stories. It allows the model to get locked into bad patterns and present the user a consistent set of ideas over time that give the illusion of interacting with a living entity.

  • padolsey 9 hours ago

    I wish they'd release some data or evaluation methodology alongside such claims. It just seems like empty words otherwise. If they did 'extensive safety testing' and don't release material, I'm gonna say with 90% certainty that they just 'vibe-red-teamed' the LLM.

  • Xmd5a 15 hours ago

    A consistent set of ideas over time is something we strive for no? That this gives the illusion of interacting with a living entity is maybe something inevitable.

    Also I'd like to stress that a lot of so-called AI-psychosis revolve around a consistent set of ideas describing how such a set would form, stabilize, collapse, etc ... in the first place. This extreme meta-circularity that manifests in the AI aligning it's modus operandi to the history of its constitution is precisely what constitutes the central argument as to why their AI is conscious for these people.

    • dcre 14 hours ago

      I could have been more specific than "consistent set of ideas". The thing writes down a coherent identity for itself that it play-acts, actively telling the user it is a living entity. I think that's bad.

      On the second point, I take you to be referring to the fact that the psychosis cases often seem to involve the discovery of allegedly really important meta-ideas that are actually gibberish. I think it is giving the gibberish too much credit to say that it is "aligned to the history of its constitution" just because it is about ideas and LLMs also involve... ideas. To me the explanation is that these concepts are so vacuous, you can say anything about them.

I think there's a critical flaw with Anthropic's approach to memory which is that they seem to hide it behind a tool call. This creates a circularity issue: the agent needs to "remember to remember." Think how screwed you would be if you were consciously responsible for knowing when you had to remember something. It's almost a contradiction in terms. Recollection is unconscious and automatic, there's a constant auto-associative loop running in the background at all times. I get the idea of wanting to make LLMs more instrumental and leave it to the user to invoke or decide certain events: that's definitely the right idea in 90% of cases. But for memory it's not the right fit. In contrast OpenAI's approach, which seems to resemble more generic semantic search, leaves things wanting for other reasons. It's too lossy.

    create a instruction.md file with yaml like structure on top. put all the instructions you are giving repeatedly there. (eg: "a dev server is always running, just test your thing", "use uv", "never install anything outside of a venv") When you start a session, always emphasize this file as a holy bible to follow. Improves performance, and every few messages keep reminding. that yaml summary on top (see skills.md file for reference) is what these models are RLd on, so works better.

        I agree it's a workaround. Ideally the model should follow instructions directly, or check before running another server to see if it's starting. Though training cannot cover every usecase and different devs work differently, so i guess its acceptable as long as its on track and can do the work.

      Claude has this by way of projects, you can set instructions that act as a default starting prompt for any chats in that project. I use it to describe my project tech stack and preferences so I don't need to keep re-hashing it. Overall it has been a really useful feature to maintaining a high signal/noise ratio.

      In Github Copilot's web chat it is personal instructions or spaces (Like perplexity), In CoPilot (M365) this is a notebook but nothing in the copilot app. In ChatGPT it is a project, in Mistral you have projects but pre-prompting is achieved by using agents (like custom GPT's).

      These memory features seem like they are organic-background project generation for the span of your account. Neat but more of an evolution of summarization and templating.

    Each project should have its own memory and general chats should not pollute that.

    According to the docs "How to search and reference past chats", you need to explicit ask for it, and it's reflected as a tool call. I'm wondering if you just can tell Claude to not look into memory in the conversation, if as they claim, it's so easy to spot Claude using this feature.

Main problem for me is that the quality tails off on chats and you need to start afresh

How many of your chats do you end… “that was rubbish/incorrect, i’m starting a new chat!”

  • rwhitman 13 hours ago

    Exactly, and main reason I've stopped using GPT for serious work. LLMs start to break down and inject garbage at the end, and usually my prompt is abandoned before the work is complete, and I fix it up manually after.

    GPT stores the incomplete chat and treats it as truth in memory. And it's very difficult to get it to un-learn something that's wrong. You have to layer new context on top of the bad information and it can sometimes run with the wrong knowledge even when corrected.

I’ve used memory in Claude desktop for a while after MCP was supported. At first I liked it and was excited to see the new memories being created. Over time it suggests storing strange things to memories (an immaterial part of a prompt) and if I didn’t watch it like a hawk, it just gets really noisy and messy and made prompts less successful to accomplish my tasks so I ended up just disabling it.

It’s also worth mentioning that some folks attributed ChatGPT’s bout of extreme sycophancy to its memory feature. Not saying it isn’t useful, but it’s not a magical solution and will definitely affect Claude’s performance and not guaranteed that it’ll be for the better.

  • visarga 16 hours ago

    I have also created a MCP memory tool, it has both RAG over past chats and a graph based read/write space. But I tend not to use it much since I feel it dials the LLM into past context to the detriment of fresh ideation. It is just less creative the more context you put in.

    Then I also made an anti-memory MCP tool - it implements calling a LLM with a prompt, it has no context except what is precisely disclosed. I found that controlling the amount of information disclosed in a prompt can reactivate the creative side of the model.

    For example I would take a project description and remove half the details, let the LLM fill it back in. Do this a number of times, and then analyze the outputs to extract new insights. Creativity has a sweet spot - if you disclose too much the model will just give up creative answers, if you disclose too little it will not be on target. Memory exposure should be like a sexy dress, not too short, not too long.

    I kind of like the implementation for chat history search from Claude, it will use this tool when instructed, but normally not use it. This is a good approach. ChatGPT memory is stupid, it will recall things from past chats in an uncontrolled way.

      You mean in how Claude interacts with you, right? If so, you can change the system prompt (under "styles") and explain what you want and don't want.

      > Claude doesn’t “think” anything

      Right. LLMs don't 'think' like people do, but they are doing something. At the very least, it can be called information processing.* Unless one believes in souls, that's a fair description of what humans are doing too. Humans just do it better at present.

      Here's how I view the tendency of AI papers to use anthropomorphic language: it is primarily a convenience and shouldn't be taken to correspond to some particular human way of doing something. So when a paper says "LLMs can deceive" that means "LLMs output text in a way that is consistent with the text that a human would use to deceive". The former is easier to say than the latter.

      Here is another problem some people have with the sentence "LLMs can deceive"... does the sentence convey intention? This gets complicated and messy quickly. One way of figuring out the answer is to ask: Did the LLM just make a mistake? Or did it 'construct' the mistake as part of some larger goal? This way of talking doesn't have to make a person crazy -- there are ways of translating it into criteria that can be tested experimentally without speculation about consciousness (qualia).

      * Yes, an LLM's information processing can be described mathematically. The same could be said of a human brain if we had a sufficiently accurate enough scan. There might be some statistical uncertainty, but let's say for the sake of argument this uncertainty was low, like 0.1%. In this case, should one attribute human thinking to the mathematics we do understand? I think so. Should one attribute human thinking to the tiny fraction of the physics we can't model deterministically? Probably not, seems to me. A few unexpected neural spikes here and there could introduce local non-determinism, sure... but it seems very unlikely they would be qualitatively able to bring about thought if it was not already present.

      • deadbabe 15 hours ago

        When you type a calculation into a calculator and it gives you an answer, do you say the calculator thinks of the answer?

        An LLM is basically the same as a calculator, except instead of giving you answers to math formulas it gives you a response to any kind of text.

        • AlecSchueler 14 hours ago

          In what ways do humans differ when they think?

          • withinboredom 13 hours ago

            Humans think all the time (except when they’re watching TV). LLMs only “think” when it is streaming a response to you and then promptly forgets you exist. Then you send it your entire chat and it “auto-fills” the next part of the chat and streams it to you.

            • AlecSchueler 12 hours ago

              Wait, we went from "they don't think" to "they only think on demand?"

              What are we debating? Does anyone know?

              One claim seems to be “people should cease using any anthropocentric language when describing LLMs”?

              Most of the other claims seem either uncontested or a matter of one’s preferred definitions.

              My point is more of a suggestion: if you understand what someone means, that’s enough. Maybe your true concerns lie elsewhere, such as: “Humanity is special. If the results of our thinking differentiate us less and less from machines, this is concerning.”

              • habinero 8 hours ago

                I don't need to feel "special". My concerns are around the people who (want to) believe their statistical models to be a lot more than they really are.

                My current working theory is there's a decent fraction of humanity that has a broken theory of mind. They can't easily distinguish between "Claude told me how it got its answer" and "the statistical model made up some text that looks like reasons but have nothing to do with what the model does".

              • deadbabe 8 hours ago

                If people think LLMs and humans are equal, people will treat humans the way they treat LLMs.

          • habinero 8 hours ago

            Since we have no idea how humans think, that's a pretty unfair and unanswerable question.

            Humans wrote LLMs, so it's pretty fair to say one is a lot more complex than the other lol

            • AlecSchueler 5 hours ago

              > Humans wrote LLMs, so it's pretty fair to say one is a lot more complex than the other

              That's not actually a logical position though is it? And either way I'm not sure "less complex" and "incapable of thought" are the same thing either.

        • xpe 13 hours ago

          My hope was to shift the conversation away from people disagreeing about words to people understanding each other. When a person reads e.g. "an LLM thinks" I'm pretty sure that person translates it sufficiently well to understand the sentence.

          It is one thing to use anthropocentric language to refer to something an LLM does. (Like I said above, this is shorthand to make conversation go smoother.) It would be another to take the words literally and extend them -- e.g. to assign other human qualities to an LLM, such as personhood.

> Most importantly, you need to carefully engineer the learning process, so that you are not simply compiling an ever growing laundry list of assertions and traces, but a rich set of relevant learnings that carry value through time. That is the hard part of memory, and now you own that too!

I am interested in knowing more about how this part works. Most approaches I have seen focus on basic RAG pipelines or some variant of that, which don't seem practical or scalable.

Edit: and also, what about procedural memory instead of just storing facts or instructions?

pronik 13 hours ago

Haven't done anything with memory so far, but I'm extremely sceptical. While a functional memory could be essential for e.g. more complex coding sessions with Claude Code, I don't want everything to contribute to it, in the same way I don't want my YouTube or Spotify recommendations to assume everything I watch or listen to is somehow something I actively like and want to have more of.

A lot of my queries to Claude or ChatGPT are things I'm not even actively interested in, they might be somehow related to my parents, to colleagues, to the neighbours, to random people in the street, to nothing at all. But at the same time I might want to keep those chats for later reference, a private chat is not an option here. It's easier and more efficient for me right now to start with an unbiased chat and add information as needed instead of trying to make the chatbot forget about minor details I mentioned in passing. It's already a chore to make Claude Code understand that some feature I mentioned is extremely nice-to-have and he shouldn't be putting much focus on it. I don't want to have more of it.

I work for a company in the air defense space, and ChatGPT's safety filter sometimes refuses to answer questions about enemy drones.

This looks like a start of a cascade. Capture data (memory) - too much data confuses context - selective memory based on situation - selection is a chore for humans - automate it with a “pre prompt” - that will select relevant memories for the conversation

Now we have conversations that are 2 layers deep. Maybe there are going to be better solutions, but this feels like the solid step up from LLM as tools onto LLM as services.

    Claude Code became almost unusable a week ago with completely broken terminal flickering all the time and doing pointless things so you end up running out of weekly window for nothing.

    I guess OpenAI got it right to go slower with a Rust CLI. It lacks a lot of features but it's solid. And it is much better at automatically figuring out what tools you have to consume less tokens (e.g. ripgrep). A much better experience overall.

    I have also anecdotally noticed it starting to do things consistently that it never used to do. One thing in particular was that even while working on a project where it knows I use OpenAI/Claude/Grok interchangeably through their APIs for fallback reasons, and knew that for my particular purpose, OpenAI was the default, it started forcing Claude into EVERYTHING. That's not necessarily surprising to me, but it had honestly never been an issue when I presented code to it that was by default using GPT.

    Not since skills but earlier as others have said I've noticed Claude chat seems to create tools to create the output I need instead of just doing it directly.

If I just wanted to split on the first space I would've done it myself...

    Claude code has had this for a while (seems old news anyway). In my limited world it really works well, Claude Code has made almost no mistakes for weeks now. It seems to 'get' our structure; we have our own framework which would be very badly received here because it's very opinionated; I am quite against freedom of tools because most people cannot actually really evaluate what is good and what is not for the problem at hand, so we have exactly the tools and api's that always work the best in all cases we encounter and claude seems to work very well like that.

        What do you think a memory system even is? Would you call writing things down on a piece of paper a memory system? Because it is.

It could be intermediary strings of context that it keeps around, we may not know the internals.

Another angle here is data stewardship and transparency...

When a model keeps a running memory of interactions, where is that data going... who has access... how long is it retained...

BUT if the goal is to build trust, more user‑facing controls around memory might help... such as the ability to inspect or reset what the model 'knows'...

ALSO from a performance point of view, memory could be used for caching intermediate representations rather than just storing raw conversation context...

A design‑focused discussion on memory might surface some interesting trade‑offs beyond convenience...

I wonder what will win out: first party solutions that fiddle with context under-the-hood, or open solutions that are built on top and provide context management in some programmatic and model-agnostic way. I'm thinking the latter, both because it seems easier for LLMs to work on it, and because there are many more humans working on it (albeit presumably not full time like the folks at anthropic, etc).

Seems like everyone is working to bolt-on various types of memory and persistence to LLMs using some combination of MCP, log-parsing, and a database, myself included - I want my LLM to remember various tours my band has done and musicians we've worked with, ultimately to build a connectome of bluegrass like the Oracle of Bacon (we even call it "The Oracle of Bluegrass Bacon").
