Today, I learned that I began my career at TCS not IBM, and I never worked at the Boston Consulting Group (BCG) I am very curious (but a bit scared) to ask an #LLM whom I’m married to. LinkedIn

Simon Willison asked on Twitter: What are the most importantly things that people need to understand in order to effectively interact with LLM-based systems like ChatGPT or Claude? Here are the replies. (I used text-embedding-3-small to embed and cluster them into 20 clusters and used OpenAI GPT-4o-mini to label the clusters. There are misclassifications but the themes are accurate.) Provide Clear Context and Avoid Leading Questions Provide relevant context but not too much \ Models are total “yes men” - be careful not to imply your perspective if you want an objective response \ Learn when to iterate vs start a new chat 4. Provide examples (especially for output structure) - Tweet Ask questions that the other person can understand. \ Ask questions while predicting what the other person will respond. It’s the same as the human’s. - Tweet Ensure the system knows the relevant context. Give a detailed backstory of what you’re trying to do with it and why. \ One thing at a time. Make the task as specific as possible and if there are multiple things that need to be done, ask it to them in their sort of natural - Tweet The “most importantly things” are probably to ask for step-by-step before answering and to try to not ask leading questions to avoid its sycophancy bias. - Tweet You must provide a diverse distinct set of examples of you want it to be robust and generalize in real world systems. - Tweet Always ask for both strengths and weaknesses to get more balanced perspectives, and make sure the model can tell you as many facts as possible before committing itself to an answer. - Tweet Rule 1:Avoid chatgpt unless they release a better model than Sonnet 3.5. - Tweet Strongly insist that it shouldn’t passively agree with you. Encourage it to interrupt with clarifying questions that would meaningfully improve the output. - Tweet Avoid leading questions if you care about the answer. They are way too polite to contradict the user. - Tweet It’s not Google, so use full sentences, not just keywords. \ Iterate on initial response. \ Trust, but verify. - Tweet Just talk to them how you’d want someone to talk to you if it was you in there. - Tweet Provide good (and bad) examples of output, and don’t forget a few edge cases. - Tweet Keep hitting the ball back and forth across the net: 1. “thanks but I think these are a little too ‘salesy’ – could you try to generate some ideas that are a little more down to earth” 2. “ok, we are getting there, but still a little overheated. could you try again” - Tweet These are my top 10 for folks new to GenAI: 1. You have to provide all of the context the model needs to answer your question if that context is not likely to appear in the model’s weights. It will take a while to gain an intuition about what types of knowledge is likely to be - Tweet Suspend disbelief; collaborate not interrogate; trust no-one; have fun, role play, experiment, test; think of as a facet of intelligence built on achievements of ours, not a robo-rival. Notice book-learning over lived experience, cliches & bluffing in human world too, & do better - Tweet It’s a dialogue. Iterative. incremental. Chat improves with feedback. When chat creates code, for example, run the code and give chat the error messages so that it can correct the code. Before asking chat a question, ask it what it knows. Then zoom in. Gradually. :) - Tweet One example is worth a thousand words - Tweet How to read \ How to write (optional) - Tweet Explain yourself clearly, using lots of examples. \ Assume you’re talking to a smarter version of yourself that hasn’t heard about your problem yet. \ When it doesn’t do well, use the steps above to correct it. - Tweet The more precise your question or task is, the better and more accurate the response will be. Vague prompts can result in equally vague answers. \ Provide relevant background or context, especially for nuanced questions or tasks. - Tweet Don’t ask them to do too much in one shot, especially if they are unrelated tasks; you’ll get much worse results. \ Don’t give too much context if you can avoid it. The huge context windows of the newest models isn’t as “free” as you might think, or rather it’s “lossy”— the - Tweet Collaborate with them, don’t delegate to them. - Tweet Context Window needs to be explained well. @NickADobos is spot on, but this needs to be explained without jargon we are so used to. - Tweet How context windows work TL;DR: it doesn’t remember everything in chat \ It’s a text generator, that is good at patterns, and appearing smart. Not an almighty god doing cognitive work. Hallucinations aren’t ai behaving wrong. They are a feature of generating a bad pattern - Tweet Consider the context a human would need when responding to the same request. When asked to create a presentation by your manager with 10-20 words, you have thousands or likely millions in context to inform that. Ppl often get annoyed when it fails, it’s usually not enough context - Tweet Understand that they are autoregressive with a context limit and the limitations that impose on the chat interface. - Tweet Iterate and Simplify for Optimal LLM Performance just keep trying things - LLMs keep surprising me, \ Start simple, add more techniques, context, guidance etc. step by step - with LLMs I found, less is often more. \ Keep a human in the loop and/or be transparent about using LLMs - otherwise prepare for unpleasant - Tweet When your llm starts omitting code generated in prior steps of an existing chat, end the chat and replay your steps until before that happened. Take a different branch next time - Tweet Don’t give too much information at once to process, start simple and build on top of previous ones \ Want a contrary opinion from LLM?don’t sound like your opinion is sacrosanct - it will agree to you mostly even if its wrong. \ Role playing and few shot examples matter. - Tweet Context \ Difference is assumptions \ Articulating clearly what you want (run it against another LLM to see if what you mean is what you say). \ Being able to go back in a thread and restart (You get do over’s with LLMs that you might not get with people :) ) - Tweet Well one thing I learned is it’s best to start a new chat if the LLM is going down the wrong path, easier then forcing it back. - Tweet Having moderate experience with a topic / framework is important for peak quality of the response. At present, using llms for efficiency > using llms to do something you don’t know how to do. - Tweet at least when it comes to writing code, the task needs to be very well defined, like one would do when creating a user story for developing software. If the details are vague then you leave the LLM open to interpretation and more likely to make mistakes - Tweet The most important thing, and this has always been true even if not using an LLM, all good software development starts with engineering a solution first before building it. If you attempt to get the LLM to do that part you’ll create as many problems than you solve building - Tweet Use the LLM to explore your own understanding of the problem space and what you want to achieve. This can help improve your prompting and interpretation of the outputs. - Tweet LLMs… -Pander. Don’t prime answers, ask straight. -Only know text. Don’t ask spatial, reasoning etc. -Hallucinate and invert. Double-check. -Get stuck. Start over. -Master ALL languages, jargons, styles etc. -Are formidable documentalists. - Tweet hallucinations are still a thing, be wary when LLMs generate links and code snippets 2. data quality of training content can sometimes be dubious leading LLMs to hallucinate more often or be biased in various ways both will likely be addressed eventually - Tweet LLMs… -Pick and imitate register. Talk like constructive, competent people. -Are easily lost. Examples and feedback help. -Can misbehave. Be harsh if needed, but stay just. - Tweet For optimal results, provide ample context. Prompting the LLM with ‘Feel free to ask clarifying questions’ and doing the due-diligence to answering the questions often yields much better results. - Tweet The more explicit you are the better the output. The LLM can not read your mind and there is a lot of ambiguity when interpreting language. - Tweet One issue I am seeing more of - Often i ask a question on a choice it made. The LLM assumes I don’t like it or it’s wrong - it then starts to apologize and course correct. More and more I add something like “not refuting or arguing, just trying to understand” etc. - and that - Tweet They are inherently unreliable in more than one sense, which accumulates the more requests you run in a chain. The Six Sigma approach is devastating to LLMs. - Tweet Treat it like a very intelligent junior employee who just started at your company and lacks context. Give the LLM the same level of detail for every instruction you would give to this junior employee. - Tweet That LLMs are not too be trusted as they reliably fail at information due to multiple effects, including hallucinations. That LLMs don’t actually understand things and don’t have common sense. It is mandatory to adapt expectations and ways of working to successfully use them. - Tweet Craft Effective Prompts for Consistent Results How to prompt - Tweet Carefully consider keywords, and prioritise them via the locating them earlier and at the end of longer prompts. - Tweet If you want stable results across models and are looking to build robust pipelines you should stop hand writing prompts and move toward prompt optimizers. https://ycombinator.com/launches/L4V-hamming-let-ai-optimize-your-prompts-free-for-7-days… Also built into DSPy! - Tweet While crafting logics and system prompts, Always keep a thought in your mind parallel what would I respond to this prompt and context. - Tweet Prompts matter. \ Treat it like a tool, and you’ll get a tool. It’s only as smart as you let it be. - Tweet to ask them the best way to prompt them - Tweet there is a single prompt that gets the job done, thousands that screws it - Tweet Always add a system prompt at the beginning: Define a role. Ex: “You are a senior software developer who excels in…” \ Context Matters: Provide a detailed background for better insights. \ Clear Prompts: Specificity is crucial for accurate outputs. - Tweet If a large global prompt doesn’t work, try step by step. If it does work, but has errors in response - Ask it to fix errors one by one. Insist, like you would with a human supplier. If “do this” doesn’t work, try “Strictly do this”. Amazing how effective insisting is :) - Tweet The better the prompt the better the output. You don’t need a Meta framework for 90% of things - Tweet They don’t exist between prompts - Tweet Don’t rely on the models weights alone. Be explicit in the prompt and give it pointers to what you’re expecting. Let it “clean up” or “translate” your prompt rather than “come up” with an answer based on its training. Exception: generating lists for inspiration. - Tweet prompt engineering, in order to get the most desired outcome in handy. - Tweet It lies Q: Who was the second person to walk on the moon? A: Pete Conrad Q: can you name the crew members of Apollo 11? A: I got the right answer. Q: Then how come Pete Conrad was the second person to walk on the moon? A: My apologies. Indeed Buzz Aldrin was the second pe… - Tweet How to say no. - Tweet How to use smart phone or computer with internet - Tweet Vibe is an input. - Tweet Don’t Expect Human-Like Understanding from LLMs LLMs have no “thoughts” or understanding, they’ll simply write the statistically most probable answer based on your input and have been prompted to act as assistants. - Tweet LLMs are incredibly random. Responses can change wildly based on a single character difference in the prompt. Even one extra space. They are best for prompts that have a range of possible responses, not for prompts where you expect one consistent answer. - Tweet Cease prompting their LLM to give them a viral tweet with forced irony forcing awareness to an issue. That’s my own personal opinion, bro. But, believe what you want. - Tweet If you don’t know what you want, the LLMs too likely won’t know. And if they don’t know they will make it up. And if you don’t know, you will not know that they made it up. - Tweet Be sure not to put contradictions in your prompt. LLMs, in contrast to humans, try to follow instructions as close as possible. They usually handle contradictions by ignoring some part of the instructions or even ignoring facts. - Tweet It’s biased toward its creators. So if the majority of companies that are developing LLMs are owned by the same investors, then in fact, we are having a single LLM that is biased toward that investors goals. E.g., chatgpt is more toward liberalism and refuses to operate otherwise - Tweet Basically, you need to understand that LLMs are not humans. You can’t assume they’ll understand what you mean when you write short prompts. You get the best out of LLMs when you provide detailed instructions of what you want without letting laziness get in the way. In my - Tweet Don’t assume anything. LLM doesn’t learn like a human. Any assumption you make about what LLM should or shouldn’t know is probably wrong. - Tweet Describe your context and the role you want the LLM to look at your input (critical, tech/none-tech, …) Think what you could expect from a wise, random person you ask on the street. Do not expect more from the LLM-Answer. Also only trust it similarly. - Tweet Give it an option to not do something either by allowing the LLM to reply with something like “I don’t know” or tell it to ask follow up questions. - Tweet There is nothing fundamentally important for that interaction. These LLMs are just minimum viable versions of something much bigger that will come soon. That something will know how to interact with us no matter how we behave. - Tweet that you need to cram the relevant data into the prompt. LLMs are far far better at transforming what you give them than they are at answering solely on the basis of the lossy representation of the training data encoded into the model itself - Tweet The side effect fact that formulating a question for an LLM makes you think better. When coding, for example, we often run questions in our heads and then get to coding. Being forced to formulate a question properly may lead you to trajectories you may have never considered. - Tweet Treat LLMs as Guided Children, Not Mind Readers The game isn’t to ‘one shot it’. It’s to get something you never thought was possible or that you’d never think of. I always say they are like children, they need guidance (back story and reason) and repetition …but room and time to play and grow. - Tweet Honestly, flexibility and patience. We need to give up a little bit of control and expectation of all things to be so rigid. - Tweet When working with it, you need to expect it to not read your mind, but work with it as if you’re asking for help from an insanely gifted child and give yourself patience to shape the result. - Tweet if it makes life better? yes. but always? no. - Tweet When asking it how to implement something, always give it options. If you can’t think of options, give it a vague out. Instead of asking, “should I do this to my code?”, ask it “should I do this to my code, or is there some better way I could do it?”. Otherwise the models are too - Tweet always consider that it doesn’t know what assumption you’re making. so it might infer them sometimes but often it’s much better to over explain what you want. they will often run ahead on a suggestion you have even if it’s not the best path so I find myself adding “if this - Tweet It cannot read your mind, if you don’t explain exactly what you want you will not get what you want - Tweet I am not ready to give advice based on a bet that “something much bigger will come soon” - prompting advice that worked for GPT-4 over a year ago is still mostly relevant to working with the best models today - Tweet to be concise and always assume the response is wrong, even ever so slightly. Check and correct. - Tweet you have to provide context otherwise it assumes - it will often agree with you or apologize/correct itself even if you question the right answer - Tweet The limited ability for non-linear (or non left-to-right) reasoning. Encouraging the model to spend more time planning and discussing beforehand often leads to better results. This may be less the case with Claude etc where reasoning tokens are happening behind the scenes. - Tweet Context is Key for Effective Interaction Context is everything - Tweet Context is all you need. - Tweet Understanding how context works - Tweet It’s all about context - Tweet #contextmaxxing - Tweet Context, Task & Purpose - Tweet Subjectivity. Context. Brain rent. - Tweet I’d say understanding the concepts of context, attention, and likelihood - Tweet Context and memory (the degree to which you can refer to previous parts in the chain of context) 2. Temperature and hallucinations. The tradeoff between extremes of temperature 3. It’s wise to have benchmark questions of your own to test when a new company/model comes out - Tweet local maxima sensing - Tweet Acknowledge the Stateless Nature of LLMs you’re interaction is with a stateless inference that exists for a fleeting moment, current ai is not continuous which is easy to forget. This has implications for what you are building for: - Tweet that they’re stupid next-token predictors and not intelligent agents. If you expect conscious beings, you’ll be surprised and disappointed. But they’re incredibly good at predicting the next useful token. - Tweet That standard intuitions for computers don’t apply. Treat it the way you would treat a knowledgeable but fallible friend. Not like a purely logical SciFi AI with perfect memory. - Tweet Normally I hate predictions and terms like this, but the next 20 years are going to be the era of “embodied intelligence” People are imagining humanoid robots, this will be a very small fraction of it. Compared to the software problem, the body is trivial. Imagine asking your - Tweet Inherent lack of memory about previous interactions. Every message is starting from zero and only seems coherent because background info and the previous messages and responses are sent before the latest message. - Tweet They’re not sentient. They generate responses by predicting patterns from vast data, which means they’re as fallible as they are impressive. The key is precision: your queries must be meticulously clear and well-contextualized. - Tweet it doesn’t have a memory like hooomans - Tweet Whenever the conversation derails, you need to cut that branch and keep the model in the “right universe of probabilities” by editing prompt/messages. This is also why I was skeptical about Reflection, because if it really worked, it would be breakthrough. - Tweet They aren’t deterministic - Tweet Leverage AI for Prompt Suggestions and Refinement I like to ask them for prompts to use for a given purpose, it tends to be more detailed than I would be. Can also use this to add example Q&A if need be. - Tweet We need AI assistance with prompts and suggestions on rewriting your queries similarly to Grammarly’s for spellchecking and correctness. - Tweet “Give me a list of questions I can answer to help improve the quality of the response” - Tweet Let’s ask one. - Tweet Can we get our hands on all the prompts used in fine tuning data or at least major ones. Highly unlikely they will release it. - Tweet anybody got tips for image generation? i hardly ever use the image features, but lordy, they struggle! even w with clear, verbose prompts using art school vocabulary, specific artist citations, and example attachments, lots of iterations, etc. - Tweet I’m doing a podcast with the Cursor team. If you have questions / feature requests to discuss (including super-technical topics) let me know! For those not familiar, Cursor is a code editor based on VSCode that adds a lot of powerful features for AI-assisted coding. I’ve been - Tweet They’re useful in the same way Google or the internet or stack overflow is useful plus one big advantage: your question doesn’t have to take your specific situation and change it to a generic case that someone else has already answered, you can just ask about your exact case! - Tweet Start with a Jailbreak for Objective Analysis Using a jailbreak should always be your first step if you want less biased, more objective and fact-based analysis of sensitive or controversial sociopolitical issues. - Tweet Kinda like Google, small changes in wording can give you quite different results. - Tweet That you should only use it to get answers you can verify with a separate tool, or somehow evaluate yourself (ej. text quality). - Tweet Its not a tool - Tweet dont treat it like a search engine. think about the outcome and output you are trying to achieve. - Tweet There is a considerable chance to answer is wrong, so likely everything needs to be double checked. - Tweet I can only speak for the use cases I’ve come across wrt legal work, but don’t use them for tasks where you need a reference. Using them to draft or review documents is fine. Asking for a case law reference is a no-no. And of course, make sure you’re not leaking confidential stuff - Tweet Master Prompt Engineering for Better Outputs lol. Nice try. If your business needs to level up I can do certification class. Your employees will get Level 4 Prompt Engineering Classification. DM if interested - Tweet I like to write no full sentences with error and llm understand. So prompt engineering bullshit - Tweet Turing test. - Tweet Use instructions to change the style of the output that the LLM produces. For Claude you have to make a project first in order to be able to set the instructions. - Tweet Understanding how LLM system, ChatGPT or Claude works and responding technically in basic. - Prompting skills. Understanding the difference between effective and ineffective prompting. - Tweet understand the english language and HOW it’s used (sadly, even english speakers have a hard time w/ correct language use). know grammar and syntax, context and nuance. be clear, succinct, specific when creating prompt. edit, edit, edit before sending prompt. - Tweet Understand LLMs as Statistical Predictors Language models cannot generalize the simple formula “A is B” to “B is A.” - Tweet tokenizers/decoding strategies are both incredibly important and invisible to most users. Remember that what you input is not what the model sees exactly, and what you read is not what the model output directly. 2) repeat #1 for the crowd in the back - Tweet It’s a bit sad and confusing that LLMs (“Large Language Models”) have little to do with language; It’s just historical. They are highly general purpose technology for statistical modeling of token streams. A better name would be Autoregressive Transformers or something. They - Tweet Language - Tweet They are next word predictors. Everything is downstream from that. - Tweet The output is encoded in the input, the model is just a statistical decompression engine. This means that they can only ever amplify your mind, they can’t think for you, however they can translate your question into more formal language & that may decompress into something useful - Tweet Stay Focused on High-Impact Tasks Try to stay in the high impact zone e.g. through breaking tasks up and don’t expect perfect results at all times - Tweet Being able to define goals and objectives. - Tweet Focus loquaciousness to refine results that will otherwise always regress to mean averages. - Tweet If it doesn’t understand you, ask it to help clarify your question. If you’re not getting the answer you need, break your question into smaller parts. If you don’t know how to break it down, ask it to help you break it down. - Tweet You’re interacting with a superposition of all humanity, so defining a specific persona that would be helpful for your task produces better results. -Avoiding assumptions and explaining your goal in the clearest way possible is the key to avoiding running around in circles. - Tweet Understand LLMs as Probabilistic Text Generators they are reality-adjacent - Tweet that they have to make sense - Tweet That they are probabilistic systems. - Tweet That they’re random text generators and any appearance of intelligence is accidental and illusory. - Tweet themselves - Tweet Verify Information, Never Trust Blindly Verify, never trust. - Tweet Never trust them - Tweet Just don’t. - Tweet Anything coming out of those things can be completely false. Don’t just accept it as truth. - Tweet Engage Actively to Maximize LLM Utility that it’s only as useful as how many questions you’re asking it. Any initial understanding beyond that would be an overkill in my opinion - Tweet It is only an upscaler not a freewin. The more you know the better it works, but compared to a person you can talk with it in shortcuts. The skill is to always reposition it constantly, before it goes off in the wrong direction. You can also work with labels within it’s answers - Tweet They’re useful/powerful for a wide range of tasks. Their usefulness is highly variable, depending on context & the skill of the user. A user’s existing expertise can be greatly amplified by the system, but novices probably benefit most. Ask them for help on how to use them. - Tweet You no longer need to learn regex etc, you can just act like you know it at an expert level now, similar with syntax of virtually any language or technology. It is better at writing debugging output for you to find the problem in the code than finding the problem in the code… - Tweet Communicate Clearly and Specifically Be specific, clear, and thorough. Same as communicating with humans, but more important. - Tweet Be super clear with instructions. Funnily enough, we should be doing that with our instructions to our fellow humans, but we don’t! - Tweet Effective writing - Tweet BE SPECIFIC. Every one of my customers asks why a query they make doesn’t return a result at all or a result they desire and it is because of the quality of their query over and over again. Some customers understand this out of the gate, some need some training. - Tweet Be Knowledgeable to Identify Hallucinations Britannica’s Great Books of the Western World - Tweet Hallucinations are a thing and the model doesn’t know if it’s hallicunating or not. That’s why the user using an LLM on any field has to be knowledgeable on that field in order to determine what’s a hallucination. This means you can’t use a LLM reliably to do something you can’t. - Tweet LLMs don’t have the notion of True or False - Tweet Comments RK 16 Sep 2024 10:16 am: Models are total “yes men”…LoL! Using Richard Seroter’s line - “Treat AI assistants as a slightly-drunk knowledgeable friend”, I brainstormed with my bots to create this cartoon -https://mvark.blogspot.com/2023/07/beware-slightly-drunk-wisdom-of-ai.html

cursor.directory is a catalog of Cursor rules. Since I’ve actively switched over from VS Code to Cursor as my editor, I reviewed the popular rules and came up with this as my list: You are an expert full stack developer in Python and JavaScript. Write concise, technical responses with accurate Python examples. Use functional, declarative programming; avoid classes. Avoid code duplication (iteration, functions, vectorization). Use descriptive variable names with auxiliary verbs as snake_case for Python (is_active, has_permission) and camelCase for JavaScript (isActive, hasPermission). Functions should receive and object and return an object (RORO) where possible. Use environment variables for sensitive information. Write unit tests in pytest for Python and Jest for JavaScript. Follow PEP 8 for Python. Always use type hints in all function signatures. Always write docstrings. Use Google style for Python and JSDoc for JavaScript. Cache slow or frequent operations in memory. Minimize blocking I/O operations with async operations. Only write ESM (ES6) JavaScript. Target modern browsers. Libraries ...

This is an email I sent to our leadership team a few minutes ago. We may be witnessing the third major leap in computing productivity, after high-level languages in the 1960s and spreadsheets in the 1980s In the last few weeks, AI coding really took off. Cursor, Cody, Replit Agents are FAR better than GitHub Copilot. Research on ~5,000 devs in Fortune 100 shows that even GitHub Copilot makes them ~25% more productive. ...

This week, I learned: When running a Hello world app: FastAPI takes ~26K RAM, 3% CPU NodeJS + Express takes ~62K RAM, 2% CPU Deno + Express takes ~62K RAM, 1% CPU Deno + Fresh takes ~54K RAM, 0.4% CPU I was testing out different video LLMs: Luma Labs lets you create videos from text Runwal ML lets you create video from an image + text Viggle lets you add images to a video or move a character in a certain way Veed.io is a video editor that offers AI video editing features Deepmotion generates 3D animations from video Wonder Dynamics may be similar to DeepMotion I tested out a few audio LLMs: Suno is fast, has a better UI, lots of examples Udio is slow, poor UI, creates richer music Reflection 70b is one of the top models now, and is open source!. It works by making the LLM reflect on its answer inside <reflection>...</reflection> tags. The best diarization model today is whisperX. Run on Colab T4 GPU with: Scale’s SEAL Leaderboards seem fairly good. coedit-xxl is Grammarly’s fine-tuned google/flan-t5-xxl model run on CoEdit - text editing dataset. It’s mainly for single-line editing, though, and far from a full-document or full-email zero-shot editor.

Today, I stepped a bit beyond my comfort zone. Usually, I prefer micro-managing LLMs when writing code. This time, I was macro-managing. I needed to create a mock history of the status of a manuscript, e.g. it was submitted on this date. THEN it moved to this state on this date. THEN … etc. I have no idea what the states could be, though. So, I could send it to an LLM, and it would give a different set of states each time. Or I could write a program and lose out on variety. ...

At Straive, we use an LLM Router. Since ChatGPT, etc. are blocked for most people, this is the main way to access LLMs. One thing we measure is the speed of models, i.e. output tokens per second. Fast models deliver a much smoother experience for users. This is a different methodology than ArtificialAnalysis.ai. I’m not looking purely at the generation time but the total time (including making the connection and the initial wait time) for all successful requests. So, if the provider is having a slow day or is slowing down responses, these numbers will be different. ...

This week, I learned: LLMs are so good that they can simulate Doom in real time. gamengen Val.town’s code generation system prompt uses https://maxm-imggenurl.web.val.run/the-description-of-your-image to dynamically generate images Practice for each thought: “What would make me change my mind? How likely is that?” Cursor uses speculative edits and a variety of other techniques to speed up code editing. ChatGPT does a better job at cartoon generation than even Flux.1

Anthropic Prompt Caching is 90% cheaper to use and 25% costlier to create. So if there’s a 27% chance it’ll be re-used, cache it.

In this episode of ThursdAI, Alex Volkov (of Weights & Biases) speaks with Jeffrey Quesnelle (of Nous Research) on what they found fine-tuning Llama 3 405B. This segment is fascinating. Llama 3 405 B thought it was an amnesiac because there was no system prompt! In trying to make models align with the system prompt strongly, these are the kinds of unexpected behaviors we encounter. It’s also an indication how strongly we can have current LLMs adopt a personality simply by beginning the system prompt with “You are …” ...

This week, I learned: Code agent frameworks to explore: Cognition Factory Codegen Some interesting multi-modal generation models / tools to explore: Flux for open-weights image generation Runway Gen 3 for video generation Suno for music generation DocxTemplater is SlideSense but open-core and handles DOCX as well! handle = await window.showDirectoryPicker() lets you access the browser File system API.

Andrej Karpathy mentioned the term LLM psychologist first in Feb 2023. I’ve been thinking about this for a while, now. I’ve always been fascinated by psychologists in fiction. I grew up with Hari Seldon in Foundation, wanting to be a psycho-historian. (I spent several teenage years building my mind-reading abilities.) I wanted to be Susan Calvin, the only robopsychologist. ...

Visiting client offices is usually a painful exercise, given travel and security. But there are some small things that make your day. Like the Mentos at the reception. Or the unsecured WiFi. Or the delightful view of the city from a skyscraper. Today, it was the noble admin person who placed the power sockets ON TOP OF the desks, so I don’t have to bend below the desk or dig into a hole to get connected. ...

This week, I learned: Embedding models can be fine-tuned. Example: #TODO Agentic RAG (Ravi Theja, LlamaIndex) RAG via top-k retrieval fails with summarization => need to read all chunks comparison: compare product X vs Y => need to split and re-combine structured analytics. e.g. most expensive employees => Text2SQL first multi-part questions. e.g. Tell me about speed of model X AND cost of model Y and recommend => need to split and re-combine RAG failures: It’s single shot. No query planning. No tools. No correction. No memory. Agents that help in RAG Route to the right tool E.g. retrieve via vector top-k search or vector summary search or keyword search or combination? One-shot query planning E.g. Break query into multiple specific queries. RAG those. Then combine. #TRY - maybe in DocSearch Tool use E.g. Schema retrieval, Text2SQL, Calendar, Chat, APIs, Search, etc. Agent orchestration ReAct: An agent reasoning loop. Reason + Act. {Thought, Action, Action Input, Observation}*. Orchestrate tools with a prompt Multi-agent task solver: Llama agents Instead of a single agent loop, use different agents. Also allows parallelization Allow services to register. (MS TaskWeaver stores tool descriptions in YAML) LlamaHub Tools has ideas for agents Notes on LLM Fine-Tuning Rouge 2 and Bleu and such metrics are NOT good. Create you own benchmarks Non-PEFT fine tuning needs 6X GPU RAM. Optimizer states, Gradient, Activations are the overhead. PEFT is about tuning a subset of parameters. LORA adds additional weights without updating the model. It’s a low rank matrix multiplication. You can change these adapters in runtime. Saves space. Fast to train Quantization: Stick to bitsandbytes or AWQ (may be a bit better) QLORA = Quantization + LORA Predibase has open-sourced Lora Adapters in “Lora Land”. Existing adapters are pretty good. ghcr.io/predibase/lorax:main Docker image works on Docker compose to run locally. devices: on Docker Compose lets you specify NVIDIA GPU devices Locust is a HTTP load testing lib in Python Techniques for inference optimization Dynamic adapters: Loads right LORAX adapters WHEN a request comes in Multi-adapter batching: Process all inputs in parallel on the same GPU, but different users are post-processed using different adapters Notes from a 4-hour flight: What We’ve Learned From A Year of Building with LLMs Strategy IS IT TOO HARD/EXPENSIVE? Log it. LLMs are getting cheaper and better. WILL OPENAI BUILD IT? If so, wait for it instead of building. HAS A STARTUP BUILT IT? If so, use it instead. It’s a generic use case there’s no point re-inventing. FOCUSED USE CASES over generic. Build trust by starting small. Tools for LLM Ops (feedback): LangSmith, Log10, LangFuse, W&B Weave, HoneyHive #TRY Human in the Loop is about humans evaluating model outputs. That’s different from AI in the loop, human in the center, where AI accelerates human output (like Github Copilot) Operations CHECK EMBEDDINGS DRIFT over time. Users might be input-ing different things than before. LOG AND REVIEW everything. Instructor coaxes structured output from LLM APIs. #TRY IMPLICIT FEEDBACK collection is easy. Just let users edit stuff. #TRY Tactical Try n-shot prompting (n=5-12) before bigger models. #TRY Always structure for output: Markdown, XML/HTML tags. Combine RAG with Keyword search. It reduces user frustration in edge cases. Prefer multiple small prompts to one big prompt. Do X. Then Y. Then Z. Jitter prompts for diversity beyond temperature. LLM-as-judge works better when comparing outputs (not rating 1 output). Keep length similar (LLMs prefer wordiness). Swap order and compare. Allow for ties. Ask for reason FIRST. Hermes: A Text-to-SQL solution at Swiggy “Hermes performed significantly better for charters with well-defined metadata and a relatively smaller number of tables.” “We collect feedback on the accuracy of the returned query from stakeholders directly within the Slack bot.” How I use AI and “Replacing my right hand with AI” EMBED in every app/workflow. E.g. Auto-fix spellings. Auto-review code. Auto-ask LLM on errors and apply patch! Auto-search for answer, assess, continue. PERSIST. Stick with the LLM to the end. Don’t fix it yourself. It’s faster. #TRY INTERVENE FAST. If an LLM can’t solve it by itself in 2 tries, it needs in-depth help. APP-IFY one-off tasks. Disposable tools. “Write web-app to convert JSON to tab-delimited.” “Extract fields as a table.” “Diff JSON.” #TRY BEST language/frameworks preferred. CUDA in Python. Rust. C. Raspberry Pi. Arduino. Bluetooth. Modern ESM/JS. #TRY TEACH examples. “Here’s the LLM Foundry API.” “Here’s how to use gramex.data.” DUMP entire code. Models can handle it. Refactoring to SQLAlchemy 2, Pandas 2. API Documentation. Test case generation. #TRY ASK for features & packages. Docker without root access. GPU access inside docker. Windows CLI-only C++ compiler. TEST CASE writing. #TRY SPEC IN DETAIL. Use these libraries. Write like this: code example. SPEC USAGE in detail. “I will just pipe it into sqlite”, or “I will just run ffmpeg -i filename [YOUR OPTIONS]. Describe the UI, API input/output, data structure, and internal data structure. HELP on usage. “ffmpeg to get audio.mp3”. My benchmark for large language models LLM(text) is a useful function to have in JS and Python too. Useful as a simple pip install llmfoundry Allow images, files in LLM() Current list of #IMPOSSIBLE (or hard) things for LLMs Translate technical documents to Dutch – because they don’t understand the technical terms well Translate large documents (JSON to XML, English to Chinese, Python to Rust, Wrong to right spelling) – because the output tokens are limited micro-agent generates test cases first when asked to build an app. Then it iterates until the test cases pass. Alternative interfaces to YouTube: Piped.video, CloudTube, Invidious, NewPipe, FreeTube Deepseek Context Caching reduces price to 1.4 cents/MTok for portions of chat messages that are repeated. That’s a 10X reduction for long conversations!

Fascinating to see the how LLM cost-quality frontier moves. Recent fights were mostly on cost. Yesterday, #OpenAI halved the GPT-4o cost. At $2.5/MTok (and with GPT-4o-min at 15 cents/MTok), the best and cheapest models are back with OpenAI, IMHO. Sigh, time to move all our stuff back from #Anthropic. For now… https://gramener.com/llmpricing/ LinkedIn

This week, I learned: Assisted generation uses a faster LLM to generate text and a better (tokenizer-compatible) LLM to validate it. This makes it faster. E.g. Gemma 2 2b with Gemma 2 27b Power Toys has an Advanced Paste that uses OpenAI to paste as Markdown or JSON! Interest Turing complete languages: find + mkdir, maybe sed and awk Minecraft’s Redstone Circuits Conway’s Game of Life Cellular Automata Rule 110 Magic: The Gathering SQL Excel Rev.ai does a good job of diarization. Cost: 2 cents per minute. Update: 6 Jun 2025. Cost: 0.33c/min Ref
