I think a PhD in Geography was excluded from the list of PhD degrees GPT-5 has achieved.
Huge thanks to all the open source projects that've made a lot of the tech we rely on in the world possible: Linux Git FFmpeg PyTorch & TensorFlow Apache & Nginx MySQL, PostgreSQL, SQLite Chromium & Firefox GCC & LLVM Docker & Kubernetes Also, all the open-weight LLMs... and…
LLMs can make sense of retrieved context because of how transformers work. In one of the lessons from the Retrieval Augmented Generation (RAG) course, we unpack how LLMs process augmented prompts using token embeddings, positional vectors, and multi-head attention. Understanding…
We have a very poor understanding of why deep neural networks like transformer models learn the parameters they learn. For example, in the paper below from 2013, the authors demonstrated that 5% of the weights of a trained deep neural network can be used to predict the values of…
You sometimes see this feature in ChatGPT and Gemini when it shows you two answers to the same question in parallel and asks you to choose one. It's especially revealing when you ask for a fix for a bug and you see on the left an entirely wrong assessment of the situation and on…
Every problem whose description contains enough information to solve it and can fit into one or several pages of text can be solved by an LLM finetuned on enough examples of such problems. Really, three years into this, and I still see even smart people falling into this "OpenAI…
Becoming an RL diehard in the past year and thinking about RL for most of my waking hours inadvertently taught me an important lesson about how to live my own life. One of the big concepts in RL is that you always want to be “on-policy”: instead of mimicking other people’s…

I think Jack Dorsey’s new “bitchat” app makes total sense in this day and age We’ve seen similar concepts before – Hong Kong protesters used Bridgefy during the protests for off-grid communication to avoid police surveillance As authoritarianism rises worldwide, data centers…

Wrapped up Stanford CS336 (Language Models from Scratch), taught with an amazing team @tatsu_hashimoto @marcelroed @neilbband @rckpudi. Researchers are becoming detached from the technical details of how LMs work. In CS336, we try to fix that by having students build everything:
If you use "AI agents" (LLMs that call tools) you need to be aware of the Lethal Trifecta Any time you combine access to private data with exposure to untrusted content and the ability to externally communicate an attacker can trick the system into stealing your data!
What if LLMs could learn your habits and preferences well enough (across any context!) to anticipate your needs? In a new paper, we present the General User Model (GUM): a model of you built from just your everyday computer use. 🧵
Every frontier AI system should be grounded in a core commitment: to protect human joy and endeavour. Today, we launch @LawZero_, a nonprofit dedicated to advancing safe-by-design AI. lawzero.org
Agentic Document Extraction just got much faster! From previous 135sec median processing time down to 8sec. Extracts not just text but diagrams, charts, and form fields from PDFs to give LLM-ready output. Please see the video for details and some application ideas.
* The official prompts: docs.anthropic.com/en/release-not… * An analysis of the leaked/exfiltrated prompt: dbreunig.com/2025/05/07/cla…
I’ve been fascinated lately by the question: what kinds of capabilities might base LLMs lose when they are aligned? i.e. where can alignment make models WORSE? I’ve been looking into this with @ChrisGPotts and here's one piece of the answer: randomness and creativity
the LLMs have reached boyfriend levels of intelligence

model fitting? oh yeah "the ancient greek painter zeuxis invented that"
