Life update: I've recently moved to Boston and started a job @AmazonScience ! I'm excited to explore - please share local recs and let me know if you want to grab coffee! (picture: White Mountains, NH)
The news is out! We're starting Blank Bio to build a computational toolkit assisted with RNA foundation models. If you want to see my flip between being eerily still and overly animated check out the video below! The core hypothesis is that RNA is the most customizable molecule…

Giving your models more time to think before prediction, like via smart decoding, chain-of-thoughts reasoning, latent thoughts, etc, turns out to be quite effective for unblocking the next level of intelligence. New post is here :) “Why we think”: lilianweng.github.io/posts/2025-05-…
We wrote up what we've learned about using Claude Code internally at Anthropic. Here are the most effective patterns we've found (many apply to coding with LLMs generally):
Some people today are discouraging others from learning programming on the grounds AI will automate it. This advice will be seen as some of the worst career advice ever given. I disagree with the Turing Award and Nobel prize winner who wrote, “It is far more likely that the…
The past 18 months have seen the most rapid change in human written communication ever By. September 2024, 18% of financial consumer complaints, 24% of press releases, 15% of job postings & 14% of UN press releases showed signs of LLM writing. And the method undercounts true use
Hot off the Servers 🔥💻 --- we’ve found a new approach for scaling test-time compute! Multi-Agent Verification (MAV) scales the number of verifier models at test-time, which boosts LLM performance without any additional training. Now we can scale along two dimensions: by…
One of the things we've been most impressed by internally at Anthropic is Claude 3.7 Sonnet's one-shot code generation ability. Here are a few of my favorite examples I've seen on here over the past day:
87 and 97 both getting golden goals is poetic.
It’s just incredible how much of a home run 4 Nations has been for the NHL and hockey in general. Friends who never watched a hockey game in their lives reaching out asking what the plan is for tonight’s game, what food we’re ordering, etc. Definition of growing the game.
Reading "Distilling Knowledge in a Neural Network" left me fascinated and wondering: "If I want a small, capable model, should I distill from a more powerful model, or train from scratch?" Our distillation scaling law shows, well, it's complicated... 🧵 arxiv.org/abs/2502.08606
Inspired by @karpathy and the idea of using games to compare LLMs, I've built a version of the game Codenames where different models are paired in teams to play the game with each other. Fun to see o3-mini team with R1 against Grok and Gemini! Link and repo below.

progress on math has been so fast. I remember how impressive Minerva was when it came out.. now you need to be good at competitive math to evaluate these latest models.
Been waiting for someone to test this and see if it really works - can multiple AI agents fact-checking each other reduce hallucinations? The answer appears to be yes - using 3 agents with a structured review process reduced hallucination scores by ~2,800% across 310 test cases.

TinyZero reproduction of R1-Zero "experience the Ahah moment yourself for < $30" Given a base model, the RL finetuning can be relatively very cheap and quite accessible.

I'm looking for a postdoc to work on algorithmic fairness, AI alignment, cooperative AI, AI safety, and related topics from the lens of social choice theory. Applications sent in by the end of January will receive full consideration. Details: cs.toronto.edu/theory/positio…
The concept of critical batch size is quite simple. Let’s assume we have a training dataset with 1M tokens. If we use a batch size of 10, we can update model param 100,000 times. On the other hand, if we increase the batch size to 100, the step size decreases to 10,000 (1/n).

I still do this most days and I think it works great. My morning brain (right after 1hr exercise and 1 coffee) is quite eager to work and I go directly to the one top priority item. The energy decreases over time and with every distracting item loaded into the context window.
