Everyone's talking about AI-designed antibodies. Having sat through several such "revolutions," I was wondering, is this the real one, or just another flop? So I wrote a long-form essay on whether it holds up. Spoiler: the science checks out, not so sure about the business.

Yes: start from the end. Tech is wired about moving fast, building a prototype, and iterating from there. Success is the next milestone. In bio, one wrong decision today can bite you back in Ph III, after burning 200M and ten years of your life. Obsess about that bio risk.
Seems inevitable tech folks will to some extent relearn the same lessons bio people learned over the years but hopefully in overdrive. Do you have an opinion on what’re likely to be tempting but misguided problems to tackle?

I have gotten much better at these interactions since the advent of LLMs. I just reply 'Okay, assume you *can* give me a probability based on vibes, what is it?'.
Extracting a probability from a doctor is one of life's unnecessary boss battles. Even if you beg them for an interval-valued subjective probability, and at that point you're basically asking for their hunch. I don't know if they get sued for giving out information or something.

The kid in me has been waiting for LLMs all his life. The answer to any random question, always one line of typing away. Some examples just from this week: - What's tattoo ink made of? - Why do double-deckers exist? - Why do Mediterranean countries throw rice at weddings? - How do SSDs work at the micro level?

Too late to explore the Earth, too early to explore the stars. Just in time to explore our own biology using frontier AI.

excited to welcome @JohnJumperSci to @AnthropicAI ! John's work on AlphaFold opened the door for me and many other recovering physicists to contribute to this field. we need many more "AlphaFold moments" in AI x Bio and I'm stoked to have John on board
A bit of news: After nearly 9 years, I have decided to leave Google DeepMind and join Anthropic (after taking some time to recharge). I am incredibly grateful for my time at GDM. @demishassabis took a real chance letting me lead the AlphaFold team just six months after finishing my PhD, and the entire GDM team taught me so much about how to do great science. GDM is a special place, and I’ll still be excited to hear about what amazing things they discover next.

One of the best takes I have read recently. @cremieuxrecueil explains why so many folks are getting AI for Biology wrong.
Anthropic, please don't ruin bio for everyone Link below

as a Spaniard this is such a culture shock at events, we talk about food, rent, football, where someone's from... then you move to SF and people are like “what problem are you obsessed with?” brother I am obsessed with dinner
Been in SF for almost 2.5 years. And figured two types of people: Camp 1: Stanford or Berkeley? Which company? How much equity? Know any VCs? Camp 2: What’s the last thing that changed how you think? What problem are you obsessed with? What did you read last? One exhausts me. The other reminds me why I moved here. 😅

Excited to see what the ESM team has been cooking for the last two years!
Today we're announcing ESMFold2, an open scientific engine to power prediction, design, and discovery across protein biology. The new model delivers state of the art performance on protein interactions, especially antibodies, a critical modality for therapeutics. We have designed and validated miniprotein binders and single chain antibodies across five therapeutic targets that are important in cancer and immunology. We are seeing very high success rates, and affinities at levels consistent with therapeutic activity. We’re also releasing an atlas of 6.8 billion proteins, and 1.1 billion predicted structures. ESMFold2 is built on a state of the art language model that has been trained on billions of protein sequences. A world model of protein biology emerges through language modeling. We’ve used the techniques of mechanistic interpretability developed to understand large language models to understand the concepts ESM uses to represent proteins. The model’s representation space has a compositional organization of features across scales, levels of complexity, and abstraction, that reflects and mirrors the understanding of protein biology developed through a century of empirical science. This understanding emerges without prior knowledge, just from language modeling of protein sequences. Language models are becoming a powerful substrate to understand and program biology. The design of protein interactions is one of the most fundamental problems in biophysics, and has critical implications for the discovery of new medicines. A simple gradient based search with the model was able to discover high-affinity protein binders. I'm excited by the potential this has to accelerate basic science and the understanding of proteins. And especially for the new avenues it opens up for therapeutic design and medicine.

Watching Elon dump on a literal child prodigy for having "PhD" in their handle, after he made valid points about his company strategy... ...is why I can't abandon this app.
Putting “Ph.D.” in your social media name is a sure sign of a pompous retard

Spent part of today rewriting eager-style PyTorch snippets because XLA kept recompiling on different batch sizes. Very humbling.

Beginning to experiment seriously with TPUs for model training. Working with XLA reminds me of the good old days writing neural networks in TensorFlow 1: static graphs, compilation...

You were never alone, Gary, though you were the first to bite the bullet, to fight the good fight, and to make the argument well, again and again, for the limitations of LLMs. I salute you for this good service!

Microsoft claims their new AI framework diagnoses 4x better than doctors. I'm a medical doctor and I actually read the paper. Here's my perspective on why this is both impressive AND misleading ... 🧵

1/ AlphaFold is a revolutionary leap in biology. This has gifted us the AlphaFold Database (AFDB). But what happens when we use this data to train other models? We found a crucial catch. 🧵 arxiv.org/abs/2506.08365 #ProteinDesign #Bioinformatics #AlphaFold

Note that I don't think the AF3 authors have a single stupid hair between them all. Public AF3 is just a watered down version of their model, trained on public data. The real deal will be the full model trained on their private data moat.

Anyway, those are my thoughts. Please do read the paper and take your own conclusions. Congratulations to the authors for the great work! And thanks to @NaefLuca who brought this paper into my feed!
