‼️VLMs/MLLMs do NOT yet understand the physical world from videos‼️ In our recent work, we found that even the most advanced AI models still lag behind humans in one key aspect: reasoning about the kinematic properties of objects from videos. Takeaways: 1. ChatGPT 5.1 leads overall among 21 advanced VLMs, followed by Gemini 2.5 Pro/Flash. 2. Grok 4.1 delivers impressive performance at the lowest API cost. 3. Qwen3-VL is the top-performing open-source model. Read here: https://t.co/5lagvLNE37 🧵1/N

Would immunology be better thought of as a Red Queen's Race? @arijitchakrav @TRyanGregory Madi Stoddard & I recently had a discussion on evolution as a paradigm shift for understanding immunology Video here: https://t.co/W3ZwMDAf6U 1/ https://t.co/EKznSIgWVd

Diagrams for understanding cytokine-immune cell interactions have become incredibly complex, and yet the field still struggles to predict & make sense of the many paradoxical effects of cytokines. These paradoxes have direct impacts on treatment trials. 2/ https://t.co/97ohlX9LJQ

*Frankencell* diagrams are cobbled together from numerous published papers, often showing pathways that could not all occur in the same cell at the same time. Are some of our conceptions of immunology based on *Frankensystems*? 3/ @arijitchakrav https://t.co/xlV2zG125d https://t.co/Upf1gcpaIj

Scientific paradigms frame our view of the world. Signs of a paradigm in crisis include: - increasing complexity - important problems remain unsolved - other paradigms offer competing explanations - lots of paradoxes 5/ https://t.co/XQmbDAcfYn

Every human being has a highly individualized adaptive immune repertoire. Pairs of subjects shared, on average, <1% of their respective B cells. 6/ https://t.co/bKaKwbPAPm https://t.co/g1n96f86ud

Immune cells are often viewed like circuits: with deterministic, predictable, pathway-driven behavior Evolution offers an alternate frame: A population stochastically changing in response to selection pressure & differential fitness 8/ More here: https://t.co/W3ZwMDAf6U https://t.co/Zt9TseN9zj

Often debates about education are framed as non-tech versus AI approaches, but too often, AI ed tech just magnifies the same failures of traditional school. 1/ My latest post: https://t.co/pBqIEFNL4w

Here is one of the texts from the Wonders Grade 3 curriculum. Does this look like a text that is worthy of third graders’ time? https://t.co/0yn9dzbTLa

An Australian (now former) teacher: "I’m rarely required to ‘teach’ anymore. Apparently I’m more valuable as an assessor, an examiner, a data collector. I have had to dull my once-engaging lesson sequences... It is mechanical and rigid and driven.” 5/ https://t.co/Oo7MQ4zggW

When the measure becomes the target, it ceases to be a good measure. This is Goodhart’s Law. 6/ https://t.co/AYUXyzq1wO https://t.co/yRjEfPRB85

This is Claude Sonnet 4.6: our most capable Sonnet model yet. It’s a full upgrade across coding, computer use, long-context reasoning, agent planning, knowledge work, and design. It also features a 1M token context window in beta. https://t.co/TDId3XUSRs

I'd strongly recommend reading this. Incredibly proud to work at Anthropic and (still) optimistic we can find a path forward to develop and use AI responsibly in collaboration with USG. https://t.co/HhVDpMty5p

Stripe CEO @patrickc predicts software will shift from "mass-produced, industrial scale" made "years beforehand" to bespoke, custom software created the moment you need it. "Up until now, the economics of software have been conceived of as fixed cost, then infinitely monetized. That has these kinds winner-take-all dynamics." "But once there are inference costs and custom creation involved, it really shifts."
