1/Excited to share the first in a series of my research updates on LLM pretraining🚀. Our new work shows *distilled pretraining*—increasingly used to train deployable models—has trade-offs: ✅ Boosts test-time scaling ⚠️ Weakens in-context learning ✨ Needs tailored data curation
Really interesting findings!
sydney sweeney reveals in an interview that her current favourite model is gpt-5. "claude code's been an enjoyable experience. i have loved sonnet/opus 4 for coding but lately anthropic is fucking up and sonnet 4 is pushing too much slop. gpt-5 in cursor/codex been a saviour"
Introducing Oasis 2.0: Our most advanced AI model Transform game worlds & styles in real time. 1080p, 30fps Here’s how to play it live (and also a Minecraft Mod)! 🧵
Thanks AK for sharing our work! 😊
Dot product is essentially a 1-head Transformer without softmax: y = (xW_Q)(wW_K)^\top where the router is hard-coded and the only “expert” is the weighted similarity. And then you only need to train the projection weights and the attention just follows along.

ReLU is essentially an element wise MoE with shared router and expert weights: y= I(w^Tx >= 0^Tx) w^Tx + I(w^Tx < 0^Tx) 0^Tx, where the two experts are parameterized by the w and 0 (zero) vectors. And then you only need to train the expert weights and router just follows along.

FYI, if you’re trying out RICL-pi0 and need tech support, ping me here or on email (or raise a GitHub issue) and I will help fix any issues you run into.

Robot AI brains, aka Vision-Language-Action models, cannot adapt to new tasks as easily as LLMs like Gemini, ChatGPT, or Grok. LLMs can adapt quickly with their in-context learning (ICL) capabilities. But can we inject ICL abilities into a pre-trained VLA like pi0? Yes!…
We came second in the GPT-5 Hackathon. We are building ML for the electric grid. The grid will define the next 100 years. We want to redefine the grid. We are looking for a founding MLE and a founding engineer. Talk soon :)
🧠 Excited to share our DIO work published in Medical Image Analysis! 🚀 Traditional deep learning methods for medical image registration sacrifice optimization robustness for speed and very flexible inference-time customization. DIO bridges this gap with implicit optimization.
For a second I thought someone had dropped the most cursed mixed precision strategy

are there any massive 3d datasets that we wanna try this on?

Very excited to share that GEPA is now live on @DSPyOSS as dspy.GEPA! This is an early code release. We’re looking forward to community feedback, especially about any practical challenges in switching optimizers.
3D convnets are powerful but very memory intensive - a lot of representations like high fidelity occupancy maps, 3d image volumes, climate data, cosmological data cannot be processed at scale because of memory requirements. (1/2)
now that dinov3 is released, cannot wait for the same braindead drill in medical imaging: - someone benchmarks it on mri and compares it to nnunet - someone does a CT comparison - someone claims SOTA registration for the 3312th time (but still unsolved)
