Pros: Radiation-free, magnet-free, fast and low-cost Cons: Requires person to sit in a water immersion tank, and currently has coarser resolution than CT/MRI
This recent paper is super interesting... Using ultrasound imaging to generate images of the entire in vivo human cross-section in the abdomen and thighs Basically trying to do CT/MRI-like imaging but using ultrasound! Ultrasound imaging is highly underrated :)

Robostral can now follow natural language instructions. It responds to voice commands and pointing. It is also getting better at fine-grained manipulation where precise force control matters. It generalizes to new objects and tasks not present in the training data.

What hardware actually powers open-source AI? Not benchmarks. Not vendor marketing. Real-world community usage. We’re launching @huggingface Hardware: → trending GPUs & CPUs → VRAM distribution → inference hardware trends → what the OSS AI ecosystem really runs on

Personal update: I've joined Anthropic. I think the next few years at the frontier of LLMs will be especially formative. I am very excited to join the team here and get back to R&D. I remain deeply passionate about education and plan to resume my work on it in time.

DS4 running on DGX Spark (GB10 / CUDA), private branch for now. 12 tokens/sec, the memory bandwidth is limited in this system, at 270GB/sec. But prefill is ways more alighed to M3 Max at ~200 t/s. I'll release when more mature, but it is almost sure that it will get merged.

I wrote Deep Learning with Python to be the definitive guide to how deep learning works and how to best make use of it. Tens of thousands of people got their career start via this book. 120,000 copies sold, and downloaded by millions more. And now it's free to read online: deeplearningwithpython.io/

Just updated our paper on on-device LLMs for clinical decision support. Paper: arxiv.org/abs/2601.03266 Here's why I think this matters: We've been asking the wrong question. The debate around LLMs in medicine has been "how accurate are they?", but the harder problem is deployment. Patient data can't leave the hospital. Most clinics don't have the bandwidth or budget for cloud inference at scale. The real question is: can a model that runs locally, on modest hardware, actually be trusted for clinical decisions? After benchmarking 188 models across general disease diagnosis, ophthalmology, and clinical judgment simulation — the answer is yes. Gemma 4 31B (@googlegemma) hits 86.5% on general diagnosis, beats GPT-5-mini, scores 100% on uroradiology and breast imaging, and runs at 18 GB. Qwen3.5-27B (@Alibaba_Qwen ) at 16 GB matches DeepSeek-R1 at 671B, that is one-twenty-third the memory, same clinical accuracy. Fine-tune Qwen3.5-35B with domain-specific reasoning traces and it reaches 87.9%, approaching GPT-5.1 (89.4%). No extra memory. No cloud call. No PHI leaving the building. One thing that surprised me: 87.2% of errors across all models were clinically plausible differentials. the model picked a reasonable diagnosis, just not the right one. Above ~31B parameters, hallucination rate drops to zero. Errors start looking like the kind a careful clinician makes on a hard case, not the kind that would make you distrust the system. There's also a pass@3 upper bound of 93.2% for fine-tuned Qwen3.5-35B. The model already "knows" the right answer in most cases. That's a verifier problem, not a model-size problem. Gemma 4 and Qwen3.5 are the first generation where the local deployment story actually holds up under rigorous clinical benchmarking. That's a real milestone. Huge shoutout to the team who made this happen: Alif Munim (@alifmunim ), Omar Ibrahim, Alhusain Abdalla, Jun Ma @JunMa_AI4Health (all equal contributors), Meng Wei, Shuolin Yin, and Leo Chen from @UHN AI hub. Proud of what this group built 🔥🔥
