- We are excited to release the weights of @msftresearch.bsky.social's COLIPRI, our 3D vision–language encoder for chest CT scans, on @hf.co 🤗 Model: aka.ms/colipri Demo: aka.ms/colipri-demo Paper: aka.ms/colipri-paper Why does COLIPRI matter? 🧵0/12 👇
- There is not a lot of paired 3D medical image–report data out there. A pioneering example is CT-RATE (@iethemhamamci, arxiv.org/abs/2403.17834), with samples from 21k patients, a number much smaller than what we see in the natural imaging domain. 🧵1/12
- We first pre-train our encoder only on images (no reports) sourced from different datasets, using a 3D MAE (Wald et al., CVPR 2025). This allows us to leverage more training data, as we did for Rᴀᴅ-DINO (@fepegar.com et al., Nature Machine Intelligence 2025). 🧵2/12

- Reposted by Fernando Pérez-GarcíaIntroducing DINOv3 🦕🦕🦕 A SotA-enabling vision foundation model, trained with pure self-supervised learning (SSL) at scale. High quality dense features, combining unprecedented semantic and geometric scene understanding. Three reasons why this matters👇

Wherein I analyse HCAI & demonstrate through 3 triplets my new tripartite definition of AI (Table 1) that properly centres the human. 1/n

- Reposted by Fernando Pérez-GarcíaSome of the anti-AI stuff feels a bit like when people would say "don't use Wikipedia as a source." It's just like anything else, a piece of information that you weigh against multiple sources and your own understanding of its likely failure modes

- Inspired by itry, I’ve written jtry. It creates a temporary folder with a virtual environment managed by uv containing the passed packages and an empty Jupyter notebook, then opens the notebook in VS Code. Try e.g. curl raw.githubusercontent.com/fepegar/jtry... | bash -s -- transformers pydantic
- Quick TIL: if you have uv installed and you want to try out ANY Python package in an ipython REPL, you can do so just by running uvx --with llm --with sqlite-utils ipython Pass as many --with package options as you like I wrapped it in a shell script, "itry llm" til.simonwillison.net/python/itry

- Great read. “Once there is a concrete path to revenue […], it becomes increasingly more difficult for researchers to continue to ask for full research freedom. Many will be asked to directly contribute to products […], and only a few will be allowed continued freedom in research.”
