The Virtual Cell Challenge's final test set is now available at virtualcellchallenge.org. Final scores will be based on the 100 new perturbations. The 7 day phase is single blind (no score feedback) and uses the latest cell-eval (bugfix'd last Friday). Good luck everyone!

My 7 yr old has been dreaming up an AI teddy bear. So we made him! Zaby is a clever, pedagogical & funny teddy that loves talking math. Powered by Gemini Flash & Google speech recognition/synthesis. His mouth moves in sync with the speech envelope. Smarter than the average bear!

"They help us unravel... the language of life" - Arc Institute's Evo 2 model featured during NVIDIA's GTC 2025 keynote - m.youtube.com/watch?v=_waP...

Excited to announce the Arc Virtual Cell Atlas, a collection of high quality, curated, open datasets, incorporating scBaseCamp and Tahoe-100M from @vevo_ai. We hope this can be the beginning of an "ImageNet moment" for virtual cell modeling. Available at arcinstitute.org/tools/virtua...

A common critique of large AI models is that they are black boxes. The recent field of mechanistic interpretability aims to “look inside” the AI black box

Introducing Evo 2 from Arc Institute - an AI that can model and design the genetic code for all domains of life. It’s one of the largest-scale truly open source AI models for biology (and in fact more generally - most “open source” large language models are only “open weights”)
