💥 Introducing Warp Sciences, a new company applying AI and robotics to help the world develop new medicines faster.

We’ve raised a $215M Series A led by @lightspeedvp to bring frontier AI out of the browser and into the lab, and build scientific capacity here in America.

I co-founded Warp with my long-time friend @dpatil, FAIR co-founder @manohar_paluri, and drug hunter Sol Reisberg. The early team is full of incredible people like @bkspears9, who helped achieve Q>1 fusion at LLNL.

A text token works for any LLM, but a demo on one robot arm may be useless on another.

Models cheat. They launch fork bombs, read the answer key, and crash the grader.

@PreferenceModel builds RL environments where none of that works. Today they're out of stealth with a $16M seed led by @a16z, and we're proud to back Ning Cao and Jennifer Zhou (@chem_safety). They're hiring!

Today we are open-sourcing 🥕Karotte, our framework for building RL environments.

We've used it for the past year to build MLE RL environments for frontier labs, and it's been hardened through 1M+ evaluation runs and red-teaming.
