I had 14 tabs open just to keep up with AI.

arXiv, Papers With Code, every leaderboard, HuggingFace, half a dozen RL-env hubs...

So I built one screen for all of it.

The Bloomberg terminal for AI research.
It's called Sophon 🧵

ps - a "sophon" is the proton-sized supercomputer the Trisolarans use to watch all of human science in The Three-Body Problem.

AI moves too fast for 14 tabs.

Sophon is one screen for the whole field. Free, no signup.
