If I understand correctly, it can play chess and rubic cube better than LLM ? ( may be go too ? )

I was wondering the same! So I asked Astra to build me https://jev-chess-master.vercel.app/ where you play against Jev AI as chess player.

You play White, and Jev plays Black. Rather than asking an LLM to generate move strings or JSON, the backend feeds all server-validated legal candidate moves into Vercel AI SDK's experimental_evaluate(). Jev picks Black's move and outputs its probability distribution across all legal candidates in a single forward pass (~300ms, ~$0.00004/move).

Hope this helps!

ok I've searched, it may not, but it can do "driving car" and "trade 0-DTE Option" much better.
