TypeSafe AI's Jev gains early developer traction as open-source agent projects surge

TypeSafe AI's Jev, a newly released decision model that returns typed probabilities instead of prose, is moving quickly from launch claim to developer experiments as open-source projects build it into browser and trading loops. The most visible examples are browser-use/jev-ultrafast, a browser agent that lets Jev choose the next operation and target, and jarrodwatts/jev-trader, a Monad market-making demo that asks Jev for a buy-or-sell decision on each block.
