TypeSafe AI has released Jev, a System One model that takes typed questions and returns typed, calibrated decisions as probabilities instead of generating text. The company positions it as a machine-readable alternative to chat-style outputs for applications that need structured answers.
Pricing is notable: input costs $0.042 per 1M tokens, and output tokens are free. That puts the cost on the query rather than the response. The announcement includes vendor benchmarks, but TypeSafe also flags caveats, so developers should treat the numbers as vendor-reported.
Developers are already building on the API, according to the announcement. Since there is only one source, there are no independent results or differing views to compare; the claims are TypeSafe's own.
