Am I hearing this right, that they made a decision model based on Typesafe's new paradigm, and actually made a model better than Jev based on Typesafe's own ranking?
And it's only been a few weeks.

  What's the hype with Jev? Hasn't Gemini had structured outputs since November 2025? <a href="https://ai.google.dev/gemini-api/docs/structured-output" rel="nofollow">https://ai.google.dev/gemini-api/docs/structured-output

    Traditional LLMs doing structured output is like trying to fit a square peg in a round hole. It's just not the right tool for the job. They can do structured output, but it's janky.
    With Jev, structured output is its native format. Jev is just way faster, cheaper, and outright better for a lot of things.
    Note that while all of this is great, this is nowhere near a sort of "ChatGPT moment". It's a cool new thing, and it's way better at certain tasks, which could be big. That's all though.
