Decisions your agent can act on.

Ask a question and list the answers you allow. Our kettei models give each one a probability in milliseconds, so your agent can tell a sure answer from a guess.

Four sizes: kettei fat, chub and core share one API, fat and chub are multimodal, and core and dot are open weights you can run yourself.

Tune the wording, or fine-tune chub or core on your own examples. Each new version must pass its gate before it serves.
