kettei

Sqwish Labs' decision-model family behind the OneHot API: binary, single-choice, and ordinal decisions — an expected level over ordered answers, a primitive Jev lacks — plus abstention policies, over text or images. kettei-fat ($0.06/M input) and chub ($0.04/M) are multimodal, text-only core is $0.02/M, and the platform wraps them in dataset versioning, teacher labelling, prompt tuning, and gated fine-tunes. Speaks Jev's request/response format natively — repoint a Jev client's base URL — ships MCP tools and a Claude Code PreToolUse hook, and bills no output tokens. JevBench v1.8 still ranks kettei-fat #1 on the API capability view (86.3) and #1 on ImageJevBench v0.3.0 (75.9), though Super Decider and the cheap Myles-G tier now edge it on the cost-weighted composite (#3, 77.7); chub sits #12.
