Six decision models, two of them free

AnyRouter lists six System One decision models. Liquid d1 and Respan Span-01 Lite are priced at $0. The other four have a paid list rate and run on your own provider key.

Six models, one endpoint

Decision models answer typed questions about application state. They are not chat. Every one of them is called with POST /api/v1/decisions.

The catalog has six:

Two are free

Liquid d1 (d1:free) and Span-01 Lite are listed at $0 per million input and output tokens. Jev, GLiNER2.5-Decide, Kev 4B, and Solar Decide have a non-zero list rate.

All six routes use your own provider key. They do not sit on the platform free-model badge, which is reserved for public routes AnyRouter serves without a key you supply. anyrouter/decision is a preset over these models, not a seventh model.

Try one from the terminal: anyr decision --model liquid/d1.
