System One is live
Amanai supports native structured evaluation through POST /v1/systemone. Send a state and named questions, then receive typed answers in one synchronous response.
What's new
Jev handles noul, choice, and score questions. Choice and score answers include probabilities, making the output suitable for routing, triage, scoring, and other structured decisions. System One has its own contract; it is not a chat-completions model.
Model & pricing
The model ID is amanai/jev-1.13. It costs 0 credits per request while the offer is active. Currently free for a limited time while the upstream free offering remains available. Free access is not guaranteed and future requests may be priced differently. Responses still report input and output token usage. See Billing & pricing for the rate.
Get started
Read the System One guide for request fields, answer shapes, and a complete API example. The endpoint is also listed in the API reference, and the model appears on System status.
