Release 2026.10.13

API changes​

Decisions, in preview​

New POST /v1/decisions (the format of OpenAI's Decisions API) and POST /v1/systemone (compatible with Jev's format) return typed, calibrated answers (probabilities, choices and scores) instead of generated text. Use a Serenity Edge API key. See Decisions.

Image input on the chat models​

POST /v1/chat/completions accepts up to 4 images per request as base64 data URLs in image_url parts, billed as input tokens. Image URLs are refused with HTTP 400. See Models.

Server errors are HTTP 500​

Errors with code upstream_error and timeout now answer HTTP 500 instead of 502 and 504, with the same JSON body and code, so the error object always reaches you. Handle them as before: retry with backoff. See Errors and rate limits.

Models​

Orion Compass decision models​

orion-compass and orion-compass-flash join the catalogue in preview, billed per input token only; output is free. Prices are listed live on Pricing and limits.
