auto-max, auto-pro, auto-lite, auto-free — name a tier, get the right model — Changelog

Four new model names pick a model for you: auto-max, auto-pro, auto-lite and auto-free.

Each tier keeps a pool of its three to five fastest models, measured from the last 24 hours of real traffic. On the first turn of a conversation a small decisions model reads the request once and picks the model in that pool best suited to it: coding, agent loops with tools, long documents, images, or plain chat. The pick stays with the conversation, so an agent session does not hop models mid-task and prompt caching keeps working.

You always know what answered. The response's model field and an X-Auto-Model header name the model that served the request, and quota is charged at that model's rate. If the picker is unavailable, the fastest model in the pool answers. Plan rules are unchanged: auto-max needs a plan that reaches max-tier models, and auto-free works on every plan.

Koda uses auto-pro by default from its next release.
