Meet Robin — our own model, private and half-price — Changelog

OA-Robin-Mini-Preview is the first model we built and host ourselves, and it is live now.

Because it runs entirely on our own hardware, your prompts never leave our infrastructure and nothing is retained — the same privacy guarantee as our other Edge models.

Private by default — great for confidential chat, brainstorming and creative work you would rather not send to a third party.
256K context with vision, tool calling and JSON mode, so it slots straight into agents and long-running workflows.
0.5x multiplier — every request costs half a normal one, so you get roughly double the usage from the same plan.

It is a preview, so expect it to keep improving. A much larger model in the same family is coming soon — we will announce it here when it lands.

Try it from the Models page, or just point your client at OA-Robin-Mini-Preview.
