Your editor already works. Only the model behind it is expensive — this swaps that part for free.

Cursor, Kilo, Cline: provider “OpenAI compatible”. opencode: add it as an OpenAI provider. Your prompts, tools and MCP stay untouched.
Worth knowing before you sign up
It is a gateway, not a lab — requests are routed to the model providers, so keep secrets out. And DEVWEEK is not printed on Oxion’s own pricing page: it comes from write-ups dated 24 October 2026 and is first-come, so grab it while it is open.

If the code still works when you read this, that is about $114 of Pro for nothing. If it does not, you lost a signup.
