OpenCode and OpenRouter have started serving Space Bunny, an anonymous reasoning model aimed at coding and tool use, at a listed price of zero. The provider has not said which lab trained it, and the two routes do not make the same promise about what happens to a prompt.

An unnamed coding model, priced at zero

Space Bunny is free on OpenCode and on OpenRouter. The lab has not put its name on the model, and the two routes do not treat prompts the same way.

Token-count probes on the OpenCode route

24 prompts, three families

Column height is the number of exact matches. Same test, same unit.

Every probe matched MiniMax. That is a family clue, not a confirmed model name.

What is working

Free coding use, a context window past a million tokens, tool calling, and a zero-retention claim on OpenCode. Eight frontend runs averaged 80 out of 100.

What is unsettled

The maker is unconfirmed. OpenRouter may retain prompts. Scores ran from 100 down to 45, major benchmarks are missing, and the free window is temporary.

Same model name, different data terms

A private codebase is not equally private on every route.

OpenCode Go: not used for training, kept 0 days.

OpenRouter: not used for training, but prompts and completions may be retained.
