Space Bunny Alpha is a newly released stealth model available for free through OpenRouter during its launch window. It is a name alias, the same way Ox Alpha and similar models appear under codenames before a full public release, and it is reachable through standard OpenAI-compatible tooling.
About Space Bunny Alpha
New models often debut under an anonymous alias so providers can gauge demand before the official name is announced. Space Bunny Alpha follows that pattern. It is expected to appear across several providers, but the simplest route to try it is OpenRouter, which already exposes it under a stealth model ID.
