Space Bunny

Space Bunny provides an online playground and an OpenAI-compatible API for Space Bunny Alpha, an anonymous preview reasoning model. The service advertises a one-million-token context window, up to 524,288 completion tokens, text, image, and video input, text and JSON output, tool calling, and five adjustable reasoning-effort levels. Developers can use it for code review, long-document analysis, visual understanding, structured responses, and agent workflows while retaining control over tool execution and side effects. The playground preview is free, while additional usage is sold through one-time credit packs that do not expire.
