The provider is unnamed during the preview, and community reverse-engineering of its tokenizer and behavior points to MiniMax M3, though the identity is unconfirmed; OpenRouter only routes requests to the model. Space Bunny Alpha is offered through a browser playground, a hosted OpenAI-compatible API, and an MCP tool for Claude Code, Cursor and opencode.", "body_md": "A stealth model gaining traction across coding agents — a 1,000,000-token context window, multimodal input, and strong coding performance, served fast. Try it free in your browser, or drop it into your app via our API.\n\nA stealth preview model with frontier-scale context, served fast — and free while it lasts.\n\nDrop a whole repo, a long transcript, or a book into a single call. 1M tokens in, up to 524k out — no chunking gymnastics.\n\nSpace Bunny Alpha is free right now. Try it in the browser with zero signup, or point your code at our hosted endpoint.\n\nAdjustable reasoning effort, native text-vision-audio-video input, strong coding, and blazing-fast inference.\n\nMost models cap out long before a real codebase or document fits. Space Bunny Alpha takes 1,000,000 tokens in a single call — and returns up to 524,288.\n\nFree in the browser, a drop-in hosted API, straight from OpenRouter, or as a 1M-context tool inside your agent — your call.\n\nThe fastest way to code with Space Bunny for free. Point opencode at our OpenAI-compatible endpoint and go.\n\nopencode setup →\nOne OpenAI-compatible key, no OpenRouter account, no rate-limit surprises. Drop it into any SDK, CLI or agent.\n\nGet an API key →\nPrefer the source? Call stealth/space-bunny-alpha directly. We show you exactly how, plus the caveats.\n\nHow to call it →\nGive Claude Code, Cursor or opencode a 1M-context tool via MCP — offload whole-repo analysis to Space Bunny.\n\nInstall the tool →\nSpace Bunny Alpha is an anonymous ('stealth') large language model available on OpenRouter since September 2026. It has a 1M-token context window, native multimodal input, adjustable reasoning, and strong coding — served fast and, during the preview, for free.\n\nThe provider is anonymous during the preview.
