Space Bunny
Space Bunny is a playground and developer API for reasoning across very large inputs: long documents, codebases, images and video. Its preview model, Space Bunny Alpha, offers a one-million-token context window, text and JSON output, tool calling and five adjustable reasoning-effort levels, so you can trade speed for depth per request. Because the API is OpenAI-compatible, most existing SDKs and apps can point at it by changing the base URL and key. It suits developers who want to drop a whole repository or a stack of PDFs into one prompt, and teams experimenting with multimodal analysis without stitching several models together. The honest trade-offs: the model is an anonymous preview, so there is little public information on who trains it, how it benchmarks or how stable it will be, and that matters if you plan to build production features on it. The free playground is a low-risk way to test whether its long-context reasoning fits your work before paying for extra usage.
