Space Bunny Alpha
An anonymous model on free trial — fast, multimodal, and unattributed.
Space Bunny Alpha is a stealth listing: a large multimodal model released on OpenRouter without naming its maker, free to call while it is being evaluated, with a million-token context and adjustable reasoning effort. Vendors do this to collect honest feedback before a launch. Treat it as exactly that — worth trying, not worth building on, since it can be renamed, repriced or withdrawn without notice, and you cannot know whose terms your prompts are going under.
