Space Bunny Alpha on OpenRouter: Free Stealth Model With 1M Context, Multimodal Input
heyshrutimishra · x · 2026-09-26
The OpenRouter page for Space Bunny Alpha confirms key details of this stealth model:
- Positioned as an anonymous large model with blazing-fast inference, strong coding ability, and native multimodal input
- 1M-token context, adjustable reasoning effort, currently free
- The unnamed third-party developer stays anonymous during preview; OpenRouter only routes requests and is not the owner
- Data policy: the provider may retain prompts/completions but does not use them for training, per Stealth Model Terms
- Hosted by a single provider with all requests forwarded directly
Free stealth models are typically pre-launch stress tests — worth probing with real coding tasks to gauge its true capability.
