OpenRouter Lists Anonymous Stealth Model Space Bunny Alpha With 1M Context, Free
socialwithaayan · x · 2026-09-26
OpenRouter has listed Space Bunny Alpha, a stealth model built by an anonymous third-party provider. Key facts:
- Positioned as a blazing-fast model with strong coding ability and native multimodal input, plus adjustable reasoning effort
- 1M-token context window; accepts text, image, and video input
- Currently free to use; OpenRouter notes actual paid prices often run below list price due to caching and discounts
- Measured at 90 tokens/sec with 1.3s time-to-first-token (per community tests)
- Privacy: the provider may retain prompts and completions but not for training, under Stealth Model Terms; OpenRouter says it is not the developer or operator
- Listed release date Sep 23, 2026, hosted by a single direct provider
A classic anonymous-vendor preview, widely suspected to be a major lab's in-the-wild test of a new model.
