Space Bunny Alpha appeared on OpenRouter as an anonymous “stealth” model. OpenRouter lists its release date as September 23, 2026. On AI/ML API it was served as stealth/space-bunny-alpha. It was free during the preview.

The preview took image and text input and returned text. It always reasoned, with adjustable reasoning effort.
