Mysterious stealth model Space Bunny Alpha goes free with 1M context, benchmarks vs GPT-6 Astra
WorldofAI · youtube · 2026-09-29
An anonymous stealth model, Space Bunny Alpha, has appeared free on OpenRouter and OpenCode with a 1M-token context window, multimodal input, and adjustable reasoning effort. Hands-on coding and agentic tests pit it against GPT-6 Astra, showing strong coding results and demos from 3D scene generation to building an equity research app from one prompt. Earlier speculation tied it to MiniMax M3.1 Flash, now ruled out; its creator remains unknown.
