Mystery Stealth Model "Space Bunny" Goes Free Across Platforms, Sparking Community Tests
Starting September 24, an unidentified stealth model dubbed "Space Bunny" (shown as Space Bunny Alpha / Stealth Bunny Alpha on some platforms) was made temporarily free across multiple platforms, triggering intense community testing and speculation. Its true identity remains officially unconfirmed, but the rare combination of free access, a 1M-token context, and multimodal capabilities has drawn many developers.
Confirmed
- opencode announced the model free for one week, highlighting a 1M context window, multimodality, and Zero Data Retention.
- Cline officially launched the model (as Stealth Bunny Alpha) for free, citing fast reasoning, strong coding, multimodal input, and a 1M-token context.
- The model is live on OpenRouter (as Space Bunny Alpha) with adjustable reasoning, text/image/video input, and free access via Nous Portal.
- Command Code offers the same model free on all paid plans, featuring a 1M-token context and multimodality.
- User omarsar0 tested vision tasks and observed self-verification behavior: with a browser, it opened pages, took screenshots, fixed issues, then declared completion; he also generated a playable 3D game from a hand-drawn sketch.
- User iamfakhrealam generated a complete game, "Space Hop"—a bunny hopping across neon space rocks collecting carrots—at 60fps with particle trails and a glass-style menu from a single prompt.
Unconfirmed
- Developer saheedniyi02 speculated the model might be Kimi; this remains personal conjecture with no official confirmation of the model's identity.
Why it matters
- A free stealth model offering 1M tokens of context, multimodal input, and zero data retention is rare and explains the wave of developer testing.
- The single-prompt 60fps playable game and self-verification cases showcase the model's ceiling in coding and visual generation, fueling community discussion.
