MiniMax M3.1 Flash, formerly Space Bunny, is live and free for 72 hours on OpenRouter
MiniMax announced on X that the model previously running on OpenRouter under the codename Space Bunny is now released as M3.1 Flash and is free on OpenRouter for 72 hours. MiniMax said Space Bunny ranked first on OpenRouter for 10 straight days and processed 56.7T tokens, the most of any stealth model it has run, before leaving the platform on Oct 5. The company also said developers had been using an early build and thanked OpenRouter for keeping the model's identity secret; the ranking and token figures are MiniMax's own claims.
