OpenRouter revealed that its stealth model "Space Bunny" was MiniMax's M3.1 Flash, which topped OpenRouter's usage leaderboard for 10 straight days while processing 56.7T tokens — the most of any stealth model on the platform.
MiniMax says the final M3.1 Flash is now live on OpenRouter and free for 72 hours. The company positions it for long agentic coding runs where cost adds up fast.
