The company said the model delivers "a generational leap" in agentic tasks, coding, computer use, and cybersecurity\. MiniMax Group Inc confirmed on October 19 that the anonymous model Space Bunny, which topped daily token\-call\-volume rankings on OpenRouter and Opencode within three days of its late\-September launch, is an early version of M3\.1 Flash[6](https://vectorwire.ai/article/minimax-ships-428b-moe-model-m3-1-flash-at-0-15-per-million-input-tokens-5ed6ec#source-6)\. The company's official account posted a video captioned "Welcome back, Space Bunny" to reveal the connection\. MiniMax said M3\.1 Flash nearly triples online inference speed and cuts usage costs by 70%\. Space Bunny processed more than 200 trillion tokens while operating anonymously\. During that period, it joined[DeepSeek\-V4\.1\-Flash](https://vectorwire.ai/models/deepseek-v4-1-flash)and[GLM\-5\.3\-Flash](https://vectorwire.ai/models/glm-5-3-flash)in the top three on the same volume rankings\. A Pro version of M3\.1 Flash is also set to launch soon, according to MiniMax\.
