Overview
MiniMax M3.1 Flash is a multimodal mixture-of-experts model positioned for agentic workflows, software engineering, computer use and cybersecurity. MiniMax identifies the earlier anonymous model Space Bunny as an early version of M3.1 Flash. It was released on October 19, 2026. (minimax.io)
Capabilities and uses
- Accepts text, image and video inputs and produces text. It supports a context window of up to 1 million tokens. The model card reports approximately 428 billion total parameters, with 23 billion activated per token. (huggingface.co)
- Suitable for multi-step business workflows, code understanding and development, visual analysis, computer-use tasks, and assisted security analysis. (minimax.io)
- Reasoning is always enabled, with five adjustable effort levels: low, medium, high, xhigh and max. MiniMax reports 73.7% on DeepSWE v1.1 and 61.7 on OSWorld V2; these are publisher-reported benchmarks, not guarantees for individual tasks. (code.minimax.io)
- Available through the MiniMax API, M Plan and MiniMax Code. Model weights are also available for local deployment under the MiniMax community license. (minimax.io)
Limitations
Reasoning cannot be disabled. Image and video generation are not native outputs of this model; visual generation requires separate tools or models. Tool-enabled workflows depend on the environment, access permissions and supplied materials. Outputs, code and security findings should be independently reviewed. Usable local context and throughput depend on hardware and serving configuration. (code.minimax.io)
