MiMo-V2.6-Flash — reviews, specs & pricing
The efficient half of Xiaomi's MiMo-V2.6 release: 309B total / 15B active parameters under MIT, keeping the 1M-token context and multimodal input of the Pro model.
Summary
Xiaomi's MiMo-V2.6-Flash is an open-source, highly efficient Mixture-of-Experts (MoE) model released under the permissive MIT license. Operating on 15B active parameters out of a 309B total, it retains the premium 1-million-token context window and multimodal capabilities of the Pro variant. This architecture delivers a highly responsive, cost-effective solution optimized for long-context chat and coding workloads.
Sample use case
A software engineering team can deploy MiMo-V2.6-Flash on-premises to audit and refactor legacy codebases by feeding entire repositories into its 1-million-token context window. Developers can ask the model to trace complex bugs across hundreds of files, generate comprehensive API documentation, and suggest modernization strategies. Because of the model's efficient MoE design and MIT license, the team achieves rapid query turnarounds while keeping proprietary corporate code completely secure.
