Xiaomi has just launched MiMo-V2-Flash, a 309B open weights reasoning model that scores 66 on the Artificial Analysis Intelligence Index. This release elevates Xiaomi to alongside other leading AI model labs. Key benchmarking takeaways: ➤ Strengths in Agentic Tool Use and Competition Math: MiMo-V2-Flash scores 95% on τ²-Bench Telecom and 96% on AIME 2025, demonstrating strong performance on agentic tool-use workflows and competition-style mathematical reasoning. MiMo-V2-Flash currently leads the τ²-Bench Telecom category among evaluated models ➤ Cost competitive: The full Artificial Analysis evaluation suite cost just $53 to run. This is supported by MiMo-V2-Flash’s highly competitive pricing of $0.10 per million input and $0.30 per million output, making it particularly attractive for cost-sensitive deployments and large-scale production workloads. This is similar to DeepSeek V3.2 ($54 total cost to run), and well below GPT-5.2 ($1,294 total cost to run) ➤ High token usage: MiMo-V2-Flash is demonstrates high verbosity and token usage relative to other models in the same intelligence tier, using ~150M reasoning tokens across the Artificial Analysis Intelligence suite ➤ Open weights: MiMo-V2-Flash is open weights and is 309B parameters with 15B active at inference time. Weights are released under a MIT license, continuing the trend of Chinese AI model labs open sourcing their frontier models See below for further analysis:

MiMo-V2-Flash demonstrates particular strength in agentic tool-use and Competition Math, scoring 95% on τ²-Bench Telecom and 96% on AIME 2025. This places it amongst the best performing models in these categories.

MiMo-V2-Flash is one of the most cost-effective models for its intelligence, priced at only $0.10 per million input tokens and $0.30 per million output tokens.

MiMo-V2-Flash generated ~150M reasoning tokens while running the Artificial Analysis evaluation suite, making it one of the most token-intensive model tested - this has latency implications and offsets some of its pricing advantages.

MiMo-V2-Flash scores -62 on the AA-Omniscience Index, driven primarily by a relatively high hallucination rate.
