MiMo-V2.6-Pro: Open-Weight Trillion-Parameter Reasoning for Long-Horizon Agents MiMo-V2.6-Pro is Xiaomi's flagship MiMo-V2.6 model, an MIT-licensed sparse Mixture-of-Experts system with roughly 1.02T total and 42B active parameters. It sits at the top of the MiMo lineup above V2.6-Flash and the faster Pro-UltraSpeed variant. What sets it apart is scaled reinforcement-learning training for agentic and long-horizon work, paired with a 1M-token context window and native text, image, audio, and video input. Teams building coding agents, research assistants, and multi-step tool-driven workflows benefit most, particularly where cost efficiency and open weights matter.

Performance

Why MiMo-V2.6-Pro Leads Open-Weight Agentic Work

MiMo-V2.6-Pro is built for long-horizon agentic tasks and complex coding rather than short chat turns. At launch it scored 46 on the Artificial Analysis Intelligence Index, the top open-weight result on that leaderboard, and Xiaomi reports 78.6 on SWE-Bench Verified in Thinking Mode. Because these gains come from reinforcement-learning training across programming, vision, and tool-use tasks, the model generalizes well across different agent harnesses. For production, that means more reliable multi-step tool execution and code resolution. It occupies a low-cost tier for its intelligence class, making high-volume agentic pipelines economically viable.

Benchmarks

MiMo-V2.6-Pro Benchmarks: Intelligence, Speed, and Tool Reliability

On the Artificial Analysis Intelligence Index, MiMo-V2.6-Pro scores 46, placing it as the highest-scoring open-weight model at launch and competitive with several proprietary models around that tier. Independent measurement puts output speed near 130 tokens per second on Xiaomi's API, above the median for comparable open-weight models, though the model is noted as somewhat verbose. Xiaomi's own reporting shows tool-calling accuracy in Thinking Mode reaching 97% and an AA-IFBench instruction-following score of 72, both material for agentic reliability. Independent evaluators note remaining gaps versus top proprietary models in some terminal and cybersecurity tasks.

Technical Specifications

What the model supports

MiMo-V2.6-Pro accepts text, image, audio, and video input and returns text only; it is not an image or audio generator. It pairs a 1,048,576-token context window with up to roughly 131,072 output tokens, so long inputs do not automatically imply long generations. A toggleable Deep Thinking mode enables chain-of-thought reasoning, but when enabled the model forces recommended temperature and top_p defaults. The API is OpenAI- and Anthropic-protocol compatible with function calling and JSON-schema structured outputs. The MIT license permits self-hosting and commercial use, a key differentiator versus proprietary competitors.

Limitations & Trade-offs

Where mimo-v2.6-pro falls short

1
Text-only output. MiMo-V2.6-Pro accepts text, image, audio, and video input but returns text exclusively. It cannot generate images, audio, or video, so multimodal-generation use cases require a separate model. Teams needing visual or speech output should not treat its omnimodal input as full multimodality.
2
Verbosity and reasoning overhead. Independent analysis notes the model is somewhat verbose, and Deep Thinking generates reasoning tokens that count toward output usage. This increases cost and end-to-end latency on complex tasks. For simple, high-frequency requests where thinking adds little value, disabling Deep Thinking or choosing a smaller model such as MiMo-V2.6-Flash is more economical.
3
Single-provider API access and Chinese-hosted servers. The model is tracked as available through one primary API provider (Xiaomi), whose endpoints are China-based. Organizations with data-residency or vendor restrictions on Chinese servers may face compliance friction. The MIT license does allow self-hosting the open weights, but that shifts significant GPU and operational cost onto the team.
4
Remaining gaps versus top proprietary models. While MiMo-V2.6-Pro leads open-weight rankings, independent evaluators report it does not universally match leading closed-source models, with noticeable gaps in some terminal-operation and cybersecurity tasks. For workloads dominated by those specific domains, a frontier proprietary model may still be the safer choice despite higher cost.

Best-Fit Workloads

Where this model earns its place

01

Long-horizon coding agents


With a Xiaomi-reported 78.6 on SWE-Bench Verified in Thinking Mode and tool-calling accuracy reported at 97%, MiMo-V2.6-Pro is well-suited to autonomous software-engineering agents that resolve issues, refactor, and run multi-step tool sequences. Its 1M-token context accommodates large repositories and long tool traces in a single pass. Combined with its low cost tier, this makes sustained, high-volume coding-agent runs practical where proprietary alternatives are more expensive.

02

Large-context research and document analysis


The 1M-token context window lets the model ingest entire research corpora, literature sets, or multi-document knowledge bases without chunking heuristics. Xiaomi highlights research use such as reviewing literature, forming hypotheses, and shortlisting candidates. For RAG-adjacent and long-document workflows, the large window plus strong reasoning reduces context-management complexity, though verbose Deep Thinking output should be budgeted for on very long tasks.

03

Omnimodal understanding pipelines


Native text, image, audio, and video input in a single model supports workflows that reason across mixed media — analyzing screenshots alongside logs, or video and audio alongside text instructions. Because output is text only, it fits classification, extraction, description, and reasoning tasks rather than media generation. This suits agents that must perceive multimodal context and act via tools.

04

Self-hosted, cost-controlled deployment


Because MiMo-V2.6-Pro ships under an MIT license with open weights on Hugging Face, teams can fine-tune and self-host without per-token API fees or dependence on China-based endpoints. This suits organizations with data-residency requirements or very high volumes where owned infrastructure amortizes GPU cost. The trade-off is the substantial hardware needed to serve a trillion-parameter MoE model efficiently.

Frequently Asked Questions

Answers to common questions about integrating and using this AI model via AnyAPI.ai

MiMo-V2.6-Pro has a 1,048,576-token context window (approximately 1M tokens) and supports up to roughly 131,072 output tokens per request. The large context is intended for long repositories, extended tool traces, and multi-session agent runs. Note that a large input window does not extend the maximum output length.

Yes. MiMo-V2.6-Pro supports a toggleable Deep Thinking mode that performs chain-of-thought reasoning before answering, improving accuracy on complex coding, math, and multi-step tasks. When Deep Thinking is enabled, temperature and top_p are forced to Xiaomi's recommended defaults, and reasoning tokens count toward output usage.

MiMo-V2.6-Pro accepts text, image, audio, and video as input and returns text output only. It is a natively omnimodal understanding model, not a media-generation model, so it cannot produce images, audio, or video. Use it for reasoning, extraction, and analysis across mixed-media inputs.

MiMo-V2.6-Pro scores 46 on the Artificial Analysis Intelligence Index, the top open-weight result at launch, and Xiaomi reports 78.6 on SWE-Bench Verified in Thinking Mode. Independent measurement records output speed near 130 tokens per second on Xiaomi's API. Evaluators note remaining gaps versus top proprietary models in some terminal and cybersecurity tasks.

Yes. MiMo-V2.6-Pro is released under the MIT license with open weights available on Hugging Face, permitting commercial use, fine-tuning, and self-hosting. Self-hosting a trillion-parameter Mixture-of-Experts model (roughly 1.02T total, 42B active) requires substantial GPU infrastructure, so many teams access it via API instead.
