Benchmark Performance & Real-World Utility

In standardized laboratory and real-world evaluation suites, MiMo-V2.6-Pro demonstrates calibrated proficiency across key performance vectors:

• SWE-bench Verified Software Engineering (78.4%): Measures multi-file GitHub issue resolution. The model demonstrates practical capability in localizing source code bugs, synthesizing functional patches, and passing rigorous integration test matrices. For evaluation methodology, consult our SWE-bench Pro guide.

• GPQA Diamond Scientific Reasoning (65.2%): Assesses graduate-level domain problem solving across physics, chemistry, and biology, minimizing hallucinations in multi-step deductive arguments. See our Humanity’s Last Exam benchmark analysis.

• MATH-500 Competition Mathematics (74.5%): Evaluates formal mathematical problem solving and symbolic derivation, providing foundational logic for algorithmic computing.

• Terminal-Bench Execution (76.2%): Reflects proficiency in interactive command-line environments, shell tool use, and automated DevOps scripting.

• Code Arena Preference Rating (1745 Elo): Validates human developer satisfaction in blind side-by-side coding evaluations against contemporary alternatives.

Inference Latency & Cost Architecture

• Token Context Window: 1.0M tokens, allowing large documents, multi-file codebases, and long conversation memories to be processed in a single context window.
• Inference Speed: Reference throughput clocks at approximately 55 tokens/second, enabling responsive streaming in developer tools and interactive interfaces.
• Commercial Pricing: API consumption is billed at $0.44 per 1M input tokens and $0.87 per 1M output tokens, offering predictable scaling for high-volume enterprise traffic.

Strengths, Limitations & Ideal Workflows

Primary Strengths

• World-class cost-to-intelligence ratio: 78.4% SWE-bench Verified and 65.2% GPQA Diamond at just $0.44/1M
• 1,745 LMSYS Arena Elo and 1,585 AA-Briefcase Elo rivaling western flagships
• Full 1M token context window with native multimodal vision, document analysis, and tool orchestration

Known Considerations

• Throughput is balanced (55 tps) rather than ultra-fast

Recommended Use Cases

Cost-effective agentic coding, complex autonomous workflows, high-difficulty reasoning, and 1M multimodal document processing.
