Benchmark Performance & Real-World Utility

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

• SWE-bench Verified Software Engineering (67.2%): 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 (54.8%): 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 (62%): Evaluates formal mathematical problem solving and symbolic derivation, providing foundational logic for algorithmic computing.

• Terminal-Bench Execution (64.5%): Reflects proficiency in interactive command-line environments, shell tool use, and automated DevOps scripting.

• Code Arena Preference Rating (1560 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 185 tokens/second, enabling responsive streaming in developer tools and interactive interfaces.
• Commercial Pricing: Zero per-token inference fee when self-hosted on owned GPU infrastructure (e.g. vLLM or Ollama), with marginal costs limited strictly to hardware compute.
