Deep dive
On shared benchmark coverage, MMLU PRO has Claude Sonnet 4.6 at 87.3 and MiMo-V2.5 at 84.9, with Claude Sonnet 4.6 ahead by 2.4 points; Google-Proof Q&A has Claude Sonnet 4.6 at 89.9 and MiMo-V2.5 at 83.7, with Claude Sonnet 4.6 ahead by 6.2 points; AIME 2025 has Claude Sonnet 4.6 at 94 and MiMo-V2.5 at 94.1, with MiMo-V2.5 ahead by 0.1 points. The largest visible gap is 6.2 points on Google-Proof Q&A, which matters most when that benchmark mirrors your workload. Treat isolated benchmark wins as directional, because provider routing, prompt style, and tool access can move real application results.
The capability footprint differs most on code execution: Claude Sonnet 4.6. Both models share vision, multimodal input, reasoning mode, and JSON / Tool use, so the practical split is not just feature count. Use those differences to decide whether the page is about raw model quality, agentic coding support, multimodal ingestion, or predictable structured API behavior.
For cost, Claude Sonnet 4.6 lists $3/1M input and $15/1M output tokens on the cheapest tracked provider, while MiMo-V2.5 lists $0.14/1M input and $0.28/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts MiMo-V2.5 lower by about $6.42 per million blended tokens. Availability is 6 providers versus 2, so concentration risk also matters.
Choose Claude Sonnet 4.6 when coding workflow support and broader provider choice are central to the workload. Choose MiMo-V2.5 when long-context analysis, larger context windows, and lower input-token cost are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship.
