Deep dive

On shared benchmark coverage, MMLU PRO has DeepSeek V4 Pro at 87.5 and Xiaomi MiMo-V2.5-Pro at 68.5, with DeepSeek V4 Pro ahead by 19 points; SWE-bench Verified has DeepSeek V4 Pro at 80.6 and Xiaomi MiMo-V2.5-Pro at 78.9, with DeepSeek V4 Pro ahead by 1.7 points; SWE-bench Pro has DeepSeek V4 Pro at 55.4 and Xiaomi MiMo-V2.5-Pro at 57.2, with Xiaomi MiMo-V2.5-Pro ahead by 1.8 points. The largest visible gap is 19 points on MMLU PRO, 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 reasoning mode: DeepSeek V4 Pro. Both models share function calling, tool use, and structured outputs, 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, DeepSeek V4 Pro lists $0.43/1M input and $0.87/1M output tokens on the cheapest tracked provider, while Xiaomi MiMo-V2.5-Pro lists $0.43/1M input and $0.87/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend is tied on the cheapest tracked routes. Availability is 5 providers versus 3, so concentration risk also matters.

Choose DeepSeek V4 Pro when reasoning depth and broader provider choice are central to the workload. Choose Xiaomi MiMo-V2.5-Pro when coding workflow support and larger context windows are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship.

FAQ

Which has a larger context window, DeepSeek V4 Pro or Xiaomi MiMo-V2.5-Pro?

Xiaomi MiMo-V2.5-Pro supports 1.05m tokens, while DeepSeek V4 Pro supports 1m tokens. That gap matters most for long documents, large codebases, retrieval-heavy agents, and conversations where earlier context must remain visible.
