Deep dive
On shared benchmark coverage, MMLU PRO has GPT-4 Turbo at 69.4 and Xiaomi MiMo-V2.5-Pro at 68.5, with GPT-4 Turbo ahead by 0.9 points; Massive Multitask Language Understanding has GPT-4 Turbo at 86.5 and Xiaomi MiMo-V2.5-Pro at 89.4, with Xiaomi MiMo-V2.5-Pro ahead by 2.9 points. The largest visible gap is 2.9 points on Massive Multitask Language Understanding, 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 vision: GPT-4 Turbo, multimodal input: GPT-4 Turbo, and code execution: GPT-4 Turbo. 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, GPT-4 Turbo lists $5/1M input and $15/1M 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 puts Xiaomi MiMo-V2.5-Pro lower by about $7.43 per million blended tokens. Availability is 6 providers versus 3, so concentration risk also matters.
Choose GPT-4 Turbo when coding workflow support and broader provider choice are central to the workload. Choose Xiaomi MiMo-V2.5-Pro when coding workflow support, 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.
