Deep dive
On shared benchmark coverage, SWE-bench Verified has Claude Haiku 4.5 at 73.3 and MiMo-V2.5-Pro at 78.9, with MiMo-V2.5-Pro ahead by 5.6 points. The largest visible gap is 5.6 points on SWE-bench Verified, 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: Claude Haiku 4.5, multimodal input: Claude Haiku 4.5, and code execution: Claude Haiku 4.5. Both models share JSON / 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, Claude Haiku 4.5 lists $1/1M input and $5/1M output tokens on the cheapest tracked provider, while 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 MiMo-V2.5-Pro lower by about $1.63 per million blended tokens. Availability is 9 providers versus 3, so concentration risk also matters.
Choose Claude Haiku 4.5 when coding workflow support and broader provider choice are central to the workload. Choose 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.
FAQ
Which has a larger context window, Claude Haiku 4.5 or MiMo-V2.5-Pro?
MiMo-V2.5-Pro supports 1M tokens, while Claude Haiku 4.5 supports 200K tokens. That gap matters most for long documents, large codebases, retrieval-heavy agents, and conversations where earlier context must remain visible.
