Grok 4.1 vs Xiaomi MiMo-V2.5-Pro

Grok 4.1 (2025) and Xiaomi MiMo-V2.5-Pro (2026) are agentic coding models from xAI and Xiaomi. Grok 4.1 ships a 2M-token context window, while Xiaomi MiMo-V2.5-Pro ships a 1M-token context window. This comparison covers specs, pricing, capabilities, benchmarks, provider availability, and production fit. It focuses on practical selection signals rather than broad model-family marketing. The goal is to make the tradeoff clear before deeper testing.

Xiaomi MiMo-V2.5-Pro is safer overall; choose Grok 4.1 when long-context analysis matters.

Deep dive

The capability footprint differs most on multimodal input: Grok 4.1, function calling: Xiaomi MiMo-V2.5-Pro, tool use: Xiaomi MiMo-V2.5-Pro, and structured outputs: Xiaomi MiMo-V2.5-Pro. Both models share the core language-model surface, 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.

Pricing coverage is uneven: Grok 4.1 has no token price sourced yet and Xiaomi MiMo-V2.5-Pro has $1/1M input tokens. Provider availability is 0 tracked routes versus 1. Treat unknown pricing as an integration gap, then verify the route you will actually call before estimating production spend.

Choose Grok 4.1 when long-context analysis and larger context windows are central to the workload. Choose Xiaomi MiMo-V2.5-Pro when coding workflow support and broader provider choice are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship. This keeps the decision grounded in measurable tradeoffs instead of brand-level assumptions. It also helps separate model capability from provider packaging, which can change cost and latency.

FAQ

Which has a larger context window, Grok 4.1 or Xiaomi MiMo-V2.5-Pro?

Grok 4.1 supports 2M tokens, while Xiaomi MiMo-V2.5-Pro supports 1M tokens. That gap matters most for long documents, large codebases, retrieval-heavy agents, and conversations where earlier context must remain visible.

Is Grok 4.1 or Xiaomi MiMo-V2.5-Pro open source?

Grok 4.1 is listed under Proprietary. Xiaomi MiMo-V2.5-Pro is listed under Proprietary. License labels affect whether you can self-host, redistribute weights, or rely only on hosted APIs, so confirm the upstream license before deployment.

Which is better for multimodal input, Grok 4.1 or Xiaomi MiMo-V2.5-Pro?

Grok 4.1 has the clearer documented multimodal input signal in this comparison. If multimodal input is mission-critical, validate it against the provider endpoint because model-level support and API-level exposure can differ.

Which is better for function calling, Grok 4.1 or Xiaomi MiMo-V2.5-Pro?

Xiaomi MiMo-V2.5-Pro has the clearer documented function calling signal in this comparison. If function calling is mission-critical, validate it against the provider endpoint because model-level support and API-level exposure can differ.

Which is better for tool use, Grok 4.1 or Xiaomi MiMo-V2.5-Pro?

Xiaomi MiMo-V2.5-Pro has the clearer documented tool use signal in this comparison. If tool use is mission-critical, validate it against the provider endpoint because model-level support and API-level exposure can differ.

Where can I run Grok 4.1 and Xiaomi MiMo-V2.5-Pro?

Grok 4.1 is available on the tracked providers still being sourced. Xiaomi MiMo-V2.5-Pro is available on OpenRouter. Provider coverage can affect latency, region availability, compliance posture, and fallback options. Use this as a quick comparison signal, then confirm the provider-specific limits before committing to production.
