Xiaomi Launches MiMo-V2.5-Pro with 1M Context Window for Complex Agentic Tasks
Xiaomi released MiMo-V2.5-Pro on April 22, 2026, its flagship model featuring a 1,048,576 token context window and pricing at $1 per million input tokens and $3 per million output tokens.
Technical Specifications
The model's extended context window — just over 1 million tokens — positions it for integration with agent frameworks requiring long-form context retention. Xiaomi claims the model can autonomously complete professional tasks that would take human experts days or weeks, involving more than a thousand tool calls per task.
Benchmark Performance
According to Xiaomi, MiMo-V2.5-Pro achieves top rankings on:
- ClawEval: Benchmark for agentic capabilities (specific score not disclosed)
- GDPVal: General development proficiency evaluation (specific score not disclosed)
- SWE-bench Pro: Software engineering benchmark (specific score not disclosed)
Xiaomi has not released exact numerical scores for these benchmarks at launch.
Target Use Cases
The company positions MiMo-V2.5-Pro for three primary applications:
- General agentic capabilities with extended autonomous operation
- Complex software engineering tasks
- Long-horizon tasks requiring persistent context across multiple steps
The model is available through OpenRouter, which routes requests to providers with automatic fallbacks for uptime optimization.
Pricing and Availability
MiMo-V2.5-Pro is now available at:
- Input: $1.00 per million tokens
- Output: $3.00 per million tokens
This pricing places it in the mid-tier range for flagship models, notably below comparable offerings from Anthropic and OpenAI with similar context windows.
What This Means
Xiaomi's entry with a 1M context window model at competitive pricing adds another option in the expanding agentic AI market. The emphasis on "thousands of tool calls" suggests optimization for complex multi-step workflows rather than single-turn generation. However, without published benchmark scores or independent verification, the claimed performance advantages over existing models remain unconfirmed. The model's actual differentiation will depend on real-world testing in software engineering and agent deployment scenarios.
