Xiaomi has released two new open-source large language models, MiMo-V2.5 and MiMo-V2.5-Pro, designed for agent-based AI systems such as OpenClaw. The models are distributed under the permissive MIT license, allowing developers and enterprises to use, modify, and deploy them commercially without restrictions. MiMo-V2.5 features 310 billion parameters with 15 billion active during inference, while the Pro version scales to 1.02 trillion parameters with 42 billion active. Both models support context windows of up to one million tokens, targeting long-running and complex tasks.
The release focuses on efficiency in agent workflows, where AI systems perform multi-step operations such as coding, automation, and task orchestration. According to Xiaomi’s benchmarks, MiMo-V2.5-Pro achieved a 63.8 percent success rate on ClawEval while using around 70,000 tokens per task cycle. This represents significantly lower token consumption compared with competing models from Anthropic, Google, and OpenAI. Lower token usage translates directly into reduced operating costs, a key factor as AI pricing shifts toward usage-based billing.
Pricing for the models reflects this positioning. The base MiMo-V2.5 starts at approximately $0.40 per million input tokens and $2.00 per million output tokens, while the Pro version is priced at $1.00 and $3.00 respectively for standard context sizes. Xiaomi also offers extended context support up to one million tokens without imposing significant pricing multipliers, contrasting with industry trends where longer context windows often incur higher costs. The company has additionally introduced subscription-based token plans and temporary incentives such as free cache usage to encourage adoption.
Efficiency as a Differentiator
The MiMo models highlight a shift toward optimizing cost-performance in AI systems, particularly for agentic use cases. By using a mixture-of-experts architecture, the models activate only a subset of parameters during each task, reducing computational overhead while maintaining capability. This approach is increasingly important as enterprises deploy AI agents that operate continuously and consume large volumes of tokens.
For developers, the combination of open licensing and lower costs provides an alternative to proprietary models with usage fees and restrictions. Organizations can run the models locally or in private cloud environments, offering greater control over data and expenses. This flexibility is particularly relevant for applications involving long-running processes or sensitive information.
Open Models Gain Ground
Xiaomi’s release reflects broader momentum behind open-source AI as competition intensifies. The gap between open and closed models has narrowed, with open systems increasingly matching proprietary offerings in performance while offering more flexibility. The MIT license further positions MiMo as infrastructure that can be integrated into a wide range of applications without legal or commercial barriers.
The move also aligns with changes in AI economics, as providers shift from subscription models to metered usage. In this environment, efficient models that reduce token consumption can offer a significant advantage. Xiaomi’s strategy suggests that cost and openness may become as important as raw performance in determining which AI platforms gain adoption in enterprise and developer ecosystems.
