Summary

Miniaax has released the M2.5, a new open-source frontier model designed for real-world productivity, particularly in coding. The M2.5 demonstrates strong performance, achieving 80.2% on Sway Bench, 76.3% on browser comp, and 76.8% on agentic tool calling, while also excelling in office work tasks. It is optimized for efficient execution, running 37% faster on complex workloads and offering significantly lower costs, estimated at $1 per hour for 100 tokens/second or 30 cents per hour for 50 tokens/second. The model features a 204.8K context window and is priced at $0.30 per 1 million input tokens and $120 per 1 million output tokens. Miniaax also offers an "agent" system for office productivity and various access options, including a free chatbot, API access via Open Router, Kilo, or Open Code, and a coding plan.

Key takeaway

For AI Architects and MLOps Engineers evaluating open-source models for production, the Miniaax M2.5 presents a compelling option due to its demonstrated performance in coding and agentic tasks, coupled with significantly lower operational costs. Your teams can deploy this model for complex front-end development, browser-based OS creation, or even 3D simulations, potentially reducing infrastructure expenses while maintaining high output quality. Consider leveraging its free access options this week to assess its capabilities for your specific use cases.
