Minimax M2: Building the #1 Open Model – Olive Song, MiniMax
Dec 13, 2025 · 13:41
Olive Song, Senior Researcher at MiniMax, presents the Minimax M2, an open-weight model with 10 billion active parameters that achieves top rankings in intelligence and agentic benchmarks while being cost-efficient for real-world coding tasks. The model's success is attributed to four key characteristics: scaled environments and expert developer feedback for code experience, interleaved thinking with reinforcement learning for long-horizon tasks, perturbation pipelines for robust generalization across agent scaffolds, and small size enabling multi-agent scalability. Song details how these features allow M2 to handle noisy, dynamic environments, perform multi-tool workflows autonomously, and adapt to various scaffolds and prompts. The talk also previews future developments like M2.1 and M3, with plans to integrate audio and video generation capabilities.
