Model details

MiniMax-M2.5

MiniMax M2.5 is a text-only large language model in MiniMax's M-series lineup, sitting between earlier releases and the newer M2.7 successor that explicitly builds on its foundations. The model was published as open weights under the MIT license by the Shanghai-based MiniMax, making the full parameter set available for self-hosting and downstream research rather than restricting access to a hosted API. Across multiple distribution channels, M2.5 is positioned as a practical engine for software engineering and autonomous agent pipelines, with MiniMax's own product page framing it as state-of-the-art for coding and agent workloads designed for an "agent universe" of interconnected AI tools.

Training emphasis reportedly centers on reinforcement learning conducted in complex real-world environments spanning hundreds of thousands of machines, with the stated goal of producing efficient inference behavior and well-decomposed task plans that hold up under long agentic trajectories. In practice this means M2.5 is tuned less for casual chat and more for multi-step tool use, structured outputs, and code generation tasks that benefit from a large context window and stable reasoning across many turns. The model is distributed through several enterprise-grade channels, including an official NVIDIA NIM container on the NGC catalog under the minimax-ai organization and availability on Amazon Bedrock, so teams can choose between cloud-hosted inference and on-premises deployment depending on latency, cost, and data-residency needs.

The Latent Space AINews roundup dated February 13, 2026 explicitly names MiniMax M2.5 and reports a claimed 80.2% score on SWE-Bench Verified, framed as matching Opus-level performance. This is the only candidate in the set that supplies a concrete technical data point for the M2.5 model, and the only piece of evidence The M2.5 mention is bundled into a broader news roundup led by Gemini 3 Deep Think, Anthropic's reported $30B raise at a $380B valuation, and GPT-5.3-Codex Spark, so M2.5 detail is limited to a single paragraph with no parameter count, context window, pricing, or tooling specifics.
