MiniMax M2.5 vs. Claude Sonnet 5

MiniMax M2.5 is an advanced frontier model designed to deliver real-world productivity across coding, search, agentic tool use, and high-value office tasks. Built on large-scale reinforcement learning across hundreds of thousands of structured environments, it achieves state-of-the-art results on benchmarks such as SWE-Bench Verified, Multi-SWE-Bench, and BrowseComp. The model demonstrates architect-level planning capabilities, decomposing system requirements before generating full-stack code across more than ten programming languages including Go, Python, Rust, TypeScript, and Java. It supports complex development lifecycles, from initial system design and environment setup to iterative feature development and comprehensive code review. With native serving speeds of up to 100 tokens per second, M2.5 significantly reduces task completion time compared to prior versions. Reinforcement learning enhancements improve token efficiency and reduce redundant reasoning rounds, making agentic workflows faster and more precise. The model is available in both M2.5 and M2.5-Lightning variants, offering identical intelligence with different throughput configurations. Its pricing structure dramatically undercuts other frontier models, enabling continuous deployment at a fraction of traditional costs. M2.5 is fully integrated into MiniMax Agent, where standardized Office Skills allow it to generate formatted Word documents, financial models in Excel, and presentation-ready PowerPoint decks. Users can also create reusable domain-specific “Experts” that combine industry frameworks with Office Skills for structured, professional outputs. Internally, MiniMax reports that M2.5 autonomously completes a significant portion of operational tasks, including a majority of newly committed code. By pairing scalable reinforcement learning, high-speed inference, and ultra-low cost, MiniMax M2.5 positions itself as a production-ready engine for complex agent-driven applications.

Claude Sonnet 5 is Anthropic’s most advanced frontier model, engineered for sustained reasoning and complex, multi-stage tasks. It is optimized for long-horizon coding, agentic systems, and intensive interaction with computers and software tools. Sonnet 5 achieves state-of-the-art performance on the SWE-bench Verified benchmark, reflecting its deep software engineering expertise. It also leads the OSWorld benchmark, which evaluates real-world computer use capabilities. One of its defining strengths is the ability to maintain focus and coherence for more than 30 hours on demanding workflows. The model introduces major improvements in tool execution, memory management, and large-context reasoning. These upgrades allow it to handle extended conversations, multi-agent coordination, and iterative problem solving. Sonnet 5 supports context editing and persistent memory tools to maintain continuity across sessions. It can also execute code and create files directly within Claude applications. The model demonstrates strong understanding across technical and professional domains, including law, finance, and science. Claude Sonnet 5 is deployed under AI Safety Level 3 standards. Built-in classifiers and safeguards reduce risks related to prompt injection and sensitive outputs.
