SWE-1.5 vs. MiniMax M2.5

Cognition has introduced SWE-1.5, the latest agent-model tailored for software engineering, which boasts an extensive "frontier-size" architecture comprising hundreds of billions of parameters alongside a comprehensive end-to-end optimization that enhances both its speed and intelligence. This advanced model nearly reaches state-of-the-art coding capabilities and sets a new benchmark for latency, achieving inference speeds of up to 950 tokens per second, which is nearly six times the speed of its forerunner, Haiku 4.5, and thirteen times faster than Sonnet 4.5. Developed through rigorous reinforcement learning in realistic coding-agent environments that entail multi-turn workflows, unit tests, and quality evaluations, SWE-1.5 utilizes integrated software tools and high-performance hardware, including thousands of GB200 NVL72 chips coupled with a bespoke hypervisor infrastructure. Its innovative design facilitates more efficient management of intricate coding challenges and significantly boosts productivity for software development teams. With its combination of rapid performance, efficiency, and smart engineering, SWE-1.5 is set to revolutionize the coding model landscape and help developers tackle their tasks more effectively. The potential impact of this model on the future of software engineering practices cannot be overstated.

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.
