Description

Composer 2 is a high-performance AI coding model available within Cursor, built to handle complex programming tasks with improved accuracy and efficiency. It is trained through advanced pretraining and reinforcement learning, allowing it to solve long-horizon coding problems that involve multiple steps and decisions. The model shows significant improvements across major benchmarks such as Terminal-Bench and SWE-bench Multilingual, reflecting its strong real-world coding capabilities. It delivers faster performance while maintaining high-quality outputs, making it suitable for demanding development workflows. Composer 2 is designed to balance intelligence and cost, offering competitive pricing compared to other frontier models. It also includes a faster variant that provides the same level of intelligence with optimized speed for time-sensitive tasks. The model is integrated directly into the Cursor platform, enabling seamless use within development environments. Its ability to handle complex coding scenarios makes it valuable for both individual developers and teams. Overall, Composer 2 enhances productivity by automating and accelerating software development tasks.

Description

Cognition has unveiled SWE-1.5, the newest agent-model specifically designed for software engineering, featuring an expansive "frontier-size" architecture composed of hundreds of billions of parameters and an end-to-end optimization (encompassing the model, inference engine, and agent harness) that enhances both speed and intelligence. This model showcases nearly state-of-the-art coding capabilities and establishes a new standard for latency, achieving inference speeds of up to 950 tokens per second, which is approximately six times quicker than its predecessor, Haiku 4.5, and thirteen times faster than Sonnet 4.5. Trained through extensive reinforcement learning in realistic coding-agent environments that incorporate multi-turn workflows, unit tests, and quality assessments, SWE-1.5 also leverages integrated software tools and high-performance hardware, including thousands of GB200 NVL72 chips paired with a custom hypervisor infrastructure. Furthermore, its innovative architecture allows for more effective handling of complex coding tasks and improves overall productivity for software development teams. This combination of speed, efficiency, and intelligent design positions SWE-1.5 as a game changer in the realm of coding models.
