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

GPT-5.6 Sol is OpenAI’s flagship model in the GPT-5.6 series, built for high-end reasoning, coding, scientific analysis, cybersecurity, and agentic automation. The model is designed to handle complex tasks that require planning, iteration, tool coordination, long-horizon reasoning, and careful execution across multiple steps. GPT-5.6 Sol introduces max reasoning effort, giving the model more time to reason deeply through difficult problems. It also introduces ultra mode, which uses subagents to accelerate complex work and extend capability beyond a single-agent workflow. For coding, GPT-5.6 Sol is positioned for command-line workflows, software engineering tasks, debugging, testing, and multi-step tool use. In biology and quantitative research workflows, the model is designed to support genomics analysis and other long-context scientific tasks while using tokens more efficiently than prior models. For cybersecurity, GPT-5.6 Sol supports legitimate defensive work such as vulnerability research, code review, patch development, security education, and defensive testing. The model includes a layered safeguard stack with trained refusals, real-time cyber and biology misuse classifiers, account-level monitoring, differentiated access, human-in-the-loop review, and ongoing red-team testing. GPT-5.6 Sol helps trusted users and organizations access more powerful AI for technical work while maintaining stronger controls around misuse, sensitive requests, and high-risk activity.
