GPT-5.5 by OpenAI

GPT-5.5 represents the forefront of advanced computational models, engineered for enhanced autonomy, speed, and efficiency in real-world applications. Its core strengths include: * Advanced code composition and debugging * Comprehensive research capabilities * Data interpretation and analysis * Multi-step task execution with minimal oversight * Seamless integration and operation across various digital tools This model is designed to intuitively understand user intent, allowing it to undertake and complete complex, multi-part tasks by planning, utilizing relevant tools, and iteratively refining its approach. It significantly improves upon previous versions by handling greater portions of work independently, reducing the need for constant supervision and detailed step-by-step instructions. The gains in performance are particularly notable in areas requiring extensive reasoning and action over time, such as agentic coding, computer interaction, knowledge work, and early-stage scientific inquiry. Despite its increased capabilities, GPT-5.5 maintains per-token latency comparable to its predecessors, ensuring that enhanced performance does not come at the cost of speed. Additionally, it optimizes resource usage by requiring fewer tokens for completing tasks, making it both more powerful and more efficient. GPT-5.5 is ideal for engineers, researchers, data scientists, and business professionals seeking a powerful partner for complex, multi-step projects. It is currently available to Plus, Pro, Business, and Enterprise users.
