OpenAI has released GPT-5.5, their most intelligent and intuitive model yet, designed to handle complex work tasks autonomously. The new model excels at coding, debugging, data analysis, and document creation while requiring less user oversight for multi-step processes.

GPT-5.5 delivers state-of-the-art performance on coding benchmarks, achieving 82.7% accuracy on Terminal-Bench 2.0 and 58.6% on SWE-Bench Pro. Early testers report significant improvements in reasoning and autonomy, with NVIDIA engineers calling it indispensable for complex development work.

The model is now available to Plus, Pro, Business, and Enterprise users in ChatGPT and Codex. OpenAI teams are already using it for tasks like analyzing speaking request data and reviewing tax forms, demonstrating how GPT-5.5 is transforming real-world workflows across multiple domains.
