- OpenAI Releases GPT 5.5 for Coding, Enterprise Work
OpenAI on Thursday released GPT-5.5, calling it its “smartest and most intuitive” model yet, as the ChatGPT maker pushes further into coding, knowledge work and agentic AI.
The company said GPT-5.5 is designed for complex tasks that require reasoning across context and sustained action over time, including writing and debugging code, online research, data analysis, document creation, spreadsheet work and software use.
OpenAI said the model can handle messy, multi-part tasks by planning, using tools, checking its work and moving across applications with less step-by-step instruction from users.
GPT-5.5 is rolling out to Plus, Pro, Business and Enterprise users in ChatGPT and Codex. GPT-5.5 Pro is being made available to Pro, Business and Enterprise users in ChatGPT, with API access expected soon.
OpenAI said GPT-5.5 is its strongest agentic coding model so far. The company said the model scored 82.7% on Terminal-Bench 2.0, which tests complex command-line workflows, and 58.6% on SWE-Bench Pro, which evaluates real-world GitHub issue resolution.
It also said GPT-5.5 uses fewer tokens than GPT-5.4 for most Codex users while delivering better results.
The model also showed gains in knowledge work and scientific research, according to OpenAI.
It scored 84.9% on GDPval, a benchmark for professional knowledge work across 44 occupations, and 78.7% on OSWorld-Verified, which measures whether a model can operate real computer environments.
OpenAI said GPT-5.5 also improved over GPT-5.4 on GeneBench, a benchmark for multi-stage scientific data analysis in genetics and quantitative biology.
OpenAI President Greg Brockman described the release as a step toward more agentic and intuitive computing.
“This model is a real step forward toward the computing we expect in the future,” he told reporters, according to TechCrunch. “Still, it’s just one step, and we anticipate many more.”
The launch comes as OpenAI and rivals including Anthropic compete more aggressively in coding, enterprise AI and computer-use tools.
The Verge reported that GPT-5.5 follows last month’s GPT-5.4 release and comes as both companies push deeper into AI models for software development and business workflows.
