OpenAI has released GPT-5.4, a new AI model the company says is its most capable system to date for professional use. The model combines advanced reasoning, coding, and the ability to autonomously operate computers and software, turning up the heat in the competition for enterprise customers that has been Anthropic’s stronghold.
The new model consolidates some of the capabilities that OpenAI had previously spread across separate models, bringing together the coding strengths of GPT-5.3-Codex—the company’s leading programming model—improved reasoning skills, and the agentic ability for the model to navigate desktops, browsers, and software applications autonomously.
