OpenAI has unveiled its new GPT model, described as “our most capable and efficient frontier model for professional work,” combining the company’s advancements in reasoning, coding, and agentic workflows into a single unified model.
GPT-5.4 was released on Thursday, March 6, 2026, and is now available for apply in ChatGPT, Codex, and through the OpenAI API. GPT-5.4 Thinking will be rolled out to Plus, Teams, and Pro users, while GPT-5.4 Pro will be accessible via the API, as well as to ChatGPT Enterprise and Edu subscribers.
According to OpenAI, GPT-5.4 is the first general-purpose model the company has released with native computer use capabilities, meaning it can operate autonomously within various applications on a computer on behalf of the user. This development signals a growing trend toward AI-powered automation of complex digital tasks.
OpenAI specified that the model can write code to operate and execute tasks on computers, as well as issue keyboard and mouse commands to navigate the operating system.
GPT-5.4 Launch Arrives During a Sensitive Period for OpenAI
Regarding more general uses, such as answering questions, OpenAI claims the newest model also delivers improved results in that area. The company asserts that individual responses generated by GPT-5.4 are 33% less likely to contain errors compared to responses from GPT-5.2, and the new model is 18% less likely to make mistakes overall.
The company also stated that “hallucinations” are less likely to occur with GPT-5.4, although it did not provide a specific percentage for this improvement.
The launch comes after ChatGPT experienced a loss of approximately 1.5 million users amid a boycott in the United States.
This followed OpenAI’s announcement that it would work with the Pentagon after rival company Anthropic requested assurances that the models it provided would not be used for surveillance of Americans or fully autonomous weapons systems.
The Pentagon declined the request, and the Trump administration banned the use of Anthropic’s models, the company behind the Claude chatbot, in any branch of the federal government.
