OpenAI has launched a new AI model called GPT 5.4, which the company claims is its most ‘capable and efficient frontier model’ yet for professional work. The model is rolling out across ChatGPT, the API, and OpenAI Codex. Alongside it, OpenAI has also introduced GPT 5.4 Pro in ChatGPT and the API, a version designed for users who want the highest level of performance when working on complex tasks.
According to the AI giant, GPT 5.4 combines the company’s latest advances in reasoning, coding and agentic workflows into a single model. It builds on the strong coding abilities of GPT 5.3 Codex while improving how the AI interacts with different tools, software environments, and professional tasks.

OpenAI also claims that the new model can complete complicated tasks with greater accuracy and efficiency, delivering what users asked for with less back and forth.
In ChatGPT, the new model appears as GPT 5.4 Thinking and lets users see an early outline of how the AI plans to approach a task. By showing this plan before the final response is completed, users can review it and adjust the direction if needed while the model is still working. OpenAI says this helps users guide the AI more easily and get outputs that better match their expectations.

The company also claims the model improves deep web research, especially for very specific queries. ‘GPT 5.4 Thinking also improves deep web research, particularly for highly specific queries, while better maintaining context for questions that require longer thinking. Together, these improvements mean higher-quality answers that arrive faster and stay relevant to the task at hand,’ OpenAI explains.
For developers using the API or Codex, GPT 5.4 introduces native computer-use abilities. This allows AI agents to interact directly with computers and perform workflows across multiple applications. The model also supports up to 1 million tokens of context.
OpenAI says GPT 5.4 is its ‘most token efficient reasoning model’ so far, using significantly fewer tokens compared to GPT 5.2.
‘Together with advances in general reasoning, coding, and professional knowledge work, GPT 5.4 enables more reliable agents, faster developer workflows, and higher-quality outputs across ChatGPT, the API, and Codex,’ OpenAI said.
