OpenAI is upgrading its professional AI model to ChatGPT-5.4

Following an update to how ChatGPT models react to users, OpenAI is rolling out an even newer version to cater to complex problems with ChatGPT-5.4.

Just a couple of days prior to OpenAI’s recent release, the company announced a change to its Instant model. The chatbot meant for quick answers and more conversational flow got an update to its ability to, well, converse.

Following that behavioral change, the company has tagged on an additional release. OpenAI made ChatGPT-5.4 official, marking it as an upgrade for users who need the model for “professional” work and for those who need more performance on complex tasks. Those models will be available as ChatGPT-5.4 Thinking and Pro, respectively.

OpenAI says the ChatGPT-5.4 Thinking model allows users to make changes during its thinking process. The response will start with a plan of action, so users have a chance to alter course if necessary. The model also gets improvements to deep web research without losing context for other conversational elements. It seems like the AI company is positioning the Thinking version as its main model.

The company is also aiming the Thinking model at those who need more from an AI model when creating spreadsheets, presentations, and other documents. The model supposedly operates much better than ChatGPT-5.2, from scoring 68.4% to 87.3%.

Another point of interest is ChatGPT-5.4’s ability to use computers. The press release notes that the new model is “excellent at writing code to operate computers via libraries like Playwright, as well as issuing mouse and keyboard commands in response to screenshots.”

OpenAI notes that ChatGPT-5.4 is rolling out gradually, starting today. The Thinking model is available for Plus, Team, and Pro users, while the Pro variant is only available for Pro and Enterprise plans. Free users don’t seem to be included, for now.
