OpenAI on Thursday introduced GPT-5.4, a new flagship artificial intelligence model rolling out across ChatGPT, the company’s API and Codex as it pushes further into workplace software, coding and software agents. In ChatGPT, the release appears as GPT-5.4 Thinking, while a higher-performance GPT-5.4 Pro version is being offered for more demanding tasks.
The company said GPT-5.4 is aimed at professional work and combines improvements in reasoning, coding and multi-step automated workflows. OpenAI said the model is better suited for tasks involving spreadsheets, presentations and documents, and that in ChatGPT it can now present an upfront plan for longer requests so users can redirect the response while it is still being generated. The company also said the model improves web research for highly specific queries and keeps context better during longer tasks.
