GPT-5.4

GPT-5.4 is the most capable AI model from OpenAI, built for advanced real-world tasks across coding, computer use, deep research, complex document understanding, and multi-step problem solving. It outperforms previous versions on agentic workflows and tool use, delivering stronger reasoning, higher accuracy, and more reliable results on complex tasks. Optional parameters: Set reasoning effort: Select from `low`, `medium`, `high`, `xhigh`. No reasoning effort by default. Set web search and real-time information access: toggle it `on`, otherwise it is `off` by default. Set verbosity to control response details at the end of your message: Select from `low`, `medium`, `high`. This is set to `medium` by default.
