GPT-5.4: The Ultimate AI for Professional Work
GPT-5.4 is OpenAI’s frontier model built for advanced professional work. Available in ChatGPT, Codex and the API, it combines top-tier reasoning, coding, and agentic workflows.
This release introduces native, state-of-the-art computer-use capabilities with a massive 1M token context window. AI agents can now autonomously navigate applications and complex software ecosystems with ease.
Furthermore, its new tool search features dramatically reduce token usage, making operations much faster and cheaper.
Main Capabilities of GPT-5.4
GPT-5.4 introduces a series of capabilities designed to revolutionize professional workflows, coding and agentic automation.
Computer Use
GPT-5.4 is the first general-purpose model with native computer-use capabilities from OpenAI, enabling agents to operate software and navigate desktops. It seamlessly interprets screenshots and executes keyboard or mouse commands to automate complex tasks.
Coding
Combining the strengths of GPT-5.3-Codex with advanced reasoning, it delivers top-tier performance on complex programming tasks. Developers benefit from lower latency, a high-speed fast mode, and interactive visual debugging for web and Electron apps.
Tool Search
By dynamically searching for tool definitions only when needed, GPT-5.4 eliminates the need to load massive tool ecosystems upfront. This dramatically reduces token usage by up to 47%, resulting in much faster and cheaper requests.
Improved Web Search
GPT-5.4 conducts persistent, multi-round web searches to gather and synthesize information from diverse sources. It excels at deep research, effortlessly locating "needle-in-a-haystack" answers for highly specific queries while maintaining perfect context.

Questions and Answers
Who is GPT-5.4 built for?
GPT-5.4 combines top-tier reasoning, coding, and agentic workflows to handle complex, multi-step tasks efficiently. Whether you are coding, doing deep web research, or creating spreadsheets, it is built to deliver highly accurate results with less back-and-forth.
How does GPT-5.4 differ from previous models like GPT-5.2?
Unlike its predecessors, GPT-5.4 introduces native computer-use capabilities, meaning it can interact directly with desktop applications. It also features a massive 1M token context window and significantly reduced hallucination rates.
Can GPT-5.4 actually operate my computer?
Yes. GPT-5.4 is the first general-purpose model from OpenAI equipped with native computer-use abilities.
By interpreting screenshots and executing keyboard or mouse commands, it can navigate websites, automate data entry, and complete multi-step workflows across your software systems, acting as a highly capable digital assistant.
How does GPT-5.4 make using resources more efficient?
GPT-5.4 introduces a new “tool search” feature. Instead of loading every single tool definition into a prompt upfront, the model dynamically searches for and retrieves only the specific tools it needs for a given task, making requests faster and cheaper.
