gpt-5.4, and Codex. It unifies advanced reasoning with GPT-5.3-Codex's coding strength and native computer-use — OpenAI's first general-purpose model that operates computers, clicks through interfaces, and runs multi-step workflows across apps. It supports 1M tokens of context, introduces tool search that cuts token usage 47% in tool-heavy workflows, and is 33% less likely to produce false claims versus GPT-5.2. GPT-5.4 Thinking shows an upfront plan and lets you adjust direction mid-response.Having computer use, coding, and deep reasoning in one model removes the friction of stitching separate vision models and agents together. Teams building agentic workflows get a single model that handles planning, execution, and UI interaction.
GPT-5.4 Thinking rolls out now to ChatGPT Plus, Team, and Pro users, replacing GPT-5.2 Thinking. In the API, use gpt-5.4 ($2.50/M input tokens) or gpt-5.4-pro ($30/M input tokens).
GPT-5.4 Thinking and GPT-5.4 Pro are rolling out now in ChatGPT. GPT-5.4 is also now available in the API and Codex. GPT-5.4 brings our advances in reasoning, coding, and agentic workflows into one frontier model. https://t.co/1hy6xXLAmJ
