About GPT-5.4
GPT-5.4 is OpenAI's first mainline reasoning model that integrates the frontier coding capabilities of GPT-5.3-Codex into the general-purpose model series, rolling out across ChatGPT, the API, and Codex simultaneously. It combines advances in reasoning, agentic tool use, and software engineering into a single model, with experimental support for a 1M token context window in Codex. It is positioned as the convergence point of OpenAI's coding and reasoning lines, suited for complex multi-domain professional tasks that require both deep reasoning and reliable code execution.
