GPT-5.4 is OpenAI's latest frontier model released in March 2026, unifying the Codex and GPT product lines into a single system. It features a 1M+ token context window, native computer-use capabilities, and industry-leading coding performance inherited from GPT-5.3-Codex. The model is significantly more token-efficient than GPT-5.2, and achieves state-of-the-art results on knowledge work benchmarks, matching or exceeding industry professionals in 83% of comparisons across 44 occupations. It excels at agentic coding, document understanding, tool use, and complex multi-step workflows.
