GPT-5.4 and GPT-5.4 Pro were introduced by OpenAI on March 5, 2026, as their most advanced and efficient frontier models designed for professional knowledge work, reasoning, and coding.

Key highlights of the models include:

• Native Computer-Use: GPT-5.4 is OpenAI's first general-purpose model with native computer-use capabilities, enabling it to operate applications and desktop environments using screenshots, mouse/keyboard commands, and code libraries like Playwright. It supports a massive 1 million token context window.
• Enhanced Tool Search: A new tool search feature reduces token costs by only appending tool definitions to the context when the model specifically needs them, which makes agentic workflows faster and more affordable.
• Interactive Reasoning: In ChatGPT, GPT-5.4 Thinking now provides an upfront outline of its planned approach, allowing users to adjust the model's course mid-response to better align with their goals.
• Benchmark Dominance: GPT-5.4 sets new state-of-the-art scores across multiple evaluations, outperforming predecessors like GPT-5.2 and GPT-5.3-Codex in complex knowledge work (GDPval), computer navigation (OSWorld-Verified), and coding tasks (SWE-Bench Pro).
