GPT-5.4
Our most capable and efficient frontier model for professional work.
About
OpenAI's most powerful frontier model directly controls your computer, processes 1 million tokens, and reasons about very long tasks. It is claimed to reduce errors by 33% and significantly improve code and document analysis
Details
GPT-5.4 is described as OpenAI's most powerful frontier model, designed to push the boundaries of AI capabilities with direct computer control, enabling it to interact with and manipulate user systems autonomously. It features a massive 1 million token context window, allowing it to process and reason over extremely long inputs such as extensive documents, codebases, or multi-step task sequences without losing coherence. This model excels in handling very long tasks through advanced reasoning, making it suitable for complex workflows that require sustained attention and multi-turn interactions.
