GPT-5.4 Pro is OpenAI's most advanced model. It is built on the unified architecture of GPT-5.4, with stronger reasoning capabilities, enabling it to handle complex and high-risk tasks. This model has a context window of over 1 million tokens (922,000 for input and 128,000 for output) and supports both text and image inputs. GPT-5.4 Pro has been optimized for step-by-step reasoning, instruction following, and accuracy, and excels in agent coding, long-context workflows, and multi-step problem solving.
GPT-5.4 is OpenAI's latest cutting-edge large model, which integrates the Codex series and the GPT series into a unified system. The model has a context window of over 1 million tokens (922,000 input tokens and 128,000 output tokens), supports text and image inputs, and can perform high-context reasoning, coding, and multimodal analysis within the same workflow. The model delivers improved performance in coding, document understanding, tool usage, and instruction execution. It is designed as a robust choice for both general-purpose tasks and software engineering scenarios, capable of generating production-grade code, integrating information from multiple sources, and executing complex multi-step workflows with fewer iterations and higher token efficiency.
