GPT 5.4
OpenAI's most capable and efficient frontier model for professional work, combining powerful reasoning with reliable agentic execution at scale.
OpenAI Agentic reasoning with a 1M token context
GPT-5.4 is a text generation model developed by OpenAI, released in March 2026 as their flagship model for professional and enterprise use. It is available in three variants — standard, Thinking, and Pro — and features a context window of 1 million tokens, the largest OpenAI has offered. The model is designed not only to plan complex tasks but to complete them reliably, with built-in computer use capabilities for orchestrating multi-step agentic workflows.
GPT-5.4 is best suited for enterprise teams running AI in production environments, including customer support automation, document drafting, data analysis, and developer workflows. It recorded an 83% score on GDPval for knowledge work tasks and ranked second out of 116 models on the Artificial Analysis Intelligence Index. The Pro variant adds multi-path reasoning evaluation for scenarios where analytical depth is prioritized over speed, such as scientific research and complex decision-making.
What GPT 5.4 supports
Agentic Workflows
Executes multi-step tasks autonomously using built-in computer use capabilities, including tool orchestration, file access, and data extraction with minimal human oversight.
1M Token Context
Supports a context window of up to 1 million tokens, enabling processing of extensive documents, large codebases, and long multi-turn sessions in a single request.
Extended Reasoning
The Thinking variant applies enhanced logical follow-through across long, complex interactions, maintaining consistency over extended reasoning chains.
Artifact Generation
Produces structured professional outputs including documents, spreadsheets, slide decks, financial models, and legal analyses in a single session.
Reduced Hallucinations
Delivers 33% fewer factual errors in individual claims compared to GPT-5.2, according to OpenAI's internal benchmarks.
Token-Efficient Output
Solves problems using fewer tokens than its predecessor, reducing latency and cost for high-volume production workloads.
Code Generation
Generates, reviews, and debugs code across common programming languages, with support for developer workflows within the full 1M token context.
Deep Analytical Reasoning
The Pro variant uses multi-path reasoning evaluation to provide greater analytical depth for research, legal analysis, and complex decision-making tasks.
