GPT-5.4 is OpenAI’s __frontier model__, released in March 2026, that brings together OpenAI’s advances in reasoning, code and agentic workflows into one product. With a __1 million token__ context, native __computer-use__ capabilities and improved efficiency, GPT-5.4 powers ChatGPT (Thinking, Pro) and the OpenAI API. The model reduces false claims by 33% and errors in responses by 18%, while consuming fewer tokens than GPT-5.2.
What is GPT-5.4?
GPT-5.4 is OpenAI’s latest frontier model, presented on March 5, 2026. The model unites recent advances in reasoning, code and agentic workflows into a single product available through ChatGPT (Plus, Pro, Team, Enterprise) and the OpenAI API. GPT-5.4 supports 1 million token context and includes native computer-use capabilities. Multiple variants are available: Thinking and Pro for the most complex tasks, mini for common use (including the free plan), and nano for high-throughput API integrations. The model aims to reduce hallucinations, speed up response times and improve reliability in agents.
Key Features
At the heart of GPT-5.4: 1 million token context, which allows analyzing very long documents, managing long conversation histories and coordinating multi-step workflows. The model also includes native computer-use capabilities, meaning the ability to act on a computer (click, type, open applications) to accomplish a task. GPT-5.4 improves code, science, research and office tasks. Token consumption is more efficient than GPT-5.2: for the same result, the model uses significantly fewer tokens. Claims are 33% less likely to be false, and responses 18% less likely to include an error. Multiple variants are made available to calibrate the speed/quality tradeoff.
Use Cases
The first use cases concern developers who want to generate, refactor and test code at scale. Thinking mode is particularly useful for complex issues (architecture, debugging, stack choices). Product teams use it for internal documentation, technical writing and feature design. Start-ups building AI agents exploit computer-use capabilities to automate complex business tasks (finance, HR, operations). Researchers and analysts use extended context to summarize and cross long corpora. Finally, consultants and professional services integrate GPT-5.4 into critical workflows to increase deliverable quality.
Advantages
The main benefit is the rare combination of reasoning, code and computer-use in one model. The second benefit is efficiency: fewer tokens consumed means lower cost and faster response times at equal quality. The third is reliability: reduced errors and hallucinations make GPT-5.4 more usable in production. The fourth benefit is flexibility: the Thinking, Pro, mini and nano variants allow adapting the model to the use case without changing ecosystems. Finally, integration with ChatGPT and the OpenAI API facilitates deployment in products or internal workflows.
Pricing
GPT-5.4 is available in ChatGPT Plus ($20 per month), Team, Pro and Enterprise for self-service users. Free users access GPT-5.4 mini. On the API side, OpenAI offers token-based pricing with different tiers depending on the variant (Thinking, Pro, mini, nano). Prices are designed to make usage economically viable even at high volume, with optimizations possible via prompt caching or batching. Enterprise commitments allow obtaining preferred rates for large-scale projects.
Conclusion
GPT-5.4 illustrates the growing maturity of frontier models: more efficient, more reliable and more capable of acting on the world through computer-use. For developers and organizations engaged in serious AI projects, the model represents a robust reference that should be quickly integrated into team daily work.
