Chat model · OpenAI ·
GPT-5.4 is a chat model by OpenAI. In Endless it costs 303.8 credits per 1M input tokens and 1518.8 per 1M output tokens, on every plan.
GPT-5.4 is OpenAI's March 2026 model for coding and professional work, and the first OpenAI general-purpose model with native computer use.
GPT-5.4 launched on March 5, 2026, as OpenAI's most capable model for professional work at the time. It was the company's first general-purpose model with native computer use, and it introduced tool search, which lets the model load only the tool definitions it needs instead of all of them up front. It accepts text and images, supports a 1.05M-token context window and can write up to 128K tokens in one response.
It works well for detailed written work: long explanations, structured reports, technical documentation and code that comes with comments walking through the logic. It supports reasoning effort from none to xhigh, which covers direct answers as well as problems that need more thought.
GPT-5.4 predates OpenAI's GPT-5.6 and GPT-6 families. Among the newer models, GPT-6.1 Sol handles complex coding at a balanced cost and GPT-6 Astra is the most capable. GPT-5.4 stays available in the same workspace when you want consistent results from a model your team already knows.
