OpenAI launches GPT-5.4 with 1 million token context

OpenAI has released GPT-5.4, described as the company's most capable and efficient frontier model. The model features state-of-the-art performance in coding, computer use, tool search and a context window of 1 million tokens.

WHY IT MATTERS

A million token context enables handling of significantly larger document volumes and more complex tasks in a single pass. This represents a substantial step forward in how much information frontier models can process simultaneously.
