OpenAI Announces GPT-5.4 with Enhanced Coding and 1M-Token Context

According to OpenAI, the company has introduced GPT-5.4, which it describes as its “most capable and efficient frontier model for professional work.”

The new model features several key capabilities, as stated in OpenAI’s announcement:

• State-of-the-art coding performance
• Computer use functionality
• Tool search capabilities
• 1 million-token context window

OpenAI positions GPT-5.4 as specifically designed for professional work applications, suggesting a focus on enterprise and productivity use cases. The expanded context window of 1 million tokens represents a significant increase from previous models, potentially allowing users to process substantially larger documents or codebases in a single interaction.

The inclusion of “computer use” as a stated feature suggests the model may have capabilities for interacting with computer interfaces, though OpenAI’s announcement does not provide additional detail on this functionality.

No information was provided in the source material regarding availability, pricing, or specific benchmark results for the model.
