Frequently Asked Questions

What makes GPT-5.4 more efficient than GPT-5.2?

GPT-5.4 uses significantly fewer tokens to solve problems, leading to reduced token costs and faster response speeds while maintaining high intelligence.

Can GPT-5.4 control computers without relying on separate models?

Yes, GPT-5.4 has state-of-the-art native computer-use capabilities, allowing it to directly operate computers using screenshots and keyboard/mouse commands.

How does the 1M context window work in GPT-5.4?

GPT-5.4 supports an experimental 1 million token context window, enabling agents to plan and execute tasks over long horizons, though usage beyond standard limits may incur higher costs.

What is Tool Search and how does it benefit developers?

Tool Search is a new system that allows GPT-5.4 to dynamically look up tool definitions as needed, reducing token consumption and speeding up requests in environments with many available tools.
