Introducing GPT-5.4
OpenAI's new frontier model features state-of-the-art coding, tool search, and a massive 1M-token context window.
OpenAI has officially unveiled GPT-5.4, positioning it as the company's most advanced and efficient frontier model designed specifically for professional applications. The announcement highlights major leaps in core capabilities like coding, computer use, and tool search, alongside a massive 1-million-token context window. This release marks a significant step in OpenAI's strategy to create AI systems that can handle complex, multi-step professional tasks with greater autonomy and reliability, moving beyond simple chat interfaces to more integrated agentic workflows.
The technical cornerstone of GPT-5.4 is its 1M-token context, which allows it to process and reason over documents equivalent to hundreds of pages of text in a single session. This, combined with enhanced 'computer use' and 'tool search' abilities, means the model can more effectively navigate software interfaces, execute commands, and find and utilize the right external tools or APIs to complete a job. For developers and enterprises, this translates to more powerful AI agents capable of automating intricate workflows, from deep codebase analysis and refactoring to managing complex data pipelines, all while maintaining coherence over extremely long interactions.
- Features a massive 1-million-token context window for processing long documents and complex tasks
- Excels in state-of-the-art coding, computer use (UI interaction), and tool search capabilities
- Positioned as OpenAI's most efficient frontier model for professional and agentic workflows
