Executive Summary
A new model, GPT-5.4, is now available on the AI Gateway platform, extending advanced agentic and reasoning capabilities beyond coding to all knowledge work domains. This iteration is designed to more reliably handle complex, multi-step workflows that involve tools, research, and multiple data sources. Compared to previous versions like GPT-5.2, GPT-5.4 is faster and more token-efficient, enabling more sophisticated automation for professional tasks.
Key Takeaways
* Product: GPT-5.4
* Availability: Immediately available on AI Gateway.
* Core Improvement: Extends the advanced agentic and reasoning capabilities previously seen in coding-specific models (like GPT-5.3-Codex) to general knowledge work, including reports, spreadsheets, and analysis.
* Key Capabilities: Reliably executes complex, multi-step workflows involving tools, research, and information from multiple sources.
* Performance: Faster and more token-efficient than previous iterations (e.g., GPT-5.2).
* Implementation: Developers can access the model by specifying `openai/gpt-5.4` in the AI SDK.
Strategic Importance
This launch signals a shift towards models capable of autonomous, multi-step task execution, positioning GPT-5.4 as a powerful tool for automating complex professional and enterprise workflows.
