Key point
GPT-5.4 and GPT-5.4 Pro models have launched on AI Gateway, offering enhanced reasoning and agentic capabilities.
Details
GPT-5.4 and GPT-5.4 Pro models have been newly added to AI Gateway.
These new models extend the agentic and reasoning capabilities proven in GPT-5.3-Codex beyond coding to every domain, including report writing, spreadsheets, presentations, and data analysis. In particular, they handle complex multi-step workflows involving tool use, research, and multiple sources more reliably.
Key features are as follows:
- Performance and Efficiency: Faster and more token-efficient compared to the previous version, GPT-5.2.
- GPT-5.4 Pro: Designed for developers who need maximum performance on the most complex tasks.
- AI Gateway Features: Supports a unified API, usage and cost tracking, retries and failover, observability, and intelligent provider routing.
Users can access the models in the AI SDK by setting them as openai/gpt-5.4 or openai/gpt-5.4-pro.
