GPT 5.4 is now on AI Gateway
By Steven Van ·
GPT-5.4 and GPT-5.4 Pro bring GPT-5.3-Codex's agentic gains beyond coding to reports, spreadsheets, and other knowledge work.
Vercel's AI Gateway now offers OpenAI's GPT-5.4 and GPT-5.4 Pro. The model brings the agentic and reasoning improvements from GPT-5.3-Codex to domains beyond coding, including knowledge work like reports, spreadsheets, presentations, and analysis, and handles complex multi-step workflows involving tools, research, and multiple sources more reliably.
GPT-5.4 is faster and more token-efficient than GPT-5.2. GPT-5.4 Pro is for developers who need maximum performance on the most complex tasks. To use either model, set model to "openai/gpt-5.4" or "openai/gpt-5.4-pro" in the AI SDK.
