GPT 5.4 is now on AI Gateway
GPT-5.4 is now available on AI Gateway.This model brings the agentic and reasoning leaps from GPT-5.3-Codex to all domains.
Academic or research source. Check the methodology, sample size, and whether it's been replicated.
Key Takeaways
- This includes knowledge work like reports, spreadsheets, presentations, and analysis in addition to coding.
- It handles complex multi-step workflows more reliably, including tasks that involve tools, research, and pulling from multiple sources.
- GPT-5.4 is faster and also more token-efficient than previous iterations (GPT-5.2).To use this model, set model to openai/gpt-5.4 in the AI SDK.AI Gateway provides a unified API for calling models,…

GPT-5.4 is faster and also more token-efficient than previous iterations (GPT-5.2).To use this model, set model to openai/gpt-5.4 in the AI SDK.AI Gateway provides a unified API for calling models, tracking usage and cost, and configuring retries, failover, and performance optimizations for higher-than-provider uptime. It includes built-in observability, Bring Your Own Key support, and intelligent provider routing with automatic retries.Learn more about AI Gateway, view the AI Gateway model leaderboard or try it in Vercel Blog's model playground.
