## AI overview

Vercel AI Gateway now supports OpenAI's GPT-5.4 Mini and GPT-5.4 Nano models. The models target coding, computer-use, tool orchestration, browser interactions, and sub-agent workflows, with controls for verbosity and reasoning levels. GPT-5.4 Nano offers similar evaluation performance to Mini at a lower price for high-volume workloads.

## Source excerpt

GPT-5.4 Mini and GPT-5.4 Nano from OpenAI are now available on Vercel AI Gateway. Both models deliver state-of-the-art performance for their size class in coding and computer use, and are built for sub-agent workflows where multiple smaller models coordinate on parts of a larger task. The models also support the verbosity and reasoning level parameters, giving you control over response detail and how much the model reasons before answering. GPT-5.4 Mini GPT-5.4 Mini handles code generation, tool orchestration, and multi-step browser interactions more reliably than previous mini-tier models. It's a strong default for agentic tasks that need to balance capability and cost. To use this model, set model to openai/gpt-5.4-mini in the AI SDK. GPT-5.4 Nano GPT-5.4 Nano performs close to GPT-5.4 Mini in evaluations at a lower price point. The model is well-suited for high-volume use cases like sub-agent workflows where cost scales with the number of parallel calls. To use this model, set model to openai/gpt-5.4-nano 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.
