You can now access GPT-5, GPT-5-mini, and GPT-5-nano by OpenAI, models designed to push the frontier of reasoning and domain expertise, using Vercel's AI Gateway with no other provider accounts required.
AI Gateway lets you call the model with a consistent unified API and just a single string update, track usage and cost, and configure performance optimizations, retries, and failover for higher than provider-average uptime.
To use it with the AI SDK v5, start by installing the package:
pnpm i ai
Then set the model to either openai/gpt-5 or openai/gpt-5-mini or openai/gpt-5-nano:
import { streamText } from 'ai'
const result = streamText({
model: "openai/gpt-5", // or openai/gpt-5-mini or openai/gpt-5-nano
prompt: "Generate an ansi animation of sutro tower"
})
Includes built-in observability, Bring Your Own Key support, and intelligent provider routing with automatic retries.
