Vercel default serverless function duration limit
By default, Vercel serverless functions have a maximum duration of 10 seconds on the Hobby Tier. This limit can be increased to 60 seconds on the Hobby Tier using route segment config.

Set Vercel function maximum duration with route segment config
To update the maximum duration of a Vercel function, add the route segment config export const maxDuration = 30; to the top of your route handler or the page which is calling your server action. This value is specified in seconds.
Forward abortSignal to streamText for request cancellation
To propagate request cancellation from AI SDK UI helpers like useChat to a Vercel Function and its model request, forward the route's req.signal to streamText or generateText as the abortSignal parameter.
Enable supportsCancellation in vercel.json for request cancellation
To support request cancellation in Vercel Functions, enable supportsCancellation in vercel.json for the specific route. This must be configured alongside using the Node.js runtime (default for Next.js route handlers) and forwarding req.signal to streamText or generateText.
Example Vercel request cancellation configuration
Enable cancellation for a chat route by adding this to vercel.json: ```json { "functions": { "app/api/chat/route.ts": { "supportsCancellation": true } } } ```
Example forwarding request signal to streamText
To forward the request signal to streamText for cancellation support: ```ts import { convertToModelMessages, streamText, type UIMessage } from 'ai'; __PROVIDER_IMPORT__; export async function POST(req: Request) { const { messages }: { messages: UIMessage[] } = await req.json(); const result = streamText({ model: __MODEL__, messages: convertToModelMessages(messages), abortSignal: req.signal, }); return result.toUIMessageStreamResponse(); } ```
Effect of missing supportsCancellation on stop()
Without supportsCancellation enabled, calling stop() on AI SDK UI helpers closes the client-side stream but does not cancel the Vercel Function or model request. The server-side request continues running.
Add environment variables to Vercel deployment
To add environment variables like API keys to your Vercel production deployment, expand the Environment Variables section during project import and paste in your .env.local file. Vercel will automatically parse the variables and enter them in key:value format.
