Vercel AI SDK

Name: Vercel AI SDK
Author: Vercel

by VercelFramework / SDKai-sdk.dev

The Vercel AI SDK is the default TypeScript toolkit for building AI features, and Opper publishes a provider for it. Install @opperai/ai-sdk-provider, set OPPER_API_KEY, and every generateText, streamText and tool call routes through the gateway, so switching model means editing a string rather than rewriting a client. Wrap a model with opperSpan and every call in a session lands under one span in tracing.
