AI SDK
Unified model interface for JavaScript applications
- Open source
- Agent Frameworks
What it is
The AI SDK gives JavaScript and TypeScript applications a single interface across model providers, covering text generation, structured output, tool calling and embeddings. Its streaming primitives and React hooks are built for token-by-token UI updates and server-driven rendering. Changing provider is a change of adapter rather than a rewrite of every call site.
Best for
Web applications that need streaming AI interfaces today and the freedom to swap model providers later.
Where it falls short
It is an application-layer SDK, not an orchestration runtime — durable state for long-running agents is still something you have to add.
Characteristics
- javascript
- streaming
- tool-calling
- provider-agnostic
