What it does
A provider-agnostic TypeScript toolkit for building AI applications, chatbots, and agents with a unified interface to OpenAI, Anthropic, Google, and other LLM providers. The SDK abstracts provider differences behind a single API, letting you swap models or providers with a string change. It supports text generation, structured data extraction with Zod schemas, tool-calling agents, and streaming. Optional UI integration hooks for Next.js, React, Svelte, and Vue simplify building generative interfaces.
Who it's for
Full-stack and backend engineers building LLM-powered applications in TypeScript or Node.js. Ideal for teams that want to avoid vendor lock-in or experiment with multiple models under a consistent API, or who are integrating AI into existing Next.js/React applications.
Common use cases
- Building multi-model chatbots that can switch between OpenAI, Anthropic, and Google without code changes
- Creating AI agents with tool calling, memory, and streaming responses
- Extracting structured data (JSON) from unstructured text using Zod validation
- Adding generative UI components to Next.js or React applications with framework-specific hooks
Setup pitfalls
- Requires
Node.js22 or later; older versions will fail silently or with cryptic errors - Four secrets detected in the codebase—audit them before use in sensitive environments
- API keys for each provider (OpenAI, Anthropic, Google) must be set as environment variables; missing keys will fail at runtime
- Vercel AI Gateway requires proper authentication and quota setup; direct provider connections are simpler for prototyping
