Vercel AI SDK

Vercel AI SDK is an open-source TypeScript framework that abstracts the complexity of working with multiple AI model providers. Whether you're building chatbots, agents, or text-generation features, the SDK provides a single API that works across OpenAI, Anthropic, Google, Mistral, Meta, and other platforms.

Highlights

• Unified API across 100+ models and 16+ providers with zero vendor lock-in
• Real-time response streaming built-in, no custom parsing needed
• Production-ready reliability through automatic fallbacks and error handling
• Multi-modal support: text, images, video, speech, and transcription
• Tool calling and structured outputs for building intelligent agents
• Framework agnostic: works with React, Next.js, Node.js, and other environments

The SDK is free and open source, maintained by a large community. It's ideal for developers experimenting with multiple AI providers or avoiding dependence on a single platform.
