Vercel AI is a TypeScript SDK that provides a unified API for interacting with large language models across many providers. It includes utilities for text, image, speech, and video generation as well as agent and tool‑calling workflows.

Use cases

• Generate text responses from LLMs in a web or Node.js app
• Build AI‑powered chat interfaces with streaming output
• Create agents that can call tools or retrieve data
• Integrate image, speech, or video generation into a JavaScript project
• Switch between OpenAI, Anthropic, Grok, and other providers with a single line of code

When to choose

• You are developing a JavaScript/TypeScript application and need a single library to work with many LLM providers.
• You want built‑in streaming, fallbacks, and multi‑model support without writing custom adapters.
• Your project uses React, Next.js, Svelte, Vue, or plain Node.js and you need framework‑agnostic hooks.
• You need to build agents or tool‑calling workflows with minimal boilerplate.

When to avoid

• Your stack is not JavaScript/TypeScript (e.g., Python, Rust, Go).
• You require low‑level model serving or custom GPU inference pipelines.
• You need a fully self‑hosted solution without any external provider dependencies.
