The AI toolkit for TypeScript

Website vercel.com
Overview

What it is

Vercel provides the developer tools and cloud infrastructure to build, scale, and secure a faster, more personalized web.

Intent

I need it when

Integrate multiple LLM providers with automatic failover and unified API

AI SDK works with Vercel's AI Gateway to switch between hundreds of AI models from one interface, manage API keys centrally, and implement automatic failover without code changes

Secure AI applications with enterprise-grade protection

Vercel platform provides Web Application Firewall, DDoS mitigation, Bot Management, and BotID protection; Pro/Enterprise plans include SAML SSO, audit logs, and compliance certifications (SOC 2, HIPAA, PCI DSS)

Build and deploy AI-powered applications quickly without managing infrastructure

AI SDK provides open-source TypeScript toolkit with streaming UI helpers, built-in adapters for OpenAI/Anthropic/xAI/Cohere, and zero-config deployment on Vercel's AI Cloud, enabling developers to ship AI features in minutes instead of days

Deploy AI agents and autonomous workflows at scale

AI SDK integrates with Vercel Agent, Workflow SDK, and Sandbox for secure code execution, enabling developers to build multi-step agentic workloads with durable state management and isolated execution environments

Stream long-running LLM responses to users with optimized performance

AI SDK includes streaming primitives and Vercel's globally distributed infrastructure ensures sub-300ms cache propagation and optimized edge delivery, reducing latency for real-time AI interactions

Drop

Not a fit when

  • User needs a non-TypeScript/JavaScript AI integration solution; AI SDK is TypeScript-first
  • User requires on-premise or self-hosted AI infrastructure; Vercel is cloud-only
  • User needs real-time model training or fine-tuning capabilities; AI SDK focuses on inference and integration
  • User operates in a restricted regulatory environment without Vercel Enterprise compliance (HIPAA, SOC 2 available only on Pro/Enterprise)
  • User requires direct control over underlying LLM infrastructure without provider abstraction
