Reviewer scorecard
“First-party SDK with excellent TypeScript support. Tool use and streaming work flawlessly. The agent loop is well-designed.”
“useChat and useCompletion hooks make AI UIs trivial. Provider abstraction means switching models is a one-line change.”
“Using the official SDK reduces risk of breaking changes. The agent patterns are production-tested by Anthropic themselves.”
“Well-maintained, provider-agnostic, and genuinely useful. The streaming utilities alone save hours of boilerplate.”
“Anthropic's approach to safe, capable agents sets the standard. The SDK makes best practices the default path.”
“The AI SDK is becoming the standard abstraction for AI in web apps. Tool calling and structured output support are excellent.”
