Vercel AI SDK vs the provider SDK directly vs LangChain for a TypeScript app
pick Anthropic TypeScript SDK 7.0.93
Use the provider SDK directly when you call one model: @anthropic-ai/sdk 0.124.0 is a thin client over the API, so every feature lands the day it ships and nothing is translated. Reach for the AI SDK 7.0.93 when you need one interface across providers, streaming into React, or structured output with a schema. Both are reasonable; the AI SDK costs you an abstraction that lags each provider's newest options.

LangChain 1.5.10 brings retrieval, agents, and tool orchestration already assembled, at the cost of a large surface you inherit.
Wins when you want prebuilt retrieval and agent graphs and accept the dependency and API churn.
