Vercel AI SDK from Vercel standardizes streaming, tool calling, and provider switching in React apps. It is aimed at Next.js developers building chat apps, with a free open-source SDK; costs come from hosting and model APIs. Opinionated toward Vercel and React stacks, less ideal for mobile-native. Editorial teams should verify fit against their compliance and workflow needs before rolling it out broadly.
