Brief
"Vercel AI SDK — Build AI Web Apps Fast" is a Build / Do reference from Vercel. Vercel's free AI SDK connects Next.js or React apps to any LLM (OpenAI, Gemini, Anthropic, Groq) in minutes. Handles streaming, tool calls, and multi-step agents. Indian developers use it with Krutrim too. It is listed for readers across the India AI ecosystem in a framework deployment context.
Builder choices in India still depend on cost, language support, and where data can live. This page only restates the stored summary and points you to Vercel; it does not rank vendors or invent pricing.
What to do next: open the official Vercel page, check setup and constraints, then compare other Build items if you are still choosing a stack.
