Master Vercel AI SDK v6: generateText(), streamText(), structured output with generateObject() and Zod schemas, RAG with Embeddings, image generation, and multimodal input for production AI apps.
Vercel AI SDK v6 is a comprehensive toolkit for building AI applications, unifying the interfaces of multiple AI providers so developers can support OpenAI, Anthropic, Google, and other major models with a single codebase.
generateText() and streamText() are the two most core functions. The former is suited for scenarios where you need a complete response before processing; the latter is ideal for real-time streaming output. Both support tool calling and structured output.
Structured output (generateObject()) is a major highlight of v6. Combined with Zod schemas, it lets AI return type-safe JSON, completely eliminating the need for manual parsing of AI responses.
The Embedding functionality in AI SDK v6 makes implementing RAG (Retrieval-Augmented Generation) straightforward—vectorize and store documents, retrieve the most relevant context at query time, and effectively improve the accuracy of AI responses.
Image generation (generateImage) and multimodal input support are important new capabilities in v6. Combined with vision-capable models, you can build AI applications that analyze images and generate visual content.
