The AI SDK is an open-source toolkit for building AI applications with JavaScript and TypeScript. Its unified provider API allows developers to use any language model and enables powerful UI integrations into leading web frameworks such as Next.js and Svelte. The latest release, version 4.1, introduces several significant features, including image generation capabilities, non-blocking data streaming, improved tool calling, and enhanced error handling for structured outputs. With these new features, developers can build more sophisticated AI applications, such as chatbots with private local LLMs, search engines powered by AI, and cross-platform chat applications. The AI SDK also supports a wide range of providers, including Replicate, OpenAI, Google Vertex AI, Fireworks, Cohere, Together AI, DeepInfra, DeepSeek, and Cerebras.
