TanStack AI

A powerful, type-safe AI SDK for building AI-powered applications.

• Provider-agnostic adapters (OpenAI, Anthropic, Gemini, Ollama, etc.)
• Tree-shakeable adapters - Import only what you need for smaller bundles
• Multimodal content support - Send images, audio, video, and documents
• Image generation - Generate images with OpenAI DALL-E/GPT-Image and Gemini Imagen
• Chat completion, streaming, and agent loop strategies
• Headless chat state management with adapters (SSE, HTTP stream, custom)
• Isomorphic type-safe tools with server/client execution
• Enhanced integration with TanStack Start - Share implementations between AI tools and server functions

Tree-Shakeable Adapters

Import only the functionality you need for smaller bundle sizes:

// Only chat functionality - no summarization code bundled
import { openaiText } from '@tanstack/ai-openai/adapters'
import { generate } from '@tanstack/ai'

const textAdapter = openaiText()

const result = generate({
  adapter: textAdapter,
  model: 'gpt-4o',
  messages: [{ role: 'user', content: [{ type: 'text', content: 'Hello!' }] }],
})

for await (const chunk of result) {
  console.log(chunk)
}

Available adapters: openaiText, openaiEmbed, openaiSummarize, anthropicText, geminiText, ollamaText, and more.

Bonus: TanStack Start Integration

TanStack AI works with any framework (Next.js, Express, Remix, etc.).

With TanStack Start, you get a bonus: share implementations between AI tools and server functions with createServerFnTool:

import { createServerFnTool } from '@tanstack/ai-react'

// Define once, get AI tool AND server function (TanStack Start only)
const getProducts = createServerFnTool({
  name: 'getProducts',
  inputSchema: z.object({ query: z.string() }),
  execute: async ({ query }) => db.products.search(query),
})

// Use in AI chat
chat({ tools: [getProducts.server] })

// Call directly from components (no API endpoint needed!)
const products = await getProducts.serverFn({ query: 'laptop' })

No duplicate logic, full type safety, automatic validation. The serverFn feature requires TanStack Start. See docs for details.
