Requirements

Node.js v24+ is required to avoid compatibility issues with isolated-vm.

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)
}
