## 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:
```typescript
// 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.
