Cloudflare AI Gateway text generation examples
## Setup ```javascript import { createAiGateway } from 'ai-gateway-provider'; import { createOpenAI } from '@ai-sdk/openai'; const aigateway = createAiGateway({ accountId: 'your-cloudflare-account-id', gateway: 'your-gateway-name', apiKey: 'you••••••ey', }); const openai = createOpenAI({ apiKey: 'openai-api-key' }); ``` ## streamText example Use `streamText` to stream text responses: ```javascript import { streamText } from 'ai'; const result = await streamText({ model: aigateway([openai('gpt-4o-mini')]), prompt: 'Write a multi-part greeting.', }); let accumulatedText = ''; for await (const chunk of result.textStream) { accumulatedText += chunk; } console.log(accumulatedText); ``` ## generateText example Use `generateText` for non-streamed responses: ```javascript import { generateText } from 'ai'; const { text } = await generateText({ model: aigateway([openai('gpt-4o-mini')]), prompt: 'Write a greeting.', }); console.log(text); ```
