`uploadFile()`
uploadFile()
파일을 프로바이더에 업로드하고, 이후 API 호출(예: generateText 또는 streamText 에 전달되는 메시지 콘텐츠 파트)에서 사용할 수 있는 ProviderReference 를 반환해요.
import { uploadFile } from 'ai';
import { openai } from '@ai-sdk/openai';
import fs from 'node:fs';
const { providerReference } = await uploadFile({
api: openai.files(),
data: fs.readFileSync('./photo.png'),
filename: 'photo.png',
});
