OpenAI | TanStack AI 文档

OpenAI 适配器提供对 OpenAI 模型的访问，包括 GPT-4o、GPT-5、图像生成（DALL-E）、文本转语音（TTS）和音频转录（Whisper）。

安装

npm install @tanstack/ai-openai

基本用法

typescript

import { chat } from "@tanstack/ai";
import { openaiText } from "@tanstack/ai-openai";

const stream = chat({
  adapter: openaiText("gpt-5.2"),
  messages: [{ role: "user", content: "Hello!" }],
});

基本用法 - 自定义 API 密钥

typescript

import { chat } from "@tanstack/ai";
import { createOpenaiChat } from "@tanstack/ai-openai";

const adapter = createOpenaiChat(process.env.OPENAI_API_KEY!, {
  // ... your config options
});

const stream = chat({
  adapter: adapter("gpt-5.2"),
  messages: [{ role: "user", content: "Hello!" }],
});

配置

typescript

import { createOpenaiChat, type OpenAIChatConfig } from "@tanstack/ai-openai";

const config: Omit<OpenAIChatConfig, 'apiKey'> = {
  organization: "org-...", // Optional
  baseURL: "https://api.openai.com/v1", // Optional, for custom endpoints
};

const adapter = createOpenaiChat(process.env.OPENAI_API_KEY!, config);

示例：聊天完成

typescript

import { chat, toServerSentEventsResponse } from "@tanstack/ai";
import { openaiText } from "@tanstack/ai-openai";

export async function POST(request: Request) {
  const { messages } = await request.json();

  const stream = chat({
    adapter: openaiText("gpt-5.2"),
    messages,
  });

  return toServerSentEventsResponse(stream);
}

示例：使用工具

typescript

import { chat, toolDefinition } from "@tanstack/ai";
import { openaiText } from "@tanstack/ai-openai";
import { z } from "zod";

const getWeatherDef = toolDefinition({
  name: "get_weather",
  description: "Get the current weather",
  inputSchema: z.object({
    location: z.string(),
  }),
});

const getWeather = getWeatherDef.server(async ({ location }) => {
  // Fetch weather data
  return { temperature: 72, conditions: "sunny" };
});

const stream = chat({
  adapter: openaiText("gpt-5.2"),
  messages,
  tools: [getWeather],
});

模型选项

OpenAI 支持各种特定于提供商的选项

typescript

const stream = chat({
  adapter: openaiText("gpt-5.2"),
  messages,
  modelOptions: {
    temperature: 0.7,
    max_tokens: 1000,
    top_p: 0.9,
    frequency_penalty: 0.5,
    presence_penalty: 0.5,
    stop: ["END"],
  },
});

推理

为支持推理的模型启用推理（例如，GPT-5、O3）。这允许模型展示其推理过程，该过程以思考中块流式传输

typescript

modelOptions: {
  reasoning: {
    effort: "medium", // "none" | "minimal" | "low" | "medium" | "high"
    summary: "detailed", // "auto" | "detailed" (optional)
  },
}

当启用推理时，模型的推理过程会与响应文本分开流式传输，并显示为 UI 中的可折叠思考部分。

摘要

总结长文本内容

typescript

import { summarize } from "@tanstack/ai";
import { openaiSummarize } from "@tanstack/ai-openai";

const result = await summarize({
  adapter: openaiSummarize("gpt-5-mini"),
  text: "Your long text to summarize...",
  maxLength: 100,
  style: "concise", // "concise" | "bullet-points" | "paragraph"
});

console.log(result.summary);

图像生成

使用 DALL-E 生成图像

typescript

import { generateImage } from "@tanstack/ai";
import { openaiImage } from "@tanstack/ai-openai";

const result = await generateImage({
  adapter: openaiImage("gpt-image-1"),
  prompt: "A futuristic cityscape at sunset",
  numberOfImages: 1,
  size: "1024x1024",
});

console.log(result.images);

图像模型选项

typescript

const result = await generateImage({
  adapter: openaiImage("gpt-image-1"),
  prompt: "...",
  modelOptions: {
    quality: "hd", // "standard" | "hd"
    style: "natural", // "natural" | "vivid"
  },
});

文本转语音

从文本生成语音

typescript

import { generateSpeech } from "@tanstack/ai";
import { openaiTTS } from "@tanstack/ai-openai";

const result = await generateSpeech({
  adapter: openaiTTS("tts-1"),
  text: "Hello, welcome to TanStack AI!",
  voice: "alloy",
  format: "mp3",
});

// result.audio contains base64-encoded audio
console.log(result.format); // "mp3"

TTS 声音

可用声音：alloy、echo、fable、onyx、nova、shimmer、ash、ballad、coral、sage、verse

TTS 模型选项

typescript

const result = await generateSpeech({
  adapter: openaiTTS("tts-1-hd"),
  text: "High quality speech",
  modelOptions: {
    speed: 1.0, // 0.25 to 4.0
  },
});

语音转文本

将音频转录为文本

typescript

import { generateTranscription } from "@tanstack/ai";
import { openaiTranscription } from "@tanstack/ai-openai";

const result = await generateTranscription({
  adapter: openaiTranscription("whisper-1"),
  audio: audioFile, // File object or base64 string
  language: "en",
});

console.log(result.text); // Transcribed text

转录模型选项

typescript

const result = await generateTranscription({
  adapter: openaiTranscription("whisper-1"),
  audio: audioFile,
  modelOptions: {
    response_format: "verbose_json", // Get timestamps
    temperature: 0,
    prompt: "Technical terms: API, SDK",
  },
});

// Access segments with timestamps
console.log(result.segments);
