# 生成文本（AI SDK）

> 使用 Vercel AI SDK 和 Phaseo 非流式生成文本。

使用 `generateText` 和 `phaseo(modelId)` 执行单次生成。

```ts theme={null}
import { phaseo } from "@phaseo/ai-sdk-provider";
import { generateText } from "ai";

const result = await generateText({
  model: phaseo("openai/gpt-5-nano"),
  prompt: "Write a concise summary of Phaseo Gateway.",
});

console.log(result.text);
console.log(result.providerMetadata);
```

## 使用聊天历史

```ts theme={null}
import { phaseo } from "@phaseo/ai-sdk-provider";
import { generateText } from "ai";

const result = await generateText({
  model: phaseo("openai/gpt-5-nano"),
  messages: [
    { role: "system", content: "You are a terse assistant." },
    { role: "user", content: "Give me three bullet points on retrieval augmentation." },
  ],
});

console.log(result.text);
console.log(result.providerMetadata);
```

## 按模型设置

```ts theme={null}
import { phaseo } from "@phaseo/ai-sdk-provider";
import { generateText } from "ai";

const result = await generateText({
  model: phaseo("openai/gpt-5-nano", {
    temperature: 0.2,
    topP: 0.9,
    maxTokens: 300,
  }),
  prompt: "Draft a release note for an API update.",
});

console.log(result.text);
console.log(result.providerMetadata);
```

## Prompt 与 messages

* 单轮快速请求使用 `prompt`。
* 多轮上下文和角色控制使用 `messages`。
* 查询 `/v1/models` 以获取最新模型 ID（参见[模型发现](../get-models/index.mdx)）。
