# Generar texto (AI SDK)

> Generación de texto sin streaming con Vercel AI SDK y Phaseo.

Usa `generateText` con `phaseo(modelId)` para generar una respuesta en una sola llamada.

```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);
```

## Con historial de chat

```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);
```

## Ajustes por modelo

```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 o mensajes

* Usa `prompt` para solicitudes rápidas de un solo turno.
* Usa `messages` para contexto de varios turnos y controlar los roles.
* Consulta `/v1/models` para mantener actualizados los ID de modelo (consulta [Descubrimiento de modelos](../get-models/index.mdx)).
