# Usa Gen 4 Turbo con Comfy Router

> Llama a runway/gen4_turbo con Comfy Router: endpoint, forma de la solicitud y respuesta que devuelve Router.

Referencia de API para `runway/gen4_turbo`, servida por Comfy Router desde Runway.

**Entrada:** Imagen, Texto · **Salida:** Video

## Inicio rápido

Crea una clave en [tu espacio de trabajo de Comfy](https://platform.comfy.org/profile/api-keys?onboarding=router) y expórtala como `COMFY_API_KEY`. Los fragmentos de Python y TypeScript usan los SDK de Comfy (`pip install comfy-sdk` y `npm install @comfyorg/sdk`); el fragmento de cURL es la misma llamada por HTTP sin procesar.

**ID del modelo:** `runway/gen4_turbo`

**Endpoint:** `POST https://api.comfy.org/v2/models/runway/gen4_turbo`

**Esperar el resultado**

```python Python theme={null}

**Encolar y recoger más tarde**

El mismo cuerpo, enviado a `POST https://api.comfy.org/v2/models/runway/gen4_turbo/requests`. Router responde `201` con un `request_id` en cuanto se admite la ejecución, y el resultado se recoge cuando está listo, desde este proceso o desde otro. [Entrega en cola](https://docs.comfy.org/es/development/comfy-router/queue.md) explica el estado, la cancelación y la recogida.

## Esquema

### Entrada

**duration** `integer` *required*

Valores posibles: `2`, `3`, `4`, `5`, `6`, `7`, `8`, `9`, `10`

**model** `string`

Modelo que se usará para la generación. En la ruta del Comfy Router `POST /v2/models/runway/{model}`, este campo se suministra desde la ruta y NO DEBES enviarlo; en la ruta v1 `POST /proxy/runway/image_to_video` es requerido y está restringido a RunwayModelEnum (`gen4_turbo`).

**promptImage** `string | object[]` *required*

Imagen o imágenes que se usarán para la generación del video. Puede ser una sola URI o un arreglo de objetos de imagen con posiciones.

**promptText** `string`

Prompt de texto para la generación

**ratio** `string` *required*

Valores posibles: `1280:720`, `720:1280`, `1104:832`, `832:1104`, `960:960`, `1584:672`, `1280:768`, `768:1280`

**seed** `integer` *required*

Semilla aleatoria para la generación

Rango: `0` a `4294967295`

Formato: `int64`

Generado a partir del esquema que Router sirve en `GET /v2/models/runway/gen4_turbo/openapi.json`, el mismo documento con el que valida una llamada antes de que la solicitud llegue al proveedor.

### Salida

**createdAt** `string (date-time)` *required*

Fecha y hora de creación de la tarea

Formato: `date-time`

**id** `string` *required*

ID de la tarea

**output** `string[]`

Las URL de los recursos de la generación finalizada: para `runway/gen4_turbo` y `runway/aleph2`, cada elemento es una URL de VIDEO. Están presentes cuando la tarea termina con éxito; esta lista ES el resultado.

**progress** `number`

Valor flotante entre 0 y 1 que representa el progreso de la tarea. Solo está disponible si el estado es RUNNING.

Rango: `0` a `1`

Formato: `float`

**status** `string` *required*

Estados posibles de una tarea de Runway.

Valores posibles: `SUCCEEDED`, `RUNNING`, `FAILED`, `PENDING`, `CANCELLED`, `THROTTLED`

## Antes de lanzar

Los SDK crean una `Idempotency-Key` y la reutilizan para los reintentos automáticos. Para los reintentos manuales, reutiliza la clave original. Router puede mantener la conexión abierta hasta 10 minutos.

Cuando una solicitud falla, Router envía un encabezado de respuesta `X-Comfy-Error-Type` que explica el motivo. Un `422` significa que Router rechazó la entrada antes de llamar al proveedor, y un `413` significa que el cuerpo de la solicitud era más grande de lo que Router acepta. Descarga los recursos generados de inmediato, porque [las URL de resultados pueden caducar](https://docs.comfy.org/es/development/comfy-router/reference.md#recursos-del-resultado).

Cualquier límite de tamaño mencionado en la descripción de un campo más arriba es el límite propio del proveedor para ese campo, citado de la especificación del proveedor. Router aplica un tope aparte al cuerpo completo de la solicitud, con el que cuentan los medios codificados en base64: consulta [tamaño del cuerpo de la solicitud](https://docs.comfy.org/es/development/comfy-router/limitations.md#los-cuerpos-de-las-solicitudes-tienen-un-límite).

Esta página documenta un modelo socio al que se llama a través de Comfy Router. El mismo paquete `comfy-sdk` / `@comfyorg/sdk` también incluye un segundo cliente, para ejecutar todo un gráfico de flujo de trabajo de ComfyUI en Comfy Cloud: `Comfy(api_key=...)` / `new Comfy({ apiKey })`, con `client.workflows`, `client.assets` y `client.jobs`. Consulta [SDK de Comfy](https://docs.comfy.org/es/development/api-development/sdks.md).
