# ComfyCloudFlux2TextToImageNode - ComfyUI Built-in Node Documentation

> Runs the Flux 2 dev text-to-image model on a Comfy Cloud GPU and returns the generated image.

Runs the Flux 2 dev text-to-image model on a Comfy Cloud GPU and returns the generated image. The `turbo` option applies the Turbo LoRA with a short schedule for a much quicker run at the cost of a little fidelity; turning it off performs the full-length dev pass without the LoRA. This is a beta node set, billed by how long it runs in credits.

## Inputs

| Parameter | Description | Data Type | Required | Range |
| - | - | - | - | - |
| `prompt` | The text prompt describing the image to generate. Leading and trailing whitespace is removed before submission. | STRING | Yes | 1 to 4096 characters |
| `seed` | Random seed that controls the generated result for reproducibility (default: 42). | INT | Yes | 0 to 18446744073709551615 |
| `aspect_ratio` | Aspect ratio of the output image (default: "1:1"). | COMBO | Yes | "1:1"<br />"3:4"<br />"2:3"<br />"3:2"<br />"4:3"<br />"16:9"<br />"9:16"<br />"21:9" |
| `megapixels` | Total pixel budget. 1.0 is about 1024x1024 at a square ratio (default: 1.0). | FLOAT | Yes | 0.1 to 16.0 (step 0.1) |
| `turbo` | Run the Turbo LoRA on a short schedule, trading a little fidelity for a much quicker run. Off runs the full dev pass with no LoRA (default: True). | BOOLEAN | Yes | True / False |

## Outputs

| Output Name | Description | Data Type |
| - | - | - |
| `IMAGE` | The image generated from the text prompt, returned as a ComfyUI image tensor that can be passed to other nodes. | IMAGE |
