The TextGenerateLTX2Prompt node is a specialized version of a text generation node. It takes a user's text prompt and automatically formats it with specific system instructions before sending it to a language model for enhancement or completion. The node can operate in two modes: text-only or with an image reference, using different system prompts for each case.

## Inputs

| Parameter       | Data Type | Required | Range                                                         | Description                                                                                                                    |
| --------------- | --------- | -------- | ------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------ |
| `clip`          | CLIP      | Yes      |                                                               | The CLIP model used for text encoding.                                                                                         |
| `prompt`        | STRING    | Yes      |                                                               | The raw text input from the user that will be enhanced or completed.                                                           |
| `max_length`    | INT       | Yes      |                                                               | The maximum number of tokens the language model is allowed to generate.                                                        |
| `sampling_mode` | COMBO     | Yes      | `"greedy"`<br />`"top_k"`<br />`"top_p"`<br />`"temperature"` | The sampling strategy used to select the next token during text generation.                                                    |
| `image`         | IMAGE     | No       |                                                               | An optional input image. When provided, the node uses a different system prompt that includes a placeholder for image context. |

**Note:** The behavior of the node changes based on the presence of the `image` input. If an image is provided, the generated prompt will be formatted for an image-to-video task. If no image is provided, the formatting will be for a text-to-video task.

## Outputs

| Output Name | Data Type | Description                                                            |
| ----------- | --------- | ---------------------------------------------------------------------- |
| `output`    | STRING    | The enhanced or completed text string generated by the language model. |
