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

ParameterDescriptionData TypeRequiredRange
clipThe CLIP model used for text encoding.CLIPYes
promptThe raw text input from the user that will be enhanced or completed.STRINGYes
max_lengthThe maximum number of tokens the language model is allowed to generate.INTYes
sampling_modeThe sampling strategy used to select the next token during text generation.COMBOYes"greedy"
"top_k"
"top_p"
"temperature"
imageAn optional input image. When provided, the node uses a different system prompt that includes a placeholder for image context.IMAGENo
thinkingWhen enabled, the model will output its reasoning process before the final answer.BOOLEANNo
use_default_templateWhen enabled, the node will use the default chat template for formatting.BOOLEANNo
videoAn optional video input that can be used as additional context for generation.VIDEONo
audioAn optional audio input that can be used as additional context for generation.AUDIONo
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 using a system prompt that describes how to expand the prompt based on the image’s content. If no image is provided, the formatting will be for a text-to-video task using a system prompt that expands the prompt into a detailed video generation description.
