The TextGenerate node uses a CLIP model to create text based on a user's prompt. It can optionally use images, video, or audio as additional context to guide the text generation. You can control the length of the output, enable a thinking mode for supported models, and choose whether to use random sampling with various settings or to generate text without sampling. ## Inputs ### Common Inputs | Parameter | Description | Data Type | Required | Range | | ---------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------------- | -------- | ------------------- | | `sampling_mode` | Controls whether random sampling is used during text generation. When set to "on", additional sampling parameters become available. When set to "off", the node generates text without random sampling. | DYNAMIC\_COMBO | Yes | `"on"`
`"off"` | | `clip` | The CLIP model used for tokenizing the prompt and generating text. | CLIP | Yes | N/A | | `prompt` | The text prompt that guides the generation. This field supports multiple lines and dynamic prompts. The default value is an empty string. | STRING | Yes | N/A | | `image` | An optional image that can be used alongside the text prompt to influence the generated text. | IMAGE | No | N/A | | `video` | Video frames as an image batch. Assumed to be 24 FPS; subsampled to 1 FPS internally. | IMAGE | No | N/A | | `audio` | An optional audio input that can be used alongside the text prompt to influence the generated text. | AUDIO | No | N/A | | `max_length` | The maximum number of tokens the model will generate. The default value is 512. | INT | Yes | 1 to 32768 | | `thinking` | Operate in thinking mode if the model supports it. The default value is False. | BOOLEAN | No | True or False | | `use_default_template` | Use the built in system prompt/template if the model has one. The default value is True. This is an advanced parameter. | BOOLEAN | No | True or False | ### Sampling Parameters (when `sampling_mode` is "on") | Parameter | Description | Data Type | Required | Range | | -------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------ | --------- | -------- | ------------------------- | | `temperature` | Controls the randomness of the output. Lower values make the output more predictable, higher values make it more creative. The default value is 0.7. | FLOAT | Yes | 0.01 to 2.0 | | `top_k` | Limits the sampling pool to the top K most likely next tokens. A value of 0 disables this filter. The default value is 64. | INT | Yes | 0 to 1000 | | `top_p` | Uses nucleus sampling, limiting choices to tokens whose cumulative probability is less than this value. The default value is 0.95. | FLOAT | Yes | 0.0 to 1.0 | | `min_p` | Sets a minimum probability threshold for tokens to be considered. The default value is 0.05. | FLOAT | Yes | 0.0 to 1.0 | | `repetition_penalty` | Penalizes tokens that have already been generated to reduce repetition. A value of 1.0 applies no penalty. The default value is 1.05. | FLOAT | Yes | 0.0 to 5.0 | | `seed` | A number used to initialize the random number generator for reproducible results. The default value is 0. | INT | Yes | 0 to 18446744073709551615 | | `presence_penalty` | Penalizes new tokens based on whether they have appeared in the text so far, encouraging the model to talk about new topics. The default value is 0.0. | FLOAT | No | 0.0 to 5.0 | **Note:** The sampling parameters above are only active and visible in the node interface when `sampling_mode` is set to "on". When `sampling_mode` is set to "off", no sampling parameters are available and the node generates text without random sampling. ## Outputs | Output Name | Description | Data Type | | ---------------- | ---------------------------------------------------------------------------------------------- | --------- | | `generated_text` | The text generated by the model based on the input prompt and optional image, video, or audio. | STRING | > This documentation was AI-generated.
