Warning LLM Code there are probably better options
This node pack partially integrates the [Nari Labs Dia](https://github.com/nari-labs/dia) text-to-speech model into ComfyUI using a single node for loading (onto GPU) and generation.
This is only text input, no audio input.
Dia allows generating dialogue with speaker tags (`[S1]`, `[S2]`) and non-verbal sounds (`(laughs)`, etc.). This node loads the model from Hugging Face Hub and generates audio directly using float32 precision. It requires a CUDA-enabled GPU.

## Usage Example
1. Add the `Dia TTS Generate` node from the `audio/DiaTest` category.
2. Configure the `repo_id` if needed.
3. Enter your dialogue script into the `text` input.
4. Adjust generation parameters (`cfg_scale`, `temperature`, `speed_factor`, etc.) as needed.
5. Connect the `audio` output to a `SaveAudio` or `PreviewAudio` node.
6. Queue the prompt.

## Notes
* This node **requires a CUDA-enabled GPU**. It will fail to load if CUDA is not detected.
* The first time you run the node for a specific `repo_id`, it will download the model files from Hugging Face Hub, which may take some time. Subsequent runs will use the cached model.
* Changing the `repo_id` will trigger a model reload.
* The first time you run the node it will download the model files from Hugging Face Hub, which may take some time. Subsequent runs will use the cached model.
* The model uses float32 precision internally.
* The Descript Audio Codec (DAC) dependency (`descript-audio-codec`) must be installed via `requirements.txt`.
