# LimaRP Persona-Scenario Generator (v5, Alpaca)
A previously unpublished LoRA adapter for [Yarn-Llama-2-7B-64k](https://huggingface.co/NousResearch/Yarn-Llama-2-7b-64k) made
for internal use. Its primary purpose is generating Persona and Scenario (summary) from LimaRP `yaml` source data.
To some extent it can work with different text types, however.
## Prompt format
```
### Input:
{Your text here}
### Response:
Charactername's Persona: {output goes here}
```
Replace `Charactername` with the name of the character you want to infer a Persona for.
By default this LoRA looks for the placeholder names `<FIRST>` and `<SECOND>` (in this
respective order) but it can work with proper names as well.
## Example
This image shows what would happen (red box) after adding data in the format shown in the left pane.
In practice the results would be double-checked and manually tweaked to diversify the
outputs and adding character quirks, peculiarities or traits that the model couldn't catch.
## Known issues
- While the scenario/summary is often remarkably accurate, personas don't show a very high accuracy and can be repetitive.
- Persona and Scenario may exhibit `gpt`-isms.
- Peculiar character quirks may not be observed by the model.
- The LoRA hasn't been extensively tested with different input formats.
- There are apparently issues with the EOS token getting generated too early. It's suggested to disable it.
