# Pygmalion 2.7B |
|
|
|
## Model description |
|
|
|
Pymalion 2.7B is a proof-of-concept dialogue model based on EleutherAI's [gpt-neo-2.7B](https://huggingface.co/EleutherAI/gpt-neo-2.7B). |
|
|
|
**Warning:** This model is **NOT** suitable for use by minors. It **will** output X-rated content under certain circumstances. |
|
|
|
## Training data |
|
|
|
The fine-tuning dataset consisted of 56MB of dialogue data gathered from multiple sources, which includes both real _and_ partially machine-generated conversations. |
|
|
|
## Training procedure |
|
|
|
Model weights were initialized from the `uft-2.7b` ConvoGPT model made available in [this commit](https://huggingface.co/hakurei/convogpt/tree/07707377dee0aa7d1ee5363ef660b13eb5b73f9d/2.7b-uft). |
|
|
|
The model was then further fine-tuned on ~48.5 million tokens for ~5k steps on 4 NVIDIA A40s using DeepSpeed. |
|
|
|
## Intended use |
|
|
|
### The easy way |
|
|
|
We provide a notebook with a Gradio UI for playing around with the model without having to manually format inputs. This notebook can be found [here](https://github.com/PygmalionAI/gradio-ui/blob/master/notebooks/GPU.ipynb). |
|
|
|
### The manual way |
|
|
|
The model can be used as a regular text generation model, but it'll perform best if the input prompt adheres to the following format: |
|
|
|
``` |
|
[CHARACTER]'s Persona: [A few sentences about the character you want the model to play] |
|
<START> |
|
[DIALOGUE HISTORY] |
|
You: [Your input message here] |
|
[CHARACTER]: |
|
``` |
|
|
|
Where `[CHARACTER]` is, as you can probably guess, the name of the character you want the model to portray, `<START>` should be used verbatim as a delimiter token to separate persona and scenario data from the dialogue, and `[DIALOGUE HISTORY]` is chat history so the model can have some conversational context to draw from. Ideally it'll be pairs of messages like: |
|
|
|
``` |
|
[CHARACTER]: [some dialogue here] |
|
You: [your response to the dialogue above] |
|
``` |
|
|
|
Apart from chat history, you can also just add example conversations in `[DIALOGUE HISTORY]` to show how the character should speak - ideally at the beginning, so it doesn't get confused as to what's conversation history vs. character definition. |
|
|
|
## Known issues |
|
|
|
We haven't played around with the model enough to enumerate them. Feel free to give us some feedback! |
