## Model Details |
|
|
|
The long-awaited release of our new models based on Llama-2 is finally here. Pygmalion-2 7B (formerly known as Metharme) is based on |
|
[Llama-2 7B](https://huggingface.co/meta-llama/llama-2-7b-hf) released by Meta AI. |
|
|
|
The Metharme models were an experiment to try and get a model that is usable for conversation, roleplaying and storywriting, |
|
but which can be guided using natural language like other instruct models. After much deliberation, we reached the conclusion |
|
that the Metharme prompting format is superior (and easier to use) compared to the classic Pygmalion. |
|
|
|
This model was trained by doing supervised fine-tuning over a mixture of regular instruction data alongside roleplay, fictional stories |
|
and conversations with synthetically generated instructions attached. |
|
|
|
This model is freely available for both commercial and non-commercial use, as per the Llama-2 license. |
|
|
|
|
|
## Prompting |
|
|
|
The model has been trained on prompts using three different roles, which are denoted by the following tokens: `<|system|>`, `<|user|>` and `<|model|>`. |
|
|
|
The `<|system|>` prompt can be used to inject out-of-channel information behind the scenes, while the `<|user|>` prompt should be used to indicate user input. |
|
The `<|model|>` token should then be used to indicate that the model should generate a response. These tokens can happen multiple times and be chained up to |
|
form a conversation history. |
|
|
|
### Prompting example |
|
|
|
The system prompt has been designed to allow the model to "enter" various modes and dictate the reply length. Here's an example: |
|
|
|
``` |
|
<|system|>Enter RP mode. Pretend to be {{char}} whose persona follows: |
|
{{persona}} |
|
|
|
You shall reply to the user while staying in character, and generate long responses. |
|
``` |
|
|
|
## Dataset |
|
The dataset used to fine-tune this model includes our own [PIPPA](https://huggingface.co/datasets/PygmalionAI/PIPPA), along with several other instruction |
|
datasets, and datasets acquired from various RP forums. |
|
|
|
## Limitations and biases |
|
|
|
The intended use-case for this model is fictional writing for entertainment purposes. Any other sort of usage is out of scope. |
|
|
|
As such, it was **not** fine-tuned to be safe and harmless: the base model _and_ this fine-tune have been trained on data known to contain profanity and texts that |
|
are lewd or otherwise offensive. It may produce socially unacceptable or undesirable text, even if the prompt itself does not include anything explicitly offensive. |
|
Outputs might often be factually wrong or misleading. |
