# Open-Assistant StableLM-7B SFT-7 Model


This is the 7th iteration English supervised-fine-tuning (SFT) model of 
the [Open-Assistant](https://github.com/LAION-AI/Open-Assistant) project. 
It is based on a StableLM 7B that was fine-tuned on human demonstrations 
of assistant conversations collected through the 
[https://open-assistant.io/](https://open-assistant.io/) human feedback web 
app before April 12, 2023. 

## Model Details

- **Developed by:** [Open-Assistant Contributors](https://open-assistant.io/)
- **Model type:** Transformer-based Language Model
- **Language:** English
- **Finetuned from:** [stabilityai/stablelm-base-alpha-7b](https://huggingface.co/stabilityai/stablelm-base-alpha-7b)
- **Code:** [Open-Assistant/model/model_training](https://github.com/LAION-AI/Open-Assistant/tree/main/model/model_training)
- **Demo:** TODO
- **License:** Creative Commons license ([CC BY-SA-4.0](https://creativecommons.org/licenses/by-sa/4.0/))

## Prompting

Two special tokens are used to mark the beginning of user and assistant turns:
`<|prompter|>` and `<|assistant|>`. Each turn ends with a `<|endoftext|>` token.

Input prompt example:
```
<|prompter|>What is a meme, and what's the history behind this word?<|endoftext|><|assistant|>
```
The input ends with the `<|assistant|>` token to signal that the model should 
start generating the assistant reply.
