Redpajama-3B SFT model

It is based on a RedPajama's 3B that was fine-tuned on human demonstrations of assistant conversations collected through the https://open-assistant.io/ human feedback web app before April 12, 2023.

supervised finetune on sequence of 5120 conversation dataset

Model Details

Developed by: Open-Assistant Contributors and iKala
Model type: Transformer-based Language Model
Language: English, Chinese, Japanese
Finetuned from: togethercomputer/RedPajama-INCITE-Base-3B-v1
Code: Open-Assistant/model/model_training

Prompting

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.
