This repo contains GPTQ model files for OpenAssistant's Llama2 13B Orca 8K 3319.
Multiple GPTQ parameter permutations are provided; see Provided Files below for details of the options provided, their parameters, and the software used to create them.
<|system|>{system_message}</s><|prompter|>{prompt}</s><|assistant|>
The creator of the source model has listed its license as other, and this quantization has therefore used that same license.
As this model is based on Llama 2, it is also subject to the Meta Llama 2 license terms, and the license files for that are additionally included. It should therefore be considered as being claimed to be licensed under both licenses. I contacted Hugging Face for clarification on dual licensing but they do not yet have an official position. Should this change, or should Meta provide any feedback on this situation, I will update this section accordingly.
In the meantime, any questions regarding licensing, and in particular how these two licenses might interact, should be directed to the original model repository: OpenAssistant's Llama2 13B Orca 8K 3319.
Multiple quantisation parameters are provided, to allow you to choose the best one for your hardware and requirements.
Each separate quant is in a different branch. See below for instructions on fetching from different branches.
All recent GPTQ files are made with AutoGPTQ, and all files in non-main branches are made with AutoGPTQ. Files in the main branch which were uploaded before August 2023 were made with GPTQ-for-LLaMa.

This model is a fine-tuning of Meta's Llama2 13B model with 8K context size on a long-conversation variant of the Dolphin dataset (orca-chat).
Note: At least Huggingface Transformers 4.31.0 is required to load this model!

This model was fine-tuned with a context size of 8192 tokens using linear scaling of RoPE embeddings. This feature was recently
added to Huggingface transformers. Before loading this model please make sure
HF transformers >=4.31.0 is installed (pip install transformers>=4.31.0).
For the initial response use (e.g. the llama2 default system prompt works well):
<|system|>system message</s><|prompter|>user prompt</s><|assistant|>
For multi-turn conversations use:
<|system|>system message</s><|prompter|>Q1</s><|assistant|>A1</s><|prompter|>Q2</s><|assistant|>
The model was trained with the following 15 system messages used to generate the training examples (see ORCA paper):
This model was trained on:
Dataset Composition:
Tain (sampled):
orca-chat: 188842 (100%)
fanfics: 47760 (100%)
red_pajama: 188262 (25%)
Valid:
orca-chat: 5000
fanfics: 1000
red_pajama: 1000
The dataset shahules786/orca-chat combines similar examples of the GPT-4 subset of ehartford/dolphin to form longer conversations to improve long-context training.
Additionally, RedPajama and FanFics were used for classic language modelling as an auxiliary task to improve the RoPE scaling for the 8k context size.
