Mixtral-8x7B-ICDOPS-QA-2024

Model Card for Model stefan-m-lenz/Mixtral-8x7B-ICDOPS-QA-2024

This model is a PEFT adapter (e.g., LoRA) fine-tuned using the dataset ICDOPS-QA-2024 based on mistralai/Mixtral-8x7B-Instruct-v0.1. For more information about the training, see the dataset card.

Usage

Package prerequisites:

pip install transformers accelerate peft
