WeniGPT-QA-Mixtral-7B-5.0.1-KTO

Weni/WeniGPT-QA-Mixstral-7B-5.0.1-KTO

This model is a fine-tuned version of [mistralai/Mixtral-8x7B-Instruct-v0.1] on the dataset Weni/WeniGPT-QA-Binarized-1.2.0 with the KTO trainer. It is part of the WeniGPT project for Weni. Description: WeniGPT Experiment using KTO trainer with no collator, Mixstral model and no system prompt.

It achieves the following results on the evaluation set: {'eval_loss': 0.014605735428631306, 'eval_runtime': 1025.937, 'eval_samples_per_second': 0.476, 'eval_steps_per_second': 0.119, 'eval/rewards/chosen': 6.546164512634277, 'eval/rewards/rejected': -30.777591705322266, 'eval/kl': 0.25049710273742676, 'eval/logps/chosen': -129.4441375732422, 'eval/logps/rejected': -508.0271301269531, 'eval/rewards/margins': 37.32375621795654, 'epoch': 1.99}
