mlabonne / Jambatypus-v0.1

Jambatypus-v0.1

This model is a QLoRA fine-tuned version of ai21labs/Jamba-v0.1 on the chargoddard/Open-Platypus-Chat dataset.

It has been trained on 2xA100 80 GB using my LazyAxolotl - Jamba notebook.

This repo contains both the adapter and the merged model in FP16 precision.

I recommend using the ChatML template to use this model.
