Vigogne-Stablelm-3B-4E1T-Chat

An attempt to fine-tune the stablelm-3b-4e1t model to explore the feasibility of adapting a "smaller-scale" language model, primarily pretrained on English datasets, for French chat.

License: A significant portion of the training data is distilled from GPT-3.5-Turbo and GPT-4, kindly use it cautiously to avoid any violations of OpenAI's terms of use.
