Dataset	onto4all
Description	Onto4All is a subsample of other open source performant conversational datasets. We start with a carefully curated subset of the OpenHermes-2.5-Viet dataset, co-created by @qnguyen3 and @Teknium. This dataset is specifically designed to support the training and evaluation of Multilingual language models, such as Vistral-7B-chat and VinaLlama-7B-chat, and is derived from our Supervised Fine-Tuning (SFT) data. We have included Vietnamese here, but will add more languages.
