This is a demo of a **Russian**-speaking Mistral-based model. If you are interested in other languages, please check other models, such as [MPT-7B-Chat](https://huggingface.co/spaces/mosaicml/mpt-7b-chat). Это демонстрационная версия [квантованной Сайги/Мистраль с 7 миллиардами параметров](https://huggingface.co/IlyaGusev/saiga_mistral_7b_gguf), работающая на CPU. Сайга — это разговорная языковая модель, дообученная на корпусах, сгенерированных ChatGPT, таких как [ru_turbo_alpaca](https://huggingface.co/datasets/IlyaGusev/ru_turbo_alpaca), [ru_turbo_saiga](https://huggingface.co/datasets/IlyaGusev/ru_turbo_saiga) и [gpt_roleplay_realm](https://huggingface.co/datasets/IlyaGusev/gpt_roleplay_realm).
