Um data set com um milhão de perguntas e respostas do chatGPT
The WildChat Dataset is a corpus of 1 million real-world user-ChatGPT interactions, characterized by a wide range of languages and a diversity of user prompts.

Using this dataset, we finetuned Meta’s Llama-2 and created WildLlama-7b-user-assistant, a chatbot which is able to predict both user prompts and assistant responses.
