    This is a more open source alternative to ChatGPT, and I don't find it as limited as ChatGPT's freemium limitations.

    It's a good option. Unlike ChatGPT Free, HuggingChat offers a range of models, the main one being llama. However, I have encountered problems with those models when asking questions in Spanish and Portuguese, where instead of giving a proper answer, it returned a sequence of random characters. So it is not too reliable if working with non English prompts.

    the models are bad and repetitive in answering the questions, the documents are a problem because the models don't answer right to a question related to a single document. the model gives me multiple document instead and make lots of mistakes
