This model has been fine-tuned for question-answering task. It is possible to use it as a chat, but it doesn't work well because the dataset did not contain conversations.

Training and evaluation data

Dataset: s3nh/alpaca-dolly-instruction-only-polish

Each row has been converted into conversation using this function:

system_message = """Jesteś przyjaznym chatbotem"""

def create_conversation(sample) -> dict:
    strip_characters = "\"'"
    return {
        "messages": [
            {"role": "system", "content": system_message},
            {"role": "user",
             "content": f"{sample['instruction'].strip(strip_characters)} "
                        f"{sample['input'].strip(strip_characters)}"},
            {"role": "assistant",
             "content": f"{sample['output'].strip(strip_characters)}"}
        ]
    }
