            ➡️️ **Intended Use**: this demo is intended to showcase an early finetuning of [sotopia-pi-mistral-7b-BC_SR](https://huggingface.co/cmu-lti/sotopia-pi-mistral-7b-BC_SR)/

            ⚠️ **Limitations**: the model can and will produce factually incorrect information, hallucinating facts and actions. As it has not undergone any advanced tuning/alignment, it can produce problematic outputs, especially if prompted to do so. Finally, this demo is limited to a session length of about 1,000 words.

            🗄️ **Disclaimer**: User prompts and generated replies from the model may be collected by TII solely for the purpose of enhancing and refining our models. TII will not store any personally identifiable information associated with your inputs. By using this demo, users implicitly agree to these terms.
