FastChat is an AI-driven chatbot tool designed for engaging with expansive language models. Users can select from three available models: Vicuna, Alpaca, and LLaMA, with Vicuna being the most high-performing, as per the developers’ assessment.

It’s essential to note that FastChat is currently in a research preview phase and is intended exclusively for non-commercial purposes. The tool may generate content that could be considered offensive, as its safety measures are limited in scope. Therefore, it should never be utilized for any unlawful, harmful, violent, racist, or sexual activities.

Users must agree to the terms of use, which detail the tool’s constraints and data collection policies. Additionally, a flagging feature is available for users to report any inappropriate content to the developers.

For the most optimal experience, it is recommended to use FastChat on desktop computers, as mobile devices may compromise the quality of interactions. FastChat is constructed with Gradio and provides a GitHub code repository, granting developers the flexibility to tailor and integrate the tool as needed.

In summary, FastChat is an AI chatbot tool that empowers users to engage with open language models, primarily for research purposes.
