                    - This Space runs on CPU only, and uses GGML with GPU support via Runpod Serverless.

                    - Some responses WILL take AT LEAST 20 seconds to respond   
                    - The Chatbot Arena (for now), is single turn only. Responses will be cleared after submission. 
                    - Responses from the Arena will be used for building reward models. These reward models can be bucketed by Personas.
