morzecrew/FRED-T5-RefinedPersonaChat

This model is a fine-tuned version of ai-forever/FRED-T5-1.7B on the RefinedPersonaChat. Inspired by SiberiaSoft/SiberianPersonaFred blogpost but dataset was improved to prevent toxic speech.

Prompt tips:

You can provide personal information form bot identity, name, age and etc..
