Prompt Response Writing SFT

Freelancer Overview

As an AI trainer, I have experienced a wide range of LLM evaluations with some of the leading AI training companies in US. The projects I have worked on have been diverse, ranging from comparing the output of simple SxS models to creating prompts using images and videos to comparing the accuracy of each model's response in multiple turns, and checking model responses to prompts on topics containing sensitive content. Recently, I experienced tutoring a special chatbot in avatar conversation mode to teach it how to create natural sounding Japanese conversation, which was enjoyable and interesting to see the new development of AI chatbot. I believe my knowledge and experiences of AI training can be directly utilized for your projects.
