New experimental daily game for aitrainer.work:
Every day, each day two AI models answer the same prompt, one voiced by Calca and one by Brina. Players place the pair on a scale, add tags if something felt off, and then see how the community split. Part data annotation task part research, hopefully it will keep visitors that are looking to enter the AI training space both entertained and educated while providing some curious insights.
