On June 13, according to the official announcement, Yupp completed a $33 million seed round of financing, led by a16z. The Yupp platform allows users to compare various AI models for free, input prompts and view responses generated by multiple AIs in parallel, and select the best results to form a "preference packet", which is used for post-training and evaluation of AI models.

The platform combines blockchain technology to achieve transparency in the evaluation process, where users can provide feedback to receive corresponding rewards, while AI developers obtain verifiable training data. The design of the platform makes human judgment a circular resource: an increase in users leads to more evaluation data, which improves the quality of the models, and high-quality models attract more user participation.
