The AI model evaluation platform Yupp.ai's CEO Pankaj Gupta posted on the X platform stating that the platform will soon cease operations, and access will be maintained for the next 15 days, during which users can download their data. Existing users will not be able to create new conversations starting today, and new users will also be unable to register.Yupp.ai launched in June 2025 and raised $33 million in seed funding last June, led by a16z. The platform allows users to compare various AI models for free; users can input prompts and view responses generated by multiple AIs in parallel. After selecting the best result, a "preference data package" is formed, which is used for the post-training and evaluation of AI models. The platform combines blockchain technology to achieve transparency in the evaluation process, allowing users to provide feedback in exchange for corresponding rewards, while AI developers obtain verifiable training data.

ChainCatcher news, according to the official announcement, the AI blockchain platform Yupp has completed a $33 million seed round financing, led by a16z founder Chris Dixon and a16z investment partner Elizabeth Harkavy. The Yupp platform allows users to compare various AI models for free; users can input prompts and view responses generated by multiple AIs side by side, and after selecting the best result, a "preference data packet" is formed. This data is used for the post-training and evaluation of AI models.The platform combines blockchain technology to achieve transparency in the evaluation process. Users can provide feedback and receive corresponding rewards, while AI developers obtain verifiable training data. The platform design turns human judgment into a cyclical resource: an increase in users brings more evaluation data, which improves model quality, and high-quality models attract more user participation.
