The AI model evaluation platform Yupp will cease operations, having previously raised $33 million in seed funding led by a16z

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.
