According to Foresight News, ORA, formerly known as Hyper Oracle, has released an on-chain Optimistic privacy AI solution called 'opp/ai'. The solution combines Zero Knowledge Machine Learning (zkML) and Optimistic Machine Learning (opML), offering both privacy and performance. During testing, opp/ai demonstrated a 2-5 times performance improvement over zkML while maintaining its privacy and decentralization features.

Furthermore, opp/ai has the capability to integrate any zkML solution, meaning that improvements and optimizations in zkML will directly impact opp/ai. This development showcases the potential for enhanced privacy and performance in the field of AI and machine learning.
