$OPG OpenGradient (OPG) is solving the one problem every AI crypto project ignores: how do you actually prove an AI model ran correctly?

Using zero-knowledge machine learning (zkML) and Trusted Execution Environments (TEEs), OpenGradient provides cryptographic proof that a specific AI model was used and data was processed exactly as intended — making AI inference auditable on-chain for the first time at scale. The institutional backing speaks for itself: the project raised $9.5 million led by a16z Crypto with participation from Coinbase Ventures, SV Angel, and others — and the network already handles over 2 million inferences and 500,000 proofs across 2,000+ live models before most people have even heard of it.
