OCHI

OCHI is a Ukrainian non-profit system, first designed in 2022 and led by Oleksandr Dmitriev, an adviser to the Defence Ministry, that centralises live video feeds from more than 15,000 Ukrainian drone crews onto a single battlefield-overview map for commanders. The original purpose was simple: instead of each reconnaissance and strike crew watching its own screen in isolation, OCHI puts their feeds side by side so a commander can see what is happening across a sector at once.

What began as a situational-awareness tool turned into an archive. The team realised the returning video was a record worth keeping, and it has since accumulated roughly two million hours of combat footage — which Dmitriev frames as the equivalent of more than two centuries of continuous viewing — growing by five to six terabytes of new video on an average day. He describes that body of data as raw material for battlefield AI: a training set that could teach systems to recognise targets, read tactics and judge how well particular weapons perform. “This is food for the AI,” he has said; “if you want to teach an AI, you give it two million hours of video, it will become something supernatural.”

The footage figure is a snapshot from late 2024, and the operators have not publicly named which AI developers, if any, draw on the archive. The system sits in the same situational-awareness space as Ukraine’s Delta system — which aggregates drone feeds through its own sub-systems — and intelligence-platform developers such as Griselda ; OCHI is reported as a standalone effort rather than a component of Delta.
