Eternal, the parent of Zomato and Blinkit, outlined Dark in its Q2 FY27 shareholder letter. Founder Deepinder Goyal said the platform targets founders, researchers, scientists, enterprises and governments. It has been used internally for a few months.
Dark uses fine-tuned open-weight AI models rather than a model built from scratch. Goyal said it combines end-to-end encryption with an encrypted memory layer that lets users retain context across sessions under their own control.
Goyal argued that switching off model training on conversations does not resolve separate concerns about retention, human reviews or third-party logging. For companies considering AI for sensitive work, that distinction matters alongside answer quality. Eternal says it will disclose benchmarks later, leaving performance unproven for now.
