Cerebras Big Chip Club: Ajay Joshi on Zero-Trust AI & Private Compute

What if you could use AI without ever exposing your data? In this conversation, we sit down with Prof. Ajay Joshi — a 20-year computing systems veteran, professor at Boston University, and co-founder of Ciphersonic Labs — to talk about fully homomorphic encryption (FHE) and why it could become the default mode of operation for AI security. FHE allows computations to be performed on encrypted data without decrypting it. The math has been around since the 1980s, but it came with a 100,000x performance penalty that made it impractical. Ajay's team solved that — bringing the overhead down to less than 2x — and now they're commercializing the technology. +++ Subscribe to our channel! https://www.youtube.com/@Cerebras Cerebras builds the world’s largest AI chip — delivering up to 15× faster inference than leading GPUs.
