Google's private AI runs on sealed hardware, not on encrypted math News
Google's shipping private inference product runs Gemini inside hardware enclaves on custom chips, which is confidential computing rather than homomorphic encryption, and the company's actual homomorphic work is an unsupported research compiler.
Encrypted inference: can a model answer a question it cannot read? Lesson
The two competing ways to run AI on data the server is not supposed to see: sealed hardware enclaves, which ship today and are fast, and homomorphic encryption, which is mathematically stronger and still far too slow.

Google's compiler for fully homomorphic encryption: write a high-level program with annotations marking which values are secret, and it compiles down to backends including OpenFHE, Lattigo, tfhe-rs and Jaxite. Explicitly not an officially supported Google product.
