Confidential computing
Hardware that keeps data and model weights encrypted and isolated while they are being processed, not only at rest or in transit.
Confidential computing uses trusted execution environments in the CPU or accelerator so that even the cloud operator cannot read what is being computed. Google's TPU 8tx, paired with AMD EPYC hosts, brings this to TPU fine-tuning and inference; Nvidia offers it on its H100 and later GPUs. It matters for regulated data and for protecting proprietary weights on shared infrastructure.
