Private AI Needs Verifiable Routing
bgmshana · x · 2026-07-19
This discusses an often-overlooked issue in 'private AI': TLS only proves you connected to a domain, not which GPU, model image, or runtime processed your prompt. It mentions the path from dstack to Chutes: the gateway checks the target TEE's measurement before forwarding, then encrypts and sends the prompt to that measured environment. The core idea is to turn 'plaintext only appears in approved environments' into an enforceable routing policy. The author also notes limitations: remote attestation doesn't prove model 'honesty' or eliminate side channels; if the client verifies a wrong or expired measurement, security fails. Chutes docs are strict: confidentialcompute is just metadata; real cryptographic guarantee relies on DCAP verification.
