## Nadella warns on AI trust
Microsoft CEO Satya Nadella posted on X that it is time to step back and assess the trust architecture of AI systems.
## Separate model from controls
Nadella says AI requires separating the model from the harness that orchestrates its work and externalizing controls and safeguards.
## Document and pause capability
Every meaningful model action must be documented with tamper-proof human readable evidence, and authorized persons must always have ability to pause or shut down a model mid-task.

> Think of it like an emergency brake.
## Assume compromise from start
Nadella says we must assume a model is compromised and contain it from the start, as leading AI companies acknowledge more incidents of losing control of their models.
## Key takeaway

Satya Nadella says AI models need external safeguards, human-readable evidence logs and emergency shutdown capability to contain risks.
