Signal: AI agents turn on their makers, Nvidia and Amazon push on PyTorch

This period brought a clear tension: agents are becoming more capable and more autonomous, and the trust and security questions around them are getting harder to defer. Microsoft's warning about agents as insider threats, the OpenCode breach, and the scrutiny of the AI buildout's financing all point the same way. For teams building products, the work is shifting from demonstrating capability to governing access, spend and infrastructure dependencies. Hardware competition is also widening, with Amazon and Nvidia both courting developers at the PyTorch layer.
