AWS and NVIDIA plan 2 million more GPUs as their AI stack expands beyond accelerators

The scale of the AWS–NVIDIA expansion is the headline, but the builder consequence is broader: AWS is co-engineering more of the NVIDIA stack, from CPUs and interconnects to models, vector indexing and physical-AI infrastructure, rather than merely adding another GPU instance family.

OpenSSH 10.6 turns on hybrid post-quantum signatures and disables compression to cut side-channel risk

The release is more than routine maintenance. OpenSSH is changing cryptographic defaults, sacrificing some compression effectiveness for side-channel safety, and warning that AI-assisted security reports are pushing it toward a faster release cadence.

Cognition’s Fusion uses a frontier lead and cheaper sidekick to cut coding-agent task cost

Fusion is interesting less as another routing feature than as a different agent-cost architecture: two persistent model contexts divide planning, review and execution instead of making one expensive model handle every token. The practical question for builders is shifting from token price to cost per completed task.
