OpenCost 1.121.0: Now You Can See What Your Self-Hosted AI Models Actually Cost Per Token

OpenCost's new inference cost tracking shows the real per-token cost of running models on Kubernetes — including the KV cache effect and why low utilization makes self-hosting more expensive than it looks.

Why Queue Depth Beats CPU as a Kubernetes Autoscaling Signal

KEDA's SQS-based autoscaling replaces CPU and memory metrics with queue backlog — the metric that actually reflects whether an event-driven workload is under load.

Admission Webhooks Have a Bypass Problem — Runtime Verification Fixes It

A new NRI plugin moves supply chain verification below the Kubernetes API server, closing the static-pod and kubelet-bypass gaps that admission webhooks like Kyverno and OPA Gatekeeper can't cover.

Your Personalization Problem Is an Architecture Problem, Not a Model Problem

Vespa's case for real-time personalization: most teams don't have a ranking-quality problem, they have a retrieval-then-rank pipeline that can't act on signals until it's too late.
