Why am I seeing this Ranked on recency

It is here mostly because it is new. Freshness is the largest single contributor to its score, which means nothing about the story except that it is recent.

Nothing much is corroborating this yet. On a quiet day in hardware that is enough to reach the top of the section — recency, not significance, is doing the work here.

Link-outLink-out, because it scores 0.42, below the 0.50 bar for a write-up. Link-out means we point at the publisher and say nothing of our own.

Blended score 0.423 — every figure below is computed, none of it is editorial.

Corroboration 0.35 0.39 +0.135 32% 1 independent org on the story. Tier-3 aggregators never corroborate — they can show something is circulating, never that it is true.

Freshnessleads 0.20 0.85 +0.171 40% Halves every 10 hours from the newest item on the story. This is the only factor that rewards a story for nothing more than being recent.

Corroboration counts distinct organisations, once each, and only from tiers 1 and 2. Freshness halves every 10 hours, so this ranking is a snapshot and will differ at the next build.

What happened

Mixture-of-experts (MoE) inference on consumer hardware is bounded by weight memory: a 35B-class model is 19.5GB at 4-bit, and sparsity shrinks the compute per token, not the bytes that must be held. Naive offloading to SSD does not help on its own, because layer N+1's experts must be chosen before layer N's output exists, so the reads cannot start early enough to hide behind compute. We present Edge0, a streaming MoE inference engine that closes the gap with a prerouter: a per-layer head predicts the next layer's routing one token ahead, and the prediction is consumed as the routing itself, so the staged expert set equals the routed set and nothing is dropped.
