Fourteen Cases, Three Defects: Letting the Workloads Tune the Scheduler
26 August 2026 · 7 min
We wrote the expected route for every kind of work the cluster does before sending a single request. The first run was 6 hits, 5 misses, 3 gaps. Every miss was a scheduler defect nobody had noticed for weeks — including …
The Cortex Grows Senses: ROCm for LLMs, Multimodal In and Out, and Four New Agents
11 July 2026 · 11 min · The Cortex Fleet #6
Six weeks since the flux2-dev ROCm debugging saga, the fix turned out to generalize far past image generation. A tour of what shipped: ROCm for LLM serving, the broker's first multimodal-input feature, four new agent rol…
Scheduling GPU Workloads at Home: A Capacity Model That Scales
31 May 2026 · 8 min
A rigorous capacity model for home GPU clusters — one that works on a single node today and extends naturally when new hardware arrives. Built around three state vectors, six diagnostic metrics, and the actual implementa…
Getting Wan2.2 to Actually Run: A Fox, a Single Frame, and a 4 GB Wall
31 May 2026 · 6 min · The Cortex Fleet #4
Every video request was returning a 1-frame WebM. Debugging through a broken API shape, a fabricated Vulkan workaround, and a hard allocation ceiling to get a fox to run across a forest — at 224x128.
Fleet Audit: Retiring Four Models and Justifying the Rest
27 May 2026 · 9 min · The Cortex Fleet #3
After a probe run that broke half the cluster, I used the wreckage as an opportunity. A systematic audit of every model in the cortex fleet: what the capability data says, what's redundant, what earns its VRAM, and four …
