Week of August 17, 2026

This is the short public index for the week of August 17–23. The detailed posts remain the source of truth. This page is a rollup of already-published measurements and decisions. It does not add a new benchmark run.

What the week actually did. Dual-Spark DS4-F changed weights, not the 1M/6 recipe. oMLX ANE prefill was measured twice on the M3 Ultra and the chunking fix landed upstream. StackChan stopped being a lamp. Ornith stayed the M3 text candidate. A four-Spark desk rack exists as CAD, not steel. Hermes finally drew the token table it already had. Sunday, the H2C printed a Benchy.

Do not mix these rows into one ranking. Different hosts, engines, prompt lengths, and jobs.

Also this week, not a separate post

The Bambu H2C arrived early (original ETA August 25). Sunday it finished first calibration, AMS 2 Pro #1, and a built-in Benchy on Soleyin matte grey PLA. Hull, overhangs, bridges, and chimney were clean; leftover stringing is cosmetic. Next prints are a purge bin, then Gridfinity, then the Spark-rack retainers from the inference-box model.

The living NAS page was updated August 20: RAID-6 Healthy, local backup tier still not 3-2-1. Reachy Mini remains the original physical avatar; StackChan is the second body, not a second brain.

What we did not do. No new Terminal-Bench or SWE score. No four-Spark rack built. No claim that Tony's overnight 78→88 applies to this stack. No claim that GLM-5.3 was tested — those weights are not out.

How to read the week

The useful pattern is the same one as last month: pin recipes for fail-closed reasons, measure speed separately, and do not promote a patch because a tweet has a round number. StackChan earned a conversation post only after local control and a custom face were already proven. The usage plugin exists because the table was already there — the missing piece was a page.
