Channels
The local endpoint records 64.2% of the available signal against 99.5% from the strongest paid channel, a gap of 35.3 points. Each tick is one task, full height a clean pass; the short and missing ticks are where a channel dropped out.

Core against hard
Harder tiers exist to separate channels the core tier cannot. On the hard tier qwen3.8-27b-local gives up 0.15 against core, 7 channels hold within 0.02, and the field spreads over 0.47 points — the number that says whether the tier ranks anyone.
rightmost column: change from core to hard, so a negative number is a channel losing ground on the hardest tier
By task type
Mean score per channel. Build and fix tasks execute hidden tests; diagnose and review are graded blind against written ground truth.

Where qwen3.8-27b-local loses
21 of 37 tasks scored below a clean pass, 7 of them at zero. A zero is rarely diffuse weakness: it is usually one small defect that costs the whole task.

What the score costs
Quality against spend for the whole run. gpt-5.6-luna reaches 93.1% for $0.036; the local channel is free but sits 35.3 points under the best paid channel.
horizontal: run cost, log scale · vertical: % of available points
What a point costs
Tokens spent per point scored, so a channel that talks four times as much for the same score shows it here. qwen3.8-27b-local spends 977 completion tokens per point; qwen3.8-max spends 16,342. Verbosity is length relative to the field median on the same task (1.0 = typical); answer share is the fraction of a reply that is the deliverable rather than prose.
