R98 · Squarified treemap of changing data
Every answer below carries the name of the model that wrote it. Blind refers to the scoring: the review was done without knowing which model produced which answer — the published result names them.
2 of the 8 local models delivered nothing through our test harness in this round — for reasons that lie with our setup, not with the models. Those cards are marked DNF like any other, but they are not evidence about those models — the reason is noted on the card itself.
Show task
Create ONE self-contained HTML file (STRICT LIMIT: max 7000 characters in total — this is a budget on characters, not on lines, so removing line breaks does not help) that draws a squarified treemap on a <canvas>: split a set of about 20 weighted items into nested rectangles that fill the whole area, choosing the split direction so the rectangles stay close to square rather than becoming thin slivers. Let the weights drift slowly over time and animate each rectangle towards its new position and size instead of jumping. Label the largest rectangles with their share. Smooth requestAnimationFrame animation, NO user input, starts immediately and keeps running (restart with a fresh random instance when finished). No external libraries, no comments needed. Output ONLY the HTML file content, nothing else.
The answers
Local models (Brain cluster) — identical prompt, shuffled order (the sequence is not a ranking)
gemma4:26bharness
No answer reached us (TIMEOUT) — and the reason lies with our setup, not with the model: reasoning consumed the entire token budget (3 min 28 s, zero characters of answer); larger budgets are refused by the gateway Counted as a did-not-finish, but it is not evidence about this model.
llama3.1:8bDNF
No usable answer reached the harness (TIMEOUT). Counted as a did-not-finish.
qwen3:8bharness
No answer reached us (ERR) — and the reason lies with our setup, not with the model: reasoning consumed the entire token budget and the answer stayed empty; the gateway rejects budgets above 3000 tokens Counted as a did-not-finish, but it is not evidence about this model.
