Key Results

Louis's PickOf the three Muse Wonder settings, this is the one I'd use. If you're not tied to Muse Wonder, Claude Opus 5.5 (low) ranks clearly higher for no more per script.

More Context Behind These Results

Writing Elo comes from comparing its average on each script with every other configuration's average on that same script; a gap smaller than the draft-to-draft variation counts as a draw (what the ranges can and cannot show).

On Substance, Accuracy & Value, its best-ranked metric, the judges found its explanations deeper and more accurate than the typical configuration's. Length Adherence ranks in the bottom half (67th of 132 configurations), so plan on trimming or padding to reach the target length.

The script format moves its score. If most of your scripts look like its best or weakest format, that result is a better guide than the average.

Its drafts vary little, so the first draft is usually close to the next one.

It outranks 3 configurations that cost at least 50% more.

It ranks highest of the 7 Meta configurations on the board.

Among proprietary models, Muse Wonder is 12th of 47. As a configuration, it is 27th of 91 proprietary configurations. The best open-weight configuration, GLM-5.3 (max) at configuration #15, outranks it.

Scores by Reference Script

Every ranked configuration writes five drafts for each of the same 10 briefs, and each score is the mean of those drafts. The rank and board median compare it with every configuration on that script, which separates a weak result from a hard script. The result on the format closest to your own work is the most relevant.

Consistency Between Drafts

Every score on this page is the mean of 5 drafts per script. The ± is the standard deviation between those drafts: the larger it is, the more two drafts of the same script can differ.

Compared with the typical model, it varies most on Length Adherence: ± 13.9 between drafts against ± 7.1, so two drafts of the same script can score quite differently there. On the same comparison, it's steadiest on Substance, Accuracy & Value: ± 1.3 between drafts against ± 2.3.

Scores by Judge

Four judges score the same 50 stored drafts blind against the same rubric: three LLM judges from three labs, plus Jev, a typed judge from TypeSafe that rates each metric on five described quality levels. No single judge's taste decides the result. The Writing Score of 80.6 combines their scores with the parts computed in code (Length Adherence and half of the Slop Score). The highest and lowest judge are 10.6 points apart on its Writing Score. That is close to the board median of 13.8. Each judge also has its own scale, so every card shows that judge's score against its average across the board. How the panel works.
