Key Results
- StandingGemini 3.6 Flash ranks #61 of 87 models, and this is its best configuration. As a configuration, it is #119 of 151 configurations by Writing Elo (1010), in the bottom third of the board. Its 95% range (970 to 1059) overlaps 12 other configurations, ranked #110 to #122.
- MetricsBest-ranked: Length Adherence (82.8, 83rd of 151 configurations, -2.0 against the board median). Lowest-ranked: Tone & Voice Match (58.8, 125th of 151 configurations, -15.3 against the board median).
- ScriptsFrom 65.9 on Script 7 (personal technical walkthrough) to 74.0 on Script 8 (product release announcement): a 8.1-point spread across the 10 reference scripts.
- ConsistencyIts Writing Score moves ± 3.7 between drafts of the same script, against ± 2.5 for the median configuration: more variable than most.
- ValueGPT-6 Luna (medium) ranks far higher and costs about $0.0026 per script, against $0.052 per script for this one.
Louis's PickOf the two Gemini 3.6 Flash settings, this is the one I'd use. If you're not tied to Gemini 3.6 Flash, GLM-5.3 Flash (max) 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).
Tone & Voice Match ranks in the bottom half (125th of 151 configurations), so budget time for a voice pass.
The script format moves its score a lot. If most of your scripts look like its best or weakest format, that result is a better guide than the average.
Two drafts of the same script can differ noticeably, so generating a few drafts and keeping the best pays off.
Among proprietary models, Gemini 3.6 Flash is 45th of 53. As a configuration, it is 96th of 108 proprietary configurations. The best open-weight configuration, GLM-5.3 (max) at configuration #22, outranks it.

Skill Profile Across the Nine Metrics
Each corner is one metric on a 0 to 100 scale; the further out, the higher the score. A corner outside the dashed line beats the board median. Hover or tap a point for its exact score, and a metric name for what it rewards.
Scores by Metric
Nine metrics, each scored 0 to 100 and weighted into the Writing Score; the weight sits under each name. Rank is out of all 151 ranked configurations.
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: ± 13.0 between drafts against ± 6.6, so two drafts of the same script can score quite differently there.

Cost, Time and Tokens per Script
Logged on every run; none of these figures affects the Writing Score. Time is the average time to one accepted script, retries included. Cost is one script at the API list price.
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 69.3 combines their scores with the parts computed in code (Length Adherence and half of the Slop Score). The highest and lowest judge are 18.8 points apart on its Writing Score. That is wider than the board median of 13.4: GLM 5.3 Flash rates it noticeably higher than Claude Opus 5.5 (medium), so the Writing Score sits between two different opinions. 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.
Evaluation Setup
How this exact configuration was run and judged: route, model ID, dates, sampling and prompt.
- Accessed viaGoogle Gemini API · model page ↗.
- Exact model / route id
gemini-3.6-flash(the request sets no level; the provider applies medium thinking). - Generations5 independent runs × 10 scripts = 50 drafts, stored after generation and never edited.
- Run dates2026-10-11.
- JudgesClaude Opus 5.5 at medium effort through the Claude Code subscription, GPT-6.1 Sol at medium reasoning through the Codex CLI, GLM 5.3 Flash through OpenRouter, and Jev 1.13 from TypeSafe. One call per judge per draft. All four score every draft on their own, blind to which model wrote it. The three LLM judges use the identical rubric and have to quote evidence before they score a metric. Jev answers the same rubric as one question per metric, choosing among five described quality levels, and writes no text. Seven metrics are the plain average of the four judges. Length is computed from the spoken word count, and Slop is half computed (lexical scans minus the spoken-dash penalty) and half judged. The Writing Elo is cross-checked with a Bradley-Terry fit of the same pairwise results (methodology).
- Sampling and promptThe provider's default sampling, with no fine-tuning and no system-prompt changes. Every current-ranked model gets the same prompt, about 13,000 tokens (the count shifts a bit with each model's tokenizer): a style guide built from Louis's voice and storytelling guides, the target length, and the brief with its research packet. Generation is closed-book on every route: the prompt is the only source, with no web search, browsing, code execution, file access or other tool (generation).
- What stays privateThe exact rubric and any non-public reference material. Each script is normally benchmarked before its video is published, which lowers the odds that a model has seen the reference, though it does not rule it out (why).
