Key Results
StandingDeepSeek V4 Pro ranks #51 of 87 models through its best configuration, DeepSeek V4 Pro (high). This setting is #106 of 151 configurations by Writing Elo (1266), in the bottom third of the board. Its 95% range (1213 to 1320) overlaps 6 other configurations, ranked #100 to #107.
MetricsBest-ranked: Length Adherence (83.4, 81st of 151 configurations, -1.3 against the board median). Lowest-ranked: Slop Score (72.3, 127th of 151 configurations, -9.0 against the board median).
ScriptsFrom 68.4 on Script 10 (engineering process walkthrough) to 76.6 on Script 6 (founder announcement): a 8.2-point spread across the 10 reference scripts.
ConsistencyIts Writing Score moves ± 3.3 between drafts of the same script, against ± 2.5 for the median configuration: typical.
ValueGPT-6 Luna (medium) ranks far higher and costs about $0.0026 per script, against $0.070 per script for this one.
Louis's PickI'd use DeepSeek V4 Pro (high) instead: same model, a higher rank with an overlapping Elo range for less 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).
Slop Score ranks in the bottom half (127th of 151 configurations), so expect filler phrases and AI tells to clean out.
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.
It outranks 5 configurations that cost at least 50% more.
Among open-weight models, DeepSeek V4 Pro is 15th of 34. This setting is 22nd of 43 open-weight configurations. The best open-weight configuration is GLM-5.3 (max), at configuration #22, and every configuration above it is proprietary.

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 Slop Score: ± 4.0 between drafts against ± 1.6, so two drafts of the same script can score quite differently there.

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 73.1 combines their scores with the parts computed in code (Length Adherence and half of the Slop Score). The highest and lowest judge are 16.2 points apart on its Writing Score. That is close to the board median of 13.4. 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.
Exact model / route iddeepseek/deepseek-v4-pro at reasoning level: xhigh.
Generations5 independent runs × 10 scripts = 50 drafts, stored after generation and never edited.
Run dates2026-10-08.
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).
Frequently Asked Questions
How Good Is DeepSeek V4 Pro (xhigh) at Writing?
DeepSeek V4 Pro ranks #51 of 87 models on ToneBench through its best configuration, DeepSeek V4 Pro (high). This configuration is #106 of 151 configurations, in the bottom third of the board, with a Writing Elo of 1266 and a Writing Score of 73.1/100. The ranks come from full YouTube scripts written in the voice of Louis-François Bouchard and judged blind, with the channel's finished script as the reference. The benchmark measures long-form scripted writing, so the result does not carry over to every kind of text.
