Key Results
StandingGPT-5.5 ranks #41 of 87 models through its best configuration, GPT-5.5 (xhigh). This setting is #97 of 151 configurations by Writing Elo (1421), in the middle third of the board. Its 95% range (1369 to 1476) overlaps 14 other configurations, ranked #88 to #103.
MetricsBest-ranked: Tone & Voice Match (78.3, 33rd of 151 configurations, +4.2 against the board median). Lowest-ranked: Length Adherence (33.1, 145th of 151 configurations, -51.7 against the board median).
ScriptsFrom 71.8 on Script 4 (short explainer) to 79.8 on Script 9 (career guide): a 8.0-point spread across the 10 reference scripts.
ConsistencyIts Writing Score moves ± 2.8 between drafts of the same script, against ± 2.5 for the median configuration: typical.
ValueGPT-6 Luna (medium) ranks higher and costs about $0.0026 per script, against $0.174 per script for this one.
Louis's PickI'd pay about 1 cent more per script for GPT-5.5 (xhigh).
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 Tone & Voice Match, its best-ranked metric, its drafts sound closer to Louis's voice than the typical configuration's. Length Adherence ranks in the bottom half (145th of 151 configurations), so plan on trimming or padding to reach the target length.
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.
Among proprietary models, GPT-5.5 is 33rd of 53. This setting is 82nd of 108 proprietary configurations. The best open-weight configuration, GLM-5.3 (max) at configuration #22, 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: ± 10.5 between drafts against ± 6.6, 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 75.2 combines their scores with the parts computed in code (Length Adherence and half of the Slop Score). The highest and lowest judge are 12.9 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.

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 GPT-5.5 (none) at Writing?
GPT-5.5 ranks #41 of 87 models on ToneBench through its best configuration, GPT-5.5 (xhigh). This configuration is #97 of 151 configurations, in the middle third of the board, with a Writing Elo of 1421 and a Writing Score of 75.2/100. 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.
Is GPT-5.5 (none) the Best OpenAI Model for Writing?
No. GPT-5.5 is 9th of 13 OpenAI models. The top one is GPT-6 Sol, through GPT-6 Sol (max), about 880 Elo ahead of this setting.
Is GPT-5.5 (none) Good Value for the Money?
It costs about $0.174 per script. GPT-6 Luna (medium) ranks higher and costs less.
What Are the Strengths and Weaknesses of GPT-5.5 (none)?
Its best-ranked metric is Tone & Voice Match (78.3, 33rd of 151 configurations, +4.2 against the board median), and its lowest-ranked is Length Adherence (33.1, 145th of 151, -51.7). The Scores by Metric section shows the board median and the board's best for each one.
How Was GPT-5.5 (none) Evaluated?
It was run through the Codex CLI (OpenAI subscription), with the exact model/route ID gpt-5.5 at reasoning effort none, first run on 2026-10-11. It wrote each script 5 times with the provider's default sampling and no fine-tuning. The Evaluation Setup section and the methodology page have the details.
Does GPT-5.5 (none) Have Open Weights?
No. It is a proprietary model: its weights are not public. Among proprietary configurations it is 82nd of 108 for writing.
