Key Results
- StandingMiMo-V2.6-Pro ranks #25 of 87 models, and this is its only configuration on the board. As a configuration, it is #51 of 151 configurations by Writing Elo (1871), in the middle third of the board. Its 95% range (1829 to 1915) overlaps 24 other configurations, ranked #35 to #60.
- MetricsBest-ranked: Tone & Voice Match (78.0, 39th of 151 configurations, +3.9 against the board median). Lowest-ranked: Substance, Accuracy & Value (80.9, 83rd of 151 configurations, -0.9 against the board median).
- ScriptsFrom 78.0 on Script 4 (short explainer) to 82.5 on Script 9 (career guide): a 4.5-point spread across the 10 reference scripts.
- ConsistencyIts Writing Score moves ± 1.9 between drafts of the same script, against ± 2.5 for the median configuration: typical.
- ValueMiMo-V2.6-Flash (thinking on) ranks higher with an overlapping Elo range and costs about $0.0057 per script, against $0.017 per script for this one.
Louis's PickI'd pick DeepSeek V4.1 Flash 1017 (max) over this one: it 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).
Substance, Accuracy & Value ranks in the bottom half (83rd of 151 configurations), so check the facts and the depth before anything goes out.
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.
It outranks 62 configurations that cost at least 50% more.
Among proprietary models, MiMo-V2.6-Pro is 19th of 53. As a configuration, it is 42nd 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.

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 80.2 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.
Evaluation Setup
How this exact configuration was run and judged: route, model ID, dates, sampling and prompt.
- Accessed viaOpenRouter · model page ↗.
- Exact model / route id
xiaomi/mimo-v2.6-pro(the request sets no level; the provider applies thinking on). - 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).
