Picks and Verdict
PickGLM-5.3 Flash
GLM-5.3 Flash (max)
Pick GLM-5.3 Flash (max) for budget scripts that hold the requested length, since it takes all ten scripts here for $0.022.
PickMiMo-V2.6-Pro
MiMo-V2.6-Pro (thinking on)
Pick MiMo-V2.6-Pro (thinking on) when voice is what you care about most, since it matches GLM's 78.0 on Tone & Voice Match for $0.017 a script.
Both of these cost about two cents a script, so price decides nothing, and on the writing I'd take GLM-5.3 Flash. It's the #12 model of 78 and MiMo-V2.6-Pro is the #20 model, with 187 Elo between GLM-5.3 Flash (max) and MiMo-V2.6-Pro (thinking on) and 95% ranges that don't overlap. That's strong evidence for the order, and GLM also takes all ten scripts. Neither model has a second setting on the board, so there's no thinking ladder to compare. The closest thing is the reasoning token count: GLM spends more than three times as many as MiMo and still finishes a minute sooner, for half a cent more. On tone they score exactly the same, 78.0, which I didn't expect with a gap that size. GLM pulls ahead on length and the hook, about six points on Length Adherence and three on Hook Strength, with smaller leads on substance and YouTube best practices. MiMo is slightly ahead on slop and visual cues, a few tenths each, and that's too little to change my mind. For a budget script, GLM is the one I'd run.
Disclosure: GLM-5.3 Flash comes from the same lab as one of the four judges, GLM 5.3 Flash. The other three sit outside its lab, so it is never scored by its own lab alone (how the panel works). The judge analysis measures how much each judge favors its own lab.
How to Read the Writing Score, Writing Elo and 95% Ranges
Writing Score and Writing Elo. The Writing Score (0 to 100) is the weighted average of the nine metric scores: seven from the judges, Length Adherence from code and the Slop Score half from each. The Writing Elo is a rating from pairwise comparisons: on each script, each configuration's average across its drafts is compared with every other configuration's, and gaps within the draft-to-draft variation count as draws. Elo rewards winning often, so the two can put configurations in a different order.
Elo ranges. Each 95% range shows how far a configuration's Elo could move if the drafts had come out slightly differently. It comes from resampling every configuration's recorded draft scores on each reference script and ranking again. Comparing two separate ranges does not test the Elo gap between them: ranges far apart are strong evidence for the order, and overlapping ranges do not mean a tie. The reference scripts stay fixed, so the ranges say nothing about new scripts. The methodology page has the full description.
All Thinking Levels of Both Models
Every ranked configuration of GLM-5.3 Flash and MiMo-V2.6-Pro, scored on the same 10 scripts by the same four judges.
- Each row is one configuration: the model at one thinking level. The dot is its Writing Elo, a rating from pairwise comparisons of the scores on each script, and the bar is its 95% range: how far that Elo could move if the drafts had come out slightly differently.
- When two bars overlap, the board cannot order those two configurations. Bars far apart are strong evidence for the order.
- The table under the chart lists the same configurations in the same order and adds the Writing Score (the 0 to 100 consensus of the judges and code), cost, time and configuration rank (the place among all configurations on the board).
Shaded rows are the configurations chosen for the metric comparison below.
| Configuration | Writing Elo | 95% Range | Writing Score | Cost / Script | Time / Script | Reasoning Tokens | Configuration Rank |
|---|---|---|---|---|---|---|---|
| GLM-5.3 Flash (max) | 2140 | 2093 to 2186 | 81.8 | $0.022 | 5.2 min | 37,224 | #23 |
| MiMo-V2.6-Pro (thinking on) | 1953 | 1905 to 1997 | 80.2 | $0.017 | 6.2 min | 10,176 | #39 |
Cost is one script at the API list price of the route used, uncached and without judging. Time is the average for one accepted script, retries included.
Computed Findings Across Thinking Levels
Each finding is computed from the configurations above. Where two 95% ranges overlap, the board cannot order those two configurations.
- Best Configurations Head to Head. GLM-5.3 Flash (max) leads MiMo-V2.6-Pro (thinking on) by 187 Elo, and their 95% ranges do not overlap (2093 to 2186 against 1905 to 1997), which is strong evidence for that order.
Two Chosen Configurations Compared
Pick one configuration of each model to compare their metric scores, consistency across drafts and per-script scores. Each menu starts on the model's best configuration.
Scores by Metric
GLM-5.3 Flash (max) scores higher on six of the nine metrics and MiMo-V2.6-Pro (thinking on) on two, with one tie. Weighted by each metric's share of the Writing Score, Length Adherence does the most to put GLM-5.3 Flash (max) ahead, with a 6.2-point lead on that metric. The weight beside each metric is its share of the Writing Score.
Consistency Across Drafts
| GLM-5.3 Flash (max) | MiMo-V2.6-Pro (thinking on) | |
|---|---|---|
| Score spread across drafts (±) | 1.62 | 1.87 |
| Lowest script score | 80.3 Script 4 | 78.0 Script 4 |
| Highest script score | 83.8 Script 9 | 82.5 Script 9 |
| Range across scripts | 3.5 | 4.5 |
Spread is how much the Writing Score moves between a configuration's drafts, and lower is steadier. Green marks the better number in each row.

Nearby Match-Ups by Best Writing Elo
Every configuration wrote five drafts for each of the same 10 briefs, from the same prompt. Generation was closed-book, with the prompt as the only source and no web search or other tools. Each judge scores every draft once: Claude 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, a typed judge from TypeSafe that answers each metric as a multiple-choice question. The channel's finished script is their reference for the voice, and it gets no score on the board itself.
