Picks and Verdict

PickGLM-5.3

GLM-5.3 (max)

Pick GLM-5.3 (max) for anything going on the channel, since 233 Elo and a much closer length are worth $0.240.

PickMiMo-V2.6-Flash

MiMo-V2.6-Flash (thinking on)

Pick MiMo-V2.6-Flash (thinking on) for volume, at $0.0057 a script with hooks within a point of GLM's.

GLM-5.3 costs about 42 times as much per script as MiMo-V2.6-Flash, $0.240 against $0.0057, and each has a single setting on the board, so price against quality is the whole trade. GLM-5.3 (max) sits 233 Elo above MiMo-V2.6-Flash (thinking on), and their 95% ranges don't come close: the #7 model of 78 against the #18 model, each ranked by its best setting. GLM wins all ten scripts and eight of the nine metrics, though most of those leads are small. The big one is length, almost seven points. Tone, substance and YouTube structure follow at two to three points each. On hooks and craft they're within a point, and MiMo has the better Slop Score. GLM also spends about four times the reasoning tokens and two and a half more minutes on each script. For a single script that has to be right, a quarter is nothing and I'd take GLM. For a pile of rough drafts, I'd run MiMo and fix the length myself.

Disclosure: GLM-5.3 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 and MiMo-V2.6-Flash, scored on the same 10 scripts by the same four judges.

How to Read the Chart
  • 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).

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.

Scores by Metric

GLM-5.3 (max)MiMo-V2.6-Flash (thinking on)Solid bar: higher score in that row

GLM-5.3 (max) scores higher on eight of the nine metrics and MiMo-V2.6-Flash (thinking on) on one. Weighted by each metric's share of the Writing Score, Length Adherence does the most to put GLM-5.3 (max) ahead, with a 6.7-point lead on that metric. The weight beside each metric is its share of the Writing Score.

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.
