Picks and Verdict
PickDeepSeek V4.1 Flash
DeepSeek V4.1 Flash (max)
Pick DeepSeek V4.1 Flash (max) as the cheap all-rounder, at $0.017 a script with a range that overlaps Grok 4.6's and open weights.
PickGrok 4.6
Grok 4.6 (high)
Pick Grok 4.6 (high) for fact-heavy explainers, since its 85.0 on Substance, Accuracy & Value beats every DeepSeek setting.
The board can't tell these two apart on writing, and one of them costs about nine times as much. Ranked by best setting, DeepSeek V4.1 Flash is #14 of 78 models and Grok 4.6 is the #19 model. DeepSeek V4.1 Flash (max) sits 62 Elo ahead of Grok 4.6 (high), with overlapping 95% ranges. Grok's bill is $0.156 a script against $0.017, and DeepSeek finishes in under half the time. At high, the one level name they share, Grok has the higher Elo, 1978 against 1971. Those ranges overlap too, and DeepSeek V4.1 Flash (high) costs about a cent. Below that DeepSeek drops out, with its low setting under Grok and the ranges apart. To be fair to Grok, it leads on substance by two and a half points and on tone and visual cues by about a point each. DeepSeek answers on craft, four points up, and on length, about five, with drafts that vary less between runs. With the writing this close, I'd take the one that costs under two cents: DeepSeek at max. Its open weights count too.
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 DeepSeek V4.1 Flash and Grok 4.6, 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 |
|---|---|---|---|---|---|---|---|
| DeepSeek V4.1 Flash (max) | 2040 | 1999 to 2076 | 81.0 | $0.017 | 2.4 min | 22,010 | #28 |

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. DeepSeek V4.1 Flash (max) at Elo 2040 (range 1999 to 2076) and Grok 4.6 (high) at Elo 1978 (range 1930 to 2023) have overlapping 95% ranges, so the board cannot separate the two best configurations.
- Same Level Name, Side by Side. At high, the one level name both models use, Grok 4.6 has the higher Writing Elo: 1978 against 1971. Their 95% ranges overlap there. Level names come from each provider, so the same name does not promise the same reasoning budget.
- Cheapest Configuration Overlapping the Top One. DeepSeek V4.1 Flash (high), at $0.012 per script, is the cheapest configuration whose 95% range overlaps that of DeepSeek V4.1 Flash (max), at $0.017 per script: 1925 to 2010 against 1999 to 2076, so the board cannot separate them. DeepSeek V4.1 Flash (max) costs about 1.4 times as much per script.
- Cheapest DeepSeek V4.1 Flash Configuration Above Grok 4.6's Best. The cheapest DeepSeek V4.1 Flash configuration with a higher Writing Elo than Grok 4.6 (high), at Elo 1978 and $0.156 per script, is DeepSeek V4.1 Flash (max), at Elo 2040 and $0.017 per script. Their 95% ranges overlap, so the board cannot separate them. It costs less than the configuration it beats.
- Lowest to Highest Thinking Level. DeepSeek V4.1 Flash moves +402 Elo from no thinking to max, at about 4.6 times the cost per script.

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.
