Picks and Verdict
PickGPT-5.6 Sol
GPT-5.6 Sol (low)
Pick GPT-5.6 Sol (low) when you want the draft in about a minute, since it costs $0.113 and the board can't separate ultra from it.
PickGrok 4.7
Grok 4.7 (medium)
Pick Grok 4.7 (medium) if you want Grok's voice, since it rates above high for $0.215 a script and holds Length Adherence at 78.7 where low drops to 68.8.
Grok 4.7 needs more thinking to get closer to the requested length. Length Adherence goes from 68.8 at low to 78.7 at medium, and the Elo climbs 90 points, for more than three times the cost. High costs more and rates 27 Elo below medium, with overlapping ranges, so the best setting is Grok 4.7 (medium), at $0.215 a script and about six minutes. GPT-5.6 Sol (low) costs $0.113, takes about a minute and sits 294 Elo higher, with separate 95% ranges. So Sol's cheapest setting beats Grok's best for about half the price, the #8 model of 78 against the #22 model, each ranked by its best setting. I wouldn't pay for Sol at ultra either: it sits 5 Elo below low, the two ranges overlap, and it takes more than four times as long. In fairness, all three Grok settings stay within a couple of tenths of Sol at low on Tone & Voice Match, the metric with the most weight. That doesn't make up for the prose: Grok at medium trails Sol at low by more than seven points on craft. My pick is Sol at low.
Disclosure: GPT-5.6 Sol comes from the same lab as one of the four judges, GPT-6.1 Sol. 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 GPT-5.6 Sol and Grok 4.7, 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 |
|---|---|---|---|---|---|---|---|
| GPT-5.6 Sol (low) | 2218 | 2181 to 2251 | 82.3 | $0.113 | 0.9 min | N/A | #16 |
| GPT-5.6 Sol (ultra) | 2213 | 2173 to 2266 | 82.3 | $0.367 | 4.1 min | N/A | #18 |
| Grok 4.7 (medium) | 1924 | 1863 to 1974 | 79.6 | $0.215 | 6.2 min | 27,687 | #42 |
| Grok 4.7 (high) | 1897 | 1850 to 1939 | 79.6 | $0.305 | 9.6 min | 42,549 | #43 |
| Grok 4.7 (low) | 1834 | 1784 to 1890 | 79.0 | $0.064 | 1.7 min | 2,760 | #48 |
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. N/A under Reasoning Tokens means the board has no separate reasoning count for that route.
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. GPT-5.6 Sol (low) leads Grok 4.7 (medium) by 294 Elo, and their 95% ranges do not overlap (2181 to 2251 against 1863 to 1974), which is strong evidence for that order.
- Every GPT-5.6 Sol Configuration Ranks Higher. Both GPT-5.6 Sol configurations rank above all three Grok 4.7 configurations: the lowest-rated, GPT-5.6 Sol (ultra) at Elo 2213, still beats Grok 4.7 (medium) at Elo 1924. Their 95% ranges do not overlap.
- Lowest Thinking Levels Head to Head. At their lowest thinking levels, GPT-5.6 Sol (low) at Elo 2218 and $0.113 per script leads Grok 4.7 (low) at Elo 1834 and $0.064 per script by 384 Elo. Their 95% ranges do not overlap.
- Same Level Name, Side by Side. At low, the one level name both models use, GPT-5.6 Sol has the higher Writing Elo: 2218 against 1834. Their 95% ranges do not overlap there. Level names come from each provider, so the same name does not promise the same reasoning budget.
- Cheapest GPT-5.6 Sol Configuration Above Grok 4.7's Best. The cheapest GPT-5.6 Sol configuration with a higher Writing Elo than Grok 4.7 (medium), at Elo 1924 and $0.215 per script, is GPT-5.6 Sol (low), at Elo 2218 and $0.113 per script. It costs less than the configuration it beats.
- Lowest to Highest Thinking Level. GPT-5.6 Sol moves -5 Elo from low to ultra, at about 3.2 times the cost per script. Grok 4.7 moves +63 Elo from low to high, at about 4.8 times the cost per script.

Scores by Metric
GPT-5.6 Sol (low) scores higher on eight of the nine metrics and Grok 4.7 (medium) on one. Weighted by each metric's share of the Writing Score, Writing Craft & Clarity does the most to put GPT-5.6 Sol (low) ahead, with a 7.4-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.
