Small gap · B scored lower
Same benchmark workload
High
We describe gaps under 1 point as small, 1–under 5 as noticeable, and 5 or more as large. These are reading aids, not proof that a difference would hold up in repeated tests. Equal scores can still hide different mistakes.

What would A versus B cost if you repeated this benchmark’s average workload?
A source-workload scenario using average measured USD costs. Source prices, caching and tools are already reflected in those observed costs. Your agent’s costs may differ.
Estimate the extra bill from thinking tokens. The starting token counts are editable examples, not measurements of Grok 4.6. Rates start from the current model snapshot.
Mode B costs $24 more per month with these assumptions.
This estimate uses the token counts and prices you enter. Excludes retries, tools, caching, long-context premiums, hosting and taxes. Includes thinking in output billing; do not also include it in “visible output.” Check endpoint limits separately. Changing mode does not automatically predict tokens or quality.
Each card compares settings tested together in one study. Scores from different benchmarks or question sets measure different work and are not averaged together.

Near-best pick: High within 1 point of the best score. Highest-to-lowest score gap: 9.2 points.

High is the lowest-cost option within 1 point of the best intelligence index in Artificial Analysis. Extra high trails the best tested score by 0.1 points. This allows a score up to 1 point below the best result in the first listed study. Change the study, task and allowed score gap above to explore another comparison. It is a shortlist for testing your own workload.
Low, Medium, High, Extra high appear in the collected studies. Each chart only includes modes tested together in that study. These published labels do not establish that every endpoint or application exposes every setting.
In Artificial Analysis, High to Extra high lowers the observed score by 0.1 points. The overall tested range is 9.2 points. These are observed differences, not proof that extra thinking caused the decline.
Use the A/B selector and measured-cost calculator when the source reports dollar costs. For your own agent, enter average input, visible output and thinking tokens in the token calculator. Higher effort is adaptive, so the label itself cannot tell you the bill. Missing costs stay missing.
