Reading the chart
In Finder, choose a starting model and reasoning level. The selected setting sits at zero: alternatives are positioned by their change in index score horizontally and cost vertically. Click another model to make it the reference. Within lab is the default; choose Across labs and select labs or models to change the comparison pool. Budget bands and recommendations update for that pool.
Each arrow shows rounded percentage changes in index score (🧠) and cost ($). Hover for the model, lab, reasoning level, source values and precise changes. Solid arrows stay within a lab; dashed arrows cross labs and use the destination lab’s colour. The cost bands are spaced for readability, so use the printed percentages for the actual cost comparison.
Each budget band names the highest index score affordable at that benchmark-task budget among the selected models. It does not identify the best model for every task.
Price–score connects each model’s measured reasoning levels on a chart with a logarithmic cost axis. Reasoning compares index scores and task costs across measured effort settings. Only measured settings are shown; Sonnet and Opus use Default Fallback measurements.
What the numbers mean
The Intelligence Index combines results from several evaluations. A percentage change is a relative change in that aggregate score, not a percentage change in task accuracy. A 5% index change has no universal conversion into improvement on your own work.
Cost is the estimated US dollar cost per Intelligence Index benchmark task, including input, cache, reasoning and answer tokens. It is not subscription usage or a quote for your task. See the Artificial Analysis methodology and the chart’s model sources for details.
The chart uses an Artificial Analysis snapshot from 26 October 2026, not a live feed. It includes 15 model families and 48 settings. Two settings, Gemini 3.8 Flash Low and Muse Wonder Full Maximum, have scores but no reported cost; price comparisons exclude them.
