Until 4 October 2026 the September and October 2026 records were offered for download under CC BY 4.0; copies obtained then keep those terms. From that date no edition's raw labels or full responses are offered for download; they are sent on request, under the record license: for the research or reporting it was sent for, with commercial use, redistribution and model training by agreement. The data dictionary, what each column means and how to reproduce any share on the site, is published above.
The app reads this record for one company: every category it is named in, across all four indexes, what changed, who the models pick instead, and every answer behind every figure.

|---|---|
| The flagship models | Claude Opus 5, Claude Opus 4.8, GPT-6 Astra, GPT-5.6 Sol, Gemini 3.1 Pro, Perplexity Sonar Pro, Muse Spark 1.3, on your category every month. |
| Job-to-be-done framing | A seventh prompt per category that describes the work instead of naming the category. |
Prices are on the Subscribe page. A cut that enough subscribers ask for can be promoted into the public index; that is announced in the edition log above and on the method page's change log, never done quietly.
A category enters the addressable set when it is a product a buyer asks an AI to recommend for going to market. Additions and removals are announced in the edition log and on the method page, never done quietly.
Every prompt set is one combination of four choices: how big the buyer is, what industry it is in, how the question is framed, and who answers. Each added value multiplies the prompt set, so these are taxonomy decisions first and scope decisions second.
A monthly edition on the same date. A special edition within days of a major frontier release, published against the prior generation. Quarterly written analysis, only once enough editions have accumulated to say something with substance.
When the vendor table changes, every edition in the series is regenerated under the new version, so the series is never a mix of table versions. A trend that appears only after a table change is tooling, not model behavior.
The historical series is the part that gets harder to replicate the longer it runs. Every edition stays at its stable URL, and the final edition is marked final on the site.
