## Claude models, across 115 settled listings

Of the 115 Published listings whose datasheet settles “Claude models”, the largest group is “Yes” at 57 (50%). Measured 2026-09-09.

| --- | --- | --- |
| Yes | 57 | 50% |
| Qualified | 34 | 30% |
| No | 20 | 17% |
| Does not apply | 2 | 2% |
| Not established | 2 | 2% |

Denominator: 115 Published listings whose datasheet settles “Claude models”. Method: Counted from the stored datasheet answer for “Claude models” across every Published listing, all of which have a recognised stored answer on that row.

## The population

115 listings in this index are Published. This is the population as of 2026-09-09. 115 of the 115 published listings in this index carry a settled answer for “Claude models”. That row asks: Does it run on Claude? Every listing in the index is settled on this row, so nothing is left out.

## Findings

1. 57 of the 115 settled listings answer “Yes” for “Claude models”. That is 50% of the settled set.

2. 34 of the 115 settled listings answer “Qualified” for “Claude models”. That is 30% of the settled set.

3. 20 of the 115 settled listings answer “No” for “Claude models”. That is 17% of the settled set.

4. 2 of the 115 settled listings answer “Does not apply” for “Claude models”. That is 2% of the settled set.

5. 2 of the 115 settled listings answer “Not established” for “Claude models”. That is 2% of the settled set.

1 of those yes answers is Rankscale, which still answers yes for “Claude models”. Its [listing](/rankscale) carries the stored answer and links to [the source recorded for it](https://rankscale.ai/pricing). This is one worked example, not an independent audit of every source in the census.

## What we counted, and how

Each figure above is a count over the “Claude models” row of the listing datasheet, taken from the same stored answer the listing page renders. The denominator is the 115 listings whose answer is settled, meaning one of yes, qualified, no, does not apply, not established. On this row that is the whole index, because every listing has a recognised stored answer. Every number here is stored with the read-only query that reproduces it and re-run every sixty seconds against the live corpus, so a figure that stops reproducing surfaces as drift rather than as a stale sentence nobody notices. Our full method covers how a datasheet row is settled in the first place.

## Limitations

This counts stored datasheet answers, not independently tested capabilities. A sourced answer can record a vendor statement or our reading of published evidence; this census does not re-fetch those sources. “Not established” means we have not established an answer. That can reflect vendor nondisclosure, blocked evidence, or unfinished research, not a no. An absent or unrecognised answer is excluded rather than treated as a researched finding. The figures are restated when the stored corpus changes; the date above is the count used for this published version, not a new verification of the vendors.
