Which model each app runs today, and when it last changed

A default stated against a default that follows

Both entries answer the default question and only one of them states it. On one, the price list names the model and resolution an untouched project runs on. On the other, every plan carries the same house model, so the answer follows from the menu having one line. As of 2026-09-22.

Inclusion rule. Both cells on a row come from the entry's own priced pages. A default is recorded when the page states one, or when a single-model menu makes the answer follow. Order. How the answer is established first, then what it covers.

1A stated default is auditable; an implied one is merely true

Where a page names the starting model and version, two dated readings settle whether it moved. Where the answer follows from there being one line, a version change leaves no trace on the page at all.

Both entries genuinely answer the question. Only one of them will still answer it after the engine underneath has been replaced.

2Version granularity separates them

One entry prints a version beside each rate; the other prints a model name that has no public version string. So on one page an in-place update would be visible and on the other it would not.

That is the difference between detecting a swap and detecting a rename. The version question sets out why the second is much weaker evidence.

3Neither keeps an older line

Five current tiers and one house model both leave a production with nothing to fall back to when the engine moves. The five tiers spread the choice without deepening it.

Three entries in this register do list a previous generation. All three treat it as a menu rather than a commitment, which the succession column records entry by entry.
