I think you might be misunderstanding this? This is, from my understanding, what went down:
1. curl was scanned by many different things, including AISLE, and many bugs were fixed <- all this was in the past 2. curl a week ago was scanned again my Mythos and Codex Security, and both of them said: 0 issues found 3. the same curl was scanned by AISLE a day later, resulting in ~29 reports (based on the blog post and mastodon posts from Daniel Stenberg) 4. of these 29, 6 cleared the bar and got CVEs in curl 5. these 6 CVEs were just announced as fixed in curl 8.22.0 today, together with 4 more CVEs that were detected by other people prior to point 2. of this list
so imho it was head-to-head, the very same codebase => it's a legit comparison
Curl has been scanned by mythos and several other AI tools several times over the past year already. Mythos found nothing this round, but when it was first released it found issues which have been fixed - and several other AIs had already scanned curl for issues which had been fixed by then.
We can say that this is a useful tool, but is it better or worse than the others - there is no way to make that conclusion.
Edit, wait, are you claiming that asile was already used and those issues fixed, and it still found more. That is valid, but it only says that asile is better by enough that is worth an upgrade, while the others probably are not. It is not valid in comparing to other tools. (assuming this is true, I've never heard of asile before this)
