Thanks, that's useful! We did use ChatGPT 5.5 for some time and it did perform pretty well too (of course more expensive than GLM 5.2). We tried Claude 4.7 and 4.8, but we found both models to be "lazy" and very expensive. Claude would always rather prefer the route of saying that the evidence was not found or something is incomplete, rather than put more effort into finding/repairing the particular issue.
