At $work we still have some places using Opus 4.5. Even places using Qwen 2.5-VL, which is now 18 months old. It works, and upgrading is work (we'd have to validate the new model performs comparable in all the corner cases that currently work just fine)

Those kind of workloads would be hit by an end of introductory pricing. And it's exactly the kind of cases that are not very price sensitive. Where we are price sensitive we track new model releases closely, where we aren't other issues get priority as long as llm performance is good enough
