After having seen Sonnet 4.5 build a fantastic, functional web app 7-8 months ago, it is very surprising to see Opus 4.8 (whose task in this case was to curate a daily newsletter) hallucinate its sources. For context, I was asking it for d…

I've run out of Opus credits, but when I try to use Sonnet as a models, I get the message “You've hit your weekly limit.” Yet, as you can see, I still have quite a few “weekly Sonnet” credits left?? Does anyone know if this is normal?

Hi everyone, I’m working on a research paper where we previously used Claude Sonnet 4 as the backbone. We now need to run additional experiments with the same model, but it has been marked as a legacy model.
