Steps to Reproduce

Claude Opus used to accept up to 25000 tokens per file. The model quality degraded absurdly in the last days and now my eyes caught some error messages saying that the max token limit per file is 10000.

I cannot find any controls to get back to 25000.

If you search on the issues on this Github page you see the last issue with mentions 25000 tokens is 7 days ago, while 10000 is like 1h.

Yeah, that was a silent downgrade.

For my workload Claude cannot generate code that I trust. The back and forth during conde reviews became extremely tiresome in the last 7 days at the point I'm almost giving up.
