Boris, you're seeing a ton of anecdotes here and Claude has done something that has affected a bunch of their most fervent users.
Jeff Bezos famously said that if the anecdotes are contradicting the metrics, then the metrics are measuring the wrong things. I suggest you take the anecdotes here seriously and figure out where/why the metrics are wrong.
We are taking it seriously, and are continuing to investigate. We are not trusting the metrics.
But the default 1M context window just rolled out a few weeks ago. If refreshing old sessions on 1M context windows is the problem, it's completely aligned with what Boris is saying.
On the subject of metrics, better user-facing metrics to understand and debug usage patterns would be a great addition. I'd love an easier way to understand the ave cost incurred by a specific skill, for example. (If I'm missing something obvious, let me know.)
Baking deeper analytics into CC would be helpful... similar to ccusage perhaps: https://github.com/ryoppippi/ccusage
