alt Hacker News> On March 26, we shipped a change to clear Claude's older thinking from sessions that had been idle for over an hour, to reduce latency when users resumed those sessions. A bug caused this to keep happening every turn for the rest of the session instead of just once, which made Claude seem forgetful and repetitive. We fixed it on April 10. This affected Sonnet 4.6 and Opus 4.6.
Is it just me or does this seem kind of shocking? Such a severe bug affecting millions of users with a non-trivial effect on the context window that should be readily evident to anyone looking at the analytics. Makes me wonder if this is the result of Anthropic's vibe-coding culture. No one's actually looking at the product, its code, or its outputs?

I think that would also have busted cache all the time, and uncached requests consume usage limits rapidly.
It's really hard to understand. There needs to be really loud batman sign in the sky type signals from some hero third party calling out objective product degradation. Do they use cc internally? If so do they use a different version? This should've been almost as loud a break as service just going down altogether, yet it took 2 weeks to fix?!
