So many posts lately about people hitting their Claude Pro limits after just 2 - 3 messages, while others seem to have “unlimited” access. Most people say it’s AB testing, and maybe it is, but what about Timezones and the US sleep cycle? Last night (12 AM – 3 AM CET), I was working with Opus on a heavy codebase and got 15 - 20 prompts as a PRO (20$) with 4 chat compressions before the 5 hour Rate Limit. Fast forward to 1 PM CET today: same project, same files, but I got hit by the rate limit after exactly 2 messages also with Opus. It seems like Anthropic’s “dynamic limits” are heavily tied to US peak hours. When the US is asleep, users in Europe or Asia seem to get the “surplus” capacity, leading to much higher limits. The moment the US East Coast wakes up, the throttling for everyone else gets aggressive to save resources. So while the Rate Limit has heavily increased in peak hours, it still feels “normal” like a month ago outside those peak hours. That could be the reason why many say, that they have no issues with Rate Limits at all (in good timezones), while others get Rate limited after 2 prompts. submitted by /u/Revolutionary_Mine29
