Unless you’re somehow on a different quota system, or maybe using Haiku, there’s no way you can sustain five continuous hours of parallel agents running without hitting the 5h quota limit, even on the 20x max plan. But maybe your company is flagged as VIP or something.

OK not constantly using multiple agents, but very frequently.

I suspect Anthropic flags accounts in their backend and different people are getting different limits. What criteria they flag with, I am not sure.

I would try to trim this suspicion with both Occam‘s and Hanlon‘s razor.
