Anecdata point - I’ve been running for around 3-4 hours this morning constantly using Haiku and it hasn’t hit the limit - currently at 74% and it resets in 1.5 hours. I think it’s safe to say you get a fair bit more usage over Sonnet.

Still trying to judge the performance though - first impression is that it seems to make sudden approach changes for no real reason. For example - after compacting, the next task I gave it, it suddenly started trying to git commit after each task completion, did that for a while, then stopped again.
