This is where I’m at, too. The o3 limits were more restrictive than the 5-thinking limits are now, but I regularly used o4-mini-high for complex-but-not-brain-breaking questions and was quite happy with the result. Now I have to choose between saving my usage with 5, which so far hasn’t felt up to the more complex use cases, or burn usage much faster with 5-thinking.

I suppose this is probably the point. I’m still not super keen on ponying up 200 bucks a month, but it’s more likely now.
