The patch notes say:
Sonnet 3.7 thinking: We’ve made a few improvements to 3.7 prompting. Thinking will now cost 2 requests instead of 1. More improvements will be rolling out in the coming days.
How do I use the old way of 3.7 prompting which only uses 1 request? Like, the old way was completely fine, and now I’m getting charged for something that is simply the same to me but costs 100% more!
