I was doing some fairly heavy development on Flash 1017 yesterday for around ~3 hours on pi, and all told that session ran about $0.40. I probably could've saved myself more if I'd compacted the context more frequently, since at one point I was running 300k tok context requests.

But it accomplished everything I was looking for it to do, even if Claude perhaps could've done it with less guidance on my part/faster. I'm pretty impressed with it's performance.
