Today was the most productive coding day I’ve had in 10 years.
I spent 1.6k out of the 10k credits Cursor gave me, mainly using Opus 4.7 1M Max and GPT-5.5 Extra High Fast. The takeaway is simple. In Cursor these models feel unusually well tuned, fast, precise, and reliable for real work.
Here’s what I got done in a single day:
1. Built the iOS version of MiaoYan from scratch with iPad support, including preview and iCloud sync
2. Fully implemented payments in the Mole macOS client and shipped the V1 website
3. Wrapped up Kaku macOS terminal v0.10, polishing AI chat and many details
4. Shipped a major upgrade to Kami typesetting system, fixing PPT support and many edge cases
5. Upgraded my Luo Chinese font project with a new learning mode and overall improvements
6. Improved Mole CLI with better performance, fallbacks, and a lot of detail work
There was also a lot more small work in between.
What stood out is strong context handling, solid multi file edits, and stable long chain execution. It feels like a real collaborator.
As a long time builder and a TSLA shareholder, I’m excited to see Cursor keep improving. Thanks again @cursor_ai @edwinarbus for the 10k credits, I will keep putting them to good use.
