## 正文

✔️Hy4 preview just shipped an upgrade.
You flagged it: long thinking + over-verification on complex tasks.
We optimized it. Now live for everyone.
Same task quality. Fewer turns. Lower in/out tokens.
Bench + human eval both confirm.
We’ll keep iterating fast. Try it and tell us what still breaks.
