100-word summary

Alibaba's DingTalk unveiled an AI operating system that automates grunt work inside enterprise chat. The standout demo: an AI grader that processes 100 papers every four minutes with 99% accuracy. A data annotation tool cuts human involvement from 100% to 20%, tripling efficiency. Order processing hit 100% accuracy in tests. The platform, called DEAP, lets companies build custom AI agents for specific tasks (recruiting, travel booking, printing) and train models for about $0.35, with follow-up tasks costing pennies. The catch? DingTalk didn't disclose sample sizes or how long these numbers hold up in the real world. If the speed holds, grading season just got a lot shorter.
