Staff engineer @Uber. I study where AI agents fail when the answer has to be right. Debugging, verification, reliability. Views my own.

Built an outage investigation agent with Jev: ~5 s per incident, vs 32 and 119 s for general-purpose LLMs.

Right service 57/60 times, but often without checking what failed.

How do you check that an AI agent actually did the work, not just got lucky? https://t.co/iu0tPbwoaV

@akacoding Thanks, I will try

came to X to share serious engineering stuff.

40+ posts, 8 followers. thought maybe reach was the problem, so i boosted a post 😅

same destination, took the toll road 🥲

[Minglei @rae1101x]

@akacoding Does it work better?

[Minglei @rae1101x]

@TypeLLM this is interesting. i’m building TypeRCA around incident investigation using decision models and currently it supports Jev, and I think it could be a good real-world place to test TypeLLM too. happy to try it

[Minglei @rae1101x]

@BabaDev_ Yes hehe no time to 😴
