It's a real dud IMO, worse than 4.6. I told it to fix a depth-testing issue with a WebGL scene and provided it a screenshot: told me it was fixed but it wasn't. I tell it to try again and it says it's "FOUND THE ROOT CAUSE!" then hasn't fixed it.

I told it to compose an image (putting headgear on top of a head) - kept getting it completely wrong, generating new headgear, getting that wrong and screwing up the scaling.

I told it to diagnose a webhook issue that was happening in production from a local environment and it kept giving me moronic answers like that environment variables weren't set (despite me telling it that the values WERE set in production).
