Description
Description
So I had GPT-5.6 Sol (medium) producing a review of a PR. It did a wonderful job and then left an excellent review comment on the PR.
However, it then immediately began producing garbled output after the comment and in its final message to me. I switched the variant to GPT-5.6 Sol (low), and suddenly it was cohesive again.
I have no idea what caused it, but ChatGPT reckons that the streaming was mangled by the tool call (see screenshot).
As GPT would say: Ensure no weird. Need not glitch! Let's craft.
