I'd add the MR review use case.
I have limited success with feeding a LLM (dolphin finetune of mixtral) a content of a merge request coming from my team. It was few thousand lines of added integration test code and I just couldn't be bothered/had little time to really delve.
I slapped the diff and used about 10 prompt strategies to get anything meaningful. So my first initial impressions were: clearly it was finetuned on too short responses. It kept putting in "etc.", "and other input parameters", "and other relevant information". At one point I was ready to give up; it clearly hallucinated.
Or that's what I thought: turned out there was some new edge case of a existing functionality added that was added, without ever me noticing (despite being on the same meetings).
I think it actually saved me a lot of hours or pestering other team members.
