I've definitely noticed 5.6 sol being extremely trigger happy in ways other models, even 5.5, we're not. I would definitely categorize a few small incidents at work where it performed "actions a reasonable user would likely not anticipate and strongly object to." Just my anecdotal experience.
For example discussing driver upgrade and subsequent password rotation and it didn't stop and ask me if I wanted to restart the service or install the driver or anything, it immediately took action. It feels like a side effect of pushing more "agency."
I like 5.5 a lot, despite how I feel about OpenAI as a company. In OpenCode it feels about as smart as Opus 4.8, but it's less aggressive about following up on minutiae and getting lost in side quests. Might be a matter of prompt design moreso than model capability. I was looking forward to 5.6 but now this thread is making me quickly lose interest.
I’m still using 5.5 and had it do almost exactly that same example on a task yesterday so doesn’t seem like a clear cut 5.5 vs 5.6 thing. It’s pretty trigger happy already once it gets any kind of “go” without specific restrictions.
