4.7 and 4.8 are less helpful as assistants than 4.6 because they push to finish tasks instead of holding a conversation.
4.6 worked better for their vibe coding because 4.7 went beyond the request and added features they had not asked for.
4.7 broke a simple abstraction, so they set a permanent override to run 4.6 instead.
4.7 was worse than 4.6 on every third-party harness and on Bedrock, based on their experience and colleagues' reports.

I switched from Opus 4.6 -> Opus 4.7 -> GPT 5.5 and tried Flash 3.5 tonight and I was not impressed. It is straight up unreliable, e.g. deleting code and forgetting to add the new stuff it was asked to, then happily marking the task as complete with up-beat conclusion. I personally appreciate GPT 5.5 toned-down, objective style so really dislike how this model feels. I get that it's a flash model and not in the same league as GPT 5.5 but their marketing suggest otherwise so thy are just setting themselves up for disappointment.
4.7 seems slightly smarter than 4.6 for their math proof and coding work.
