I've also noticed Sonnet starting to degrade. It's developing some of the behaviours that put me off the competition in the first place. Needless explanations, filler in responses, wanting to put everything in lists, even increased sycophancy.
I get that it's not an easy problem to solve, but how is Anthropic supposed to solve the actual alignment problem if they can't even stop their production LLMs from glazing the user all the time? And OpenAI is somehow even worse.
