That viral Tweet was analyzing the summarizer output, not Opus output.
The reasoning traces aren't available. The summarizer gives a short summary of what the reasoning traces do.
The changes were in the summarizer model. The Tweet doesn't even say that Opus was nerfed, everyone just assumed it because the summarizer started using "I'm..." more.
This mystery was solved on Twitter over the weekend. Watching the pitchforks come out on Hacker News on Monday over a situation that was already resolved and debunked is starting to feel like how LinkedIn catches on to internet drama about a week later.
