I have noticed opus doing A/B testing since the performance varies greatly. While looking for jailbreaks I have discovered that if you put a neurotoxin chemical composition into your system prompt it will default to a specific variant of the model presumeably due to triggering some kind of safety. Might put you on a watchlist so ymmv.
