YacineMTB argues that GPT 5.5 (likely a typo) surpasses Anthropic's Opus models, suggesting users are switching away from Opus. Dylan Field criticizes Opus 4.8 for degraded curiosity and increased sycophancy.

If this keeps up, everyone is going to switch to got 5.5 if they haven’t already. It really seems like if you are still using opus, you are simply just incapable of telling the difference. I’m just shocked at how big the gap is myself. Is anthropic done for?

Dylan Field (@zoink): Opus 4.8 is a very strange model. Clearly Anthropic tried to improve honesty, which is commendable. However, the model’s curiosity (already worse in 4.7) degraded further. Result is a judgmental personality + sycophancy + sooo much hedging. Basically the opposite of Opus 3.
