Claude Opus 5 has been nerfed.
This is it losing to DeepSeek V4.1 Flash on BridgeBench.
The same model I put in A tier a month ago rendered a white screen. DeepSeek made an actual ocean sunset for 3 cents.
Claude Opus 5 cost 20x more and produced nothing.
This model is not the same model that launched in July. Anthropic has quietly degraded it, and at this point it is terrible.
We need Opus 5.1. Badly.
