Slopus is no more

Claude Opus 4.8 -> 5 does a 20 point jump in AlmanBench and gets in the top 5

In the same league as GPT-5.6

Also 11 points higher than Sonnet 5

You know the performance gains are real (at least in multilingual singe-step reasoning) when you run a benchmark that you know that the labs aren't benchmaxxing on

A welcome change finally, for the Opus brand!
