Interesting timing to release this on the same day Jensen makes a statement on open source AI.

Really? It's better than Opus 4.8, that's the point.

When they release new versions of Sonnet, no-one expects them to be better than Opus.

Rather interesting that this makes sonnet 5 look even worse! There is no reason to use sonnet over opus with low or no reasoning at all.
