Opus 5.5 is the new #1 on CADArena.
We added six new models. Opus 5.5 scores 0.750 and takes the top spot from GPT-6 Astra (0.671).
And Grok 4.7 scores below Grok 4.6 and GPT-6 Luna.
I think this marks the beginning of the end for native CAD platforms.
My instinct is that the moat will move towards the PLM/PDM as a system of record (arena/solidworks PDM) + CAD kernel licensing (at least until mythos 2 or aeon is able to make a better version)
I am curious
