Claude Opus 5.5 just beats Mythos 5.1. The model you can actually use just passed the model you mostly can’t, That is the quiet part of today’s system card: the cheaper public model is now sitting on the same internal capability line as the restricted frontier one. Capability is compounding. Price is falling, Access is still uneven.
