I'd be surprised if this was a new base model. It sounds like they just did some post-training RL tuning to make this version specifically stronger for coding, at the expense of other priorities.
Every frontier model now is a distill of a larger unpublished model. This could be a slightly smaller distill, with potentially the extra tuning you're mentioning.
That's an unsubstantiated claim. I doubt this is true, since people are disproportionately more willing to pay for the best of the best, rather than for something worse.
