I think the cyber concern is legitimate but the framing is still very capabilities-centric. The more interesting thing about the Mythos situation is that Anthropic's mitigation strategy is entirely structural, they'll give defenders early access so they get a head start. Instead of them orchestrating an alignment intervention or capabilities restriction, they're sequencing Mythos's deployment. Who gets access, when, under what conditions. The model itself is dual-use by nature; the same capability that finds vulnerabilities for defenders finds them for att... (read more)
I personally find it quite ironic that a company whose model represents "unprecedented cybersecurity risks" exposed the model's existence via a basic CMS misconfiguration, lol.
In any case, I imagine the per-token cost to be way higher than Opus 4.6, I wonder how usage windows will change after it gets deployed to the public

If it's the next level of pretraining compared to Opus 4 and Gemini 3 Pro, there's potential for novel observations about what that does to the texture of capabilities. It's the kind of thing that will predictably scale further soon without requiring algorithmic breakthroughs, and it's not even clear that RLVR can be expected to deliver more phase changes in capabilities in the near future due to pure scaling than pretraining (even if it's less than 1 phase change for either in expectation, until 2032 or so).
