Is there any evidence Mythos is qualitatively better than the Opus 4.x?

I'm afraid that the usual mantra that "we just need more scale" that worked well for attracting investments, is not working anymore - bigger models provide marginal improvements while naturally get much more expensive to run.

Is this why both Anthropic and OpenAI are rushing for IPOs this year?

From what I've read so far it's less about Mythos being much better at tasks in isolation.

Security wise, it's about being able to find and chain multiple vulnerabilities to actually create viable exploits.

So I would imagine that if you were using it for regular software development you may not feel that it's that different unless used in a particular way?
