Anthropic has been sitting on Mythos for a while now. I guess they don't feel pressured to fuck it ship it until anyone else gets a 10T to work.

According to people who have access to Mythos, it is slightly worse than GPT-5.5-xhigh. At least for security tasks.
Hold on, I think this claim needs some hard data. Here you go gentlemen:

See the later post testing a newer Mythos checkpoint, though: https://www.aisi.gov.uk/blog/how-fast-is-autonomous-ai-cyber...
Fair enough
That claim keeps contradicted hard by other parties, who say Mythos beats 5.5 resoundingly on both autonomous search and discovery and creation of complex exploit chains.
There might be a harness difference, but also, this CTF-type benchmark might not capture the capability difference fully.

Anthropic can sell Mythos to Fortune 500 companies and bypass the average user. I'm not sure how much is hype but I see things like this https://blog.cloudflare.com/cyber-frontier-models/
It's doubtful they have the compute to make mythos publicly available even after the SpaceX datacenter deal. And why sell it publicly if people are still willing to pay for Opus 4.7?
I suspect that Mythos doesn't have a business model that works
