OpenAI's GPT-5.5 matches Anthropic's Mythos in capability but costs up to five times less and is available through Amazon Bedrock for private corporate deployments. Anthropic's compute constraints limit its market reach, making GPT-5.5 a major shift for cost and security-conscious users.

OpenAI is doing just fine with all their decisions. 5.5 is equivalent to Mythos. That's my core belief. It is an unbelievable model and people are dramatically underreacting.
It's actually better than Mythos according to some of the cybersecurity benchmarks that are finding that it's hitting the same capability levels 5 times cheaper and actually generally available.
Yep. Look at what Expo has put out. They, they, they have early access, right? They're deep on this. 5.5 is unbelievable. Anthropic is compute constrained and that's why it's not going to market. Well, that's interesting.
5.5 is also available now on Amazon Bedrock. So you can get it inside a secure environment. So if, you know, for sensitive use, corporate use, you can keep your prompts and your results all secret from the provider. That's for the first time. That's only been like, what, a month now? Yeah. That, that's been available. But that's, that's a big game changer.
Okay. Well maybe that's a, yeah, that's huge.
I hadn't, I hadn't heard anyone say 5.5 is actually better, like as good as Mythos, which isn't available yet.
