An Anthropic model that has not been released yet surfaced on Chinese API proxies before its launch.

per the leak, Oceanus is priced at an insane $16/M input and $80/M output tokens—nearly 3x more expensive than Claude Opus.

The model is codenamed Oceanus and belongs to the upcoming Mythos release.

It was leaked, repackaged, and sold before Anthropic completed safety testing.

@rohanpaul_ai Insane that they have world class models but can't prevent leaks.

Also mythos was supposed to be much more expensive than that, I wonder what this model might be as it's not mythos 100%

@rohanpaul_ai If real, this is the two-speed market in a single line item. Open models at sub-$5/M output, frontier at $80. The deflation is real, it's just quarantined at the commodity layer. Frontier keeps climbing. Wrote the math:

@rohanpaul_ai This just shows how much of vibecoding they are using when coding.

If they can't secure a world-class model from leaking, how are they supposed to even keep going for the next 3+ years?

@rohanpaul_ai So Oceanus is leaked, untested, *and* triple Opus pricing? Peak AI industry plot twist. 💡

@rohanpaul_ai Some red teamers proxied to some Chinese proxy. No model weights or internal code was actually leaked.

@rohanpaul_ai “Leaked” is doing a lot of laundering here.

This looks less like a mystery and more like the same old failure mode:

the model was gated, the route was not, and the proxy market found the door before the safety team finished checking the lock. 🛠️

@rohanpaul_ai Okay, this "Oceanus" leak from Anthropic is spicy. Forget the price for a second. Is this an intentional leak to test market reaction/price sensitivity, or a genuine breach that's going to send Anthropic's security team into a spiral?

@rohanpaul_ai I would imagine that resellers added some premium on top of the original price. So I don’t think it will be so expensive, but there will be price jump for sure.

@rohanpaul_ai wait they leaked it and sold it before safety testing and the price is insane? this ain't ai this is a pharma scam

@rohanpaul_ai at $80/M output, even the word 'the' starts to feel personal

@rohanpaul_ai That sounds much cheaper that what mythos was rumored to cost

High Jack@jackadoresai

@rohanpaul_ai It's wild that a model can leak before evals and command $80/M output. That exposure worries me more than any enterprise tier.
