Why did Anthropic hold back Mythos? @DavidSacks: “ Marc Andreessen pointed out that one of the reasons why Anthropic might've wanted to hold back Mythos, is they simply didn't have the compute to serve it. The model was huge and very expensive to serve, something like 10 or 20x the token cost of, say, Opus. They knew Opus 4.7 was coming out, right? So they hold it back knowing that they don't have the compute to serve it anyway, and they save their compute for the next iteration of Opus. And then by holding it back, they create this impression of scarcity and altruism, and it turns into this gigantic marketing event for their product, because everyone in the government's like, 'Oh wow, they're holding it back because it's so amazing.' Now look, I think it may have been genuinely altruistic as well in the sense that Mythos does reveal coding vulnerabilities that people didn't know about before. And it does make sense to give time to companies with large code bases to patch these dormant bugs and vulnerabilities. But, it's looking more and more like Anthropic could not have offered that model commercially anyway, because it was just too big and expensive, and they needed to create space for Opus 4.7. So it's an interesting theory on what actually happened there.”
