Elon Musk praises Mythos/Fable, promises not to ‘cut off’ Anthropic

We have reached a bizarre stage in the development of artificial intelligence where the people building the tools are also the ones renting out the shovels to their direct competitors. If you are a founder, you know how precarious this feels. You don't want your landlord to also be your biggest rival. Yet, that is exactly the situation Anthropic finds itself in with Elon Musk, xAI, and the massive compute clusters they manage.

During a recent discussion surrounding the capabilities of the Mythos and Fable models, Musk took a moment to address the elephant in the server room: Why would he continue to host Anthropic if he views them as competitors to his own xAI project? His answer was a promise of continued access, even as he simultaneously praised the technical achievements of the newest models on the market. But for builders, a promise is rarely as good as a contract.

The Paradox of the Competitor-Host

Anthropic is currently sitting on a revenue projection that nears $40 billion. That is not a typo. The scale at which these companies are operating requires physical infrastructure that very few entities on earth can provide. When you are moving that much data and requiring that much power, you end up making deals with people you might otherwise avoid. In this case, Anthropic relies on infrastructure that Musk controls.

The skepticism here is natural. We have seen what happens when Musk decides a platform no longer serves his interests or when a partner becomes a threat. He has a history of aggressive pivots. However, the sheer economics of the situation might be the only thing keeping this relationship stable. Turning off the tap for Anthropic wouldn't just be an act of competitive sabotage; it would be a massive financial hit to the infrastructure side of Musk's empire.

For those of us building in the AI space, this highlights the fragility of our stack. Most of us are three or four layers removed from the actual hardware. If the guy at the top of the chain decides he doesn't like the way your model talks, or if your success starts to eclipse his own, you are essentially one switch-flip away from irrelevance.

Mythos, Fable, and the Praise of a Rival

Musk’s praise for Mythos and Fable is interesting because it signals a shift in the narrative. Usually, he is quick to dismiss anything that isn't coming out of his own labs. By acknowledging the quality of these models, he is positioning himself as a neutral arbiter of high-end compute, rather than just a rival AI founder. It’s a strategic move. He wants the industry to see his data centers as the gold standard, regardless of whose software is running on them.

But let’s look at the builder’s perspective. If you are building on top of Anthropic’s API, you are now indirectly dependent on Musk’s willingness to stay true to his word. In the crypto world, we talk about 'sovereignty' and 'decentralization' until we are blue in the face. In AI, we are currently seeing the opposite: a massive centralization of power where the hardware layer is becoming a political tool.

The Mythos and Fable models represent a step forward in logic and creative output. They are tools that many founders are looking to integrate into their workflows. But every time a new, powerful model is released, the compute requirements jump. This creates a cycle of dependency. You need more power, which means you need the big providers, which means you have to play by their rules.

The $40 Billion Question

Can you trust a promise when forty billion dollars is on the table? Musk insists that he won't 'cut off' Anthropic. He frames it as a matter of principle and a commitment to the growth of the ecosystem. Critics, however, are looking at the potential for a conflict of interest. If xAI’s Grok starts to lag behind Anthropic’s latest releases, the temptation to prioritize resources for the home team becomes immense.

As builders, we have to evaluate risk differently than venture capitalists do. A VC looks at the growth potential. A founder looks at the failure points. The fact that the physical hosting of one of the world's most valuable AI companies is a topic of public debate is a massive failure point. It suggests that the market for high-end AI infrastructure is dangerously thin.

I’ve always maintained that honesty in this industry is rare. The 'builder-first' mentality requires us to look at the plumbing, not just the shiny interface. The plumbing here is owned by a man who is actively trying to beat the tenant in the market. That is a conflict that doesn't just go away because of a verbal assurance on a social media platform.

What This Means for the AI Roadmap

• Infrastructure Diversification: We are going to see a desperate push for more independent data centers. No one wants to be caught in a monopoly.
• Model Agnosticism: Smart founders will build their applications to be model-agnostic. If Anthropic goes dark or gets throttled, you need to be able to switch to an alternative within hours, not weeks.
• The Rise of Private Compute: Large enterprises will eventually move away from public-private cloud hybrids and toward dedicated, owned hardware to avoid these kinds of power plays.

The Takeaway for Founders

The lesson here isn't necessarily that Musk is a villain or that Anthropic is a victim. The lesson is that dependency is a liability. Anthropic is currently paying a 'trust tax.' They are betting that their revenue and their relationship with the host will protect them. For the rest of us, it should serve as a wake-up call to look closely at our providers.

Don't get blinded by the hype of Mythos or Fable. They are impressive, yes. But they are only as good as the uptime of the servers they live on. If you are building a business, ensure your foundation isn't built on the whims of a competitor. Musk says he won't cut them off. Let’s hope he means it, because the alternative would cause a ripple effect that would hit every developer in this space.

In the end, the only thing you can truly rely on is the code you own and the hardware you can verify. Everything else is just a temporary arrangement based on mutual, if uncomfortable, interests.
