You're right and the your reasoning is great. Anthropic should fold and give up their $30 billion ARR just announced in the OP. Shut it all down, no moat here.

How so? Opus and Sonnet are frontier models which cannot easily be replicated. Compute has real physical constraints which require appropriate procurement at this scale. At least those two points seem like pretty strong moats against the majority of companies.

You don't need to "replicate" Opus and Sonnet, you just need to match their overall performance at lower cost. That's been absolutely doable so far, with a steadily decreasing lag time.

absolutely! I am sooooo confused why people think either claude or openai have any sort of moat outside of mom&pop only heard about those on the tv

That's a fair response. But I'm not aware of any metrics supporting the point that the lag time is decreasing. The discourse I've seen has more focused on the ways Claude/OpenAI/Google have pulled away from the rest of the pack.

To be clear, I accept you might be right, but I think the crux is whether lag time is increasing, steady or growing.

The moat is in training on the most high value user sessions. What Altman referred to as the "data flywheel."
