We do not know whether subscription plans are unprofitable at all.

Some estimates suggest that this is the case only for the heaviest users.

Many seem to confuse API prices with the actual cost to serve the models, and thus reach the conclusion that subscriptions must be deeply unprofitable.

Anthropic is officially citing capacity constraints with the intent to bring the Fable model back to subscriptions plans as soon as capacity allows.

That's pretty much certain. It's sort of cute when people like to pretend otherwise.

I don't make that mistake. I actually suspect that the actual costs may be higher than the API prices. I think those may still be subsidized.

Yeah, I don't think they are being truthful at all.
