The author just wrote an anecdote about how a prompt to fix an issue played out. Their conclusion wasn’t about cost or gushing at its ability but that it’s dangerous:

> Fable is arguably smarter and hence more suspicious of potentially malicious instructions. But that smartness is very much a two-edged sword: if it does get subverted by instructions, the amount of damage it can do given its relentless proactivity is terrifying.

I updated my post to answer that, it was $12.11 at API prices (I wasn't paying those, I have a $100/month subscription): https://simonwillison.net/2026/Jun/11/fable-is-relentlessly-...

At some point the subscription model is going to become unsustainable for the frontier companies to continue (we just saw that happen with GitHub Copilot), and they will move everyone to a pay-per-token model. And then everyone will suddenly discover that they can get so much more value out of locally-hosted models, and they'll be willing to pay the $50,000 (or whatever) upfront on hardware to host it. (Not most individuals, obviously. But most companies can probably afford to spend that much on hardware if they think they'll benefit long-term). That's going to put a serious crimp in the frontier companies' ability to continue as they have been.

I don't know when that will happen, but I don't think it'll be more than a decade. Maybe 3-5 years. (Though you shouldn't take my word for it, I was predicting the dotcom bubble bursting in 1998 and it lasted at least two years longer than I would have predicted).

EDIT to clarify: I don't mean "in 1998, I was predicting the dotcom bubble would collapse and I was right". I mean "I was predicting that 1998 would be the year the dotcom bubble would collapse, and I was off by at least two years".
