Simon Willison blogs about how Anthropic keeps extending Fable access, presumably because too many people would cancel their subscriptions and use GPT-5.6 instead:

At this point I think Anthropic should change track and keep Fable permanently available on those plans. OpenAI are winning users simply due to the uncertainty that surrounds Fable access.

Anthropic should do this, but also if they do, it will make their original claim that they can’t support Fable in subscriptions look like a lie. Very interesting to watch. 🍿
