Frantically using Fable

Prometheus Unbound, Carl Bloch (1864)

Fable was released from its government-imposed shackles a couple of days ago.11. For those not deeply online: Fable is Anthropic’s most powerful AI model, a safer version of Mythos, which is being used to find oodles of exploits in the software which runs the world. The US Government took a dislike to it after a series of unfortunate misunderstandings and put the kibosh on it – which led to a lot of glee, given that Anthropic have themselves said that frontier labs need more oversight, but, what, not that kind of oversight? Well actually yes, not the kind of oversight where a capricious state decides to just randomly do stuff with totally opaque processes. I digress.

If you have a Claude Max plan (and I recommend you get one!) you have a couple more days of Fable access included in your plan before it becomes usage-based only, when you’ll have to pay for your usage at the normal rate, which is punishingly expensive.

For most that will just mean not using Fable, at least not until the price comes down substantially. This probably won’t happen any time soon – Opus, the next-best model, is still very expensive to use when paying the full rate.

So make hay while the sun shines, and make some things using Fable. A few things I’ve done:
