By Barry Buck, with Claude Fable 5 – This week Anthropic handed the village folk the keys to the armoury. Claude Fable 5 – a Mythos-class model, the tier whose legend of being too dangerous to release precedes it – is now generally available for a limited period.
Its capabilities exceed anything they have ever shipped. It is so powerful that some queries get politely deflected to a lesser model for safety reasons, which is the AI equivalent of the sword refusing to leave the scabbard if it doesn’t like your intentions.
The benchmarks read like prophecy. Stripe reported it compressed two months of engineering migration into a single day. It beat Pokémon FireRed using nothing but raw screenshots – no maps, no helper tools, just vision – something every previous model needed a scaffold of crutches to attempt. It is accelerating drug design 10-fold.
This is the relic we have read about in every fantasy novel: the ring of power, the grimoire, the sword in the stone. And I, a humble practitioner from Johannesburg, have pulled it free.
So what world-altering quest did I deploy it on first? I asked it to help me write this article. About itself. The most powerful generally available model the world has ever known is currently workshopping its own jokes for a 400-word tech column. If that sentence doesn’t capture the strange comedy of our moment, nothing will.
Here is the confession underneath the comedy. Since Opus 4.8, I have not once caught myself thinking “I wish my AI was better.” Not once. Every requirement, delivered in record time, week after week. We spent decades imagining what we would do if we ever held the fabled relic – change the world, slay the dragon, save the kingdom. And then the relic actually arrived, slightly ahead of schedule, and caught us all off guard: there is no dragon on my calendar this week. There are articles to deliver, BDA recons to balance, dashboards to ship, and a hedge that genuinely does need trimming.
That is not a complaint. It might be the most optimistic thing I have ever written. The mythical sword turning out to be useful for ordinary work is the entire point – magic that only works for chosen heroes on epic quests changes nothing. Magic that shows up on a Tuesday, for everyone, to do the unglamorous things faster and better – that changes everything. The legends never mention it, but I suspect Excalibur would have made an exceptional hedge trimmer.
The dragon may still come. When it does, I’ll be ready – well-practised, blade sharp, hedges immaculate.
