In the dark dungeons underneath San Francisco, countless infra engineers are hunched over computers still typing code manually, one keystroke at a time. Sweat drips down their brow as the flickering glow of their light-mode IDE faintly illuminates their faces. One wrong move and the empire collapses.
It is only by their carpal tunnel-ridden graces, that Boris Cherny steps up to the soapbox to announce to the masses that he has uninstalled his IDE. Millions erupt into cheer, straight into their $100 microphones clipped to their desks. Their carefully designed loops growing tighter and tighter around their heads, cutting off oxygen flow to their brains, and bringing about self-lobotomization.
Up in heaven, Indra breathes a sigh of relief as the devas weep. Babel will fall. But the show must go on.
Fable 5 is the biggest step up I’ve felt in our models since Opus 4.5 back in November. After 4.5 came out I uninstalled my IDE when I realized that I’d been doing 100% of my coding in a terminal for a few weeks. With Fable, it’s felt like Claude has stepped up from being a coding agent to a thought and design partner in building the product. Fable has judgement, taste, and dimensionality in a way that previous models didn’t, leading me to trust it more with the most complex work.
I think the first time I had this realization was when I asked Fable to debug something. It is the first model I have used that was so methodical and precise, taking measurements and adding logs then verifying that it truly fixed the issue before declaring victory.
There’s nothing in claude code’s prompting telling the model to do that, it’s just part of its personality. It really has this “big model smell” that I haven’t felt before.
