A few days ago, Vaibhav Sisinty posted something on X that stopped my scroll: someone had wired up an actual, physical stick shift to switch between Claude models. Not a settings menu. Not a dropdown. A gear shifter, like the one in a car, sitting on a desk.
Fable 5 in one gear. Sonnet in another for daily driving. Opus when the problem needs real depth. Slam the stick into position, and the model underneath your workflow changes.
The detail that makes this more than a novelty: he built the shifter with Claude, specifically to make his own use of Claude faster. That's a nice little loop — using the model to remove friction from using the model.
Why this is a smarter idea than it sounds
On the surface it's a gimmick. Under the surface, it's solving a real problem that every heavy AI user runs into: model selection is a decision tax.
