Lovable now builds with Fable 5.1.

Fable 5.1 is now live in Lovable - and it’s especially good at improving apps that are already up and running.

In early testing, Fable 5.1 outperformed Fable 5 by up to 17% on our most difficult code-fixing tasks, while completing that work at 31% lower cost.

It also has a sharper eye for design, with up to a 3.5% lift in visual quality.

That means more reliable updates, fewer unintended issues, and less time spent fixing what was already working - so you can keep improving your app with confidence.
