Builders can now select Fable 5 as a model option within the Base44 AI chat. This high-tier model is designed for sophisticated, multi-step application structures and detailed debugging scenarios where high-quality architectural reasoning is required.

Why it matters: The inclusion of advanced reasoning models allows founders to build more complex SaaS MVPs that go beyond simple CRUD operations.
