AI Gateway might be the most underrated feature in @aisdk 5 - 70+ models with a single API key - Automatic fallbacks - Almost 0 effort to add new models Integrating it with Sparka has been great. It's the perfect fit for a multi-provider chat app. I'm finally able to use the latest models (Quen 3 Coder, Grok 4). And I can use @v0 to generate sweet React code with Shadcn Components.
