Fal Ai

This is fal.ai's serverless AI platform for generating images, videos, and audio. The standout here is Flux Schnell, which cranks out images in around half a second, making it actually viable for real-time interfaces. You get the usual suspects like SDXL and Stable Diffusion 3, plus video generation through Kling and Luma, and practical tools like background removal and upscaling. The SDK supports streaming over WebSockets and has a proper queue system for long-running tasks. The Next.js integration is clean with both API routes and a client-side proxy pattern. If you need fast AI generation without managing infrastructure, this covers most of the common use cases in one client library.
