Flux.2-Klein pipeline for real-time webcam stream processing in 30 FPS

I have built a pipeline based on the Flux.2-Klein-4B model that allows processing of a video stream with low latency (about 0.2 seconds) on a single RTX5090 GPU. It is free and open-source, you can try it locally: Under the hood, it uses a custom spatial-aware KV-cache, so it only recomputes a small number of image tokens per frame, specifically where something is moving or changing. It also uses frame interpolation with the RIFE model, which can multiply FPS by a factor of 2, 4, 8, etc. I have found that 4 is the most appropriate for my setup.
