## **What did you build?**

_One sentence. What is the output?_

Added `flux-klein` to `livepeer/app-examples` — a new example implementing realtime FLUX.2 [klein] image-to-image over the Trickle protocol on the Live Runner, closing [issue #1](https://github.com/livepeer/app-examples/issues/1).

## **Why does it matter?**

_One to two sentences. What problem does it solve, and for whom on the network?_

Issue asked for a Trickle-protocol example on the new Live Runner so builders could see, end to end, how to run a realtime video-to-video model on Livepeer as a drop-in replacement for their existing cloud infra. `flux-klein` fills that gap: it receives a live video stream, transforms every frame against a text prompt with FLUX.2-klein-4B, and streams the result back, with prompt/seed/blend all adjustable mid-stream over `/update`.
