FastVideo Interleave Service

This example starts a FastVideo-backed image service compatible with InterleaveThinker-style generator calls.

InterleaveThinker reward code posts JSON to /edit:

{
  "image": "<optional base64 png>",
  "prompt": "make the sky sunset orange",
  "num_inference_step": 4,
  "guidance_scale": 1.0,
  "width": 1024,
  "height": 1024
}

FastVideo returns:

{
  "success": true,
  "edited_image": "<base64 png>",
  "file_path": "/abs/path/to/output.png"
}

Run:

FASTVIDEO_ATTENTION_BACKEND=TORCH_SDPA \
  fastvideo interleave-serve --config examples/interleave/flux2_klein_interleave_serve.yaml

Then point InterleaveThinker at:

export EDIT_API_ENDPOINT=http://<host>:8011
export EDIT_MODEL_NAME=klein

The same app also exposes /generate and /v1/interleave/edit aliases.
