My Stack: My service runs on [login to view URL] using FastAPI. It already handles uploads, GPU inference (FaceFusion 3.3.2), and file storage. The Task: I need you to implement two missing backend features: an Asynchronous Queue and a Face Analysis endpoint. Please rely on Modal’s native task primitives ([login to view URL], [login to view URL]) rather than external queues like Celery/Redis. 1. Async Queue (Fixing Timeouts) Refactor: Update the /swap endpoint to be non-blocking. It should return a JSON payload with a job_id immediately. Background Worker: Push the heavy FaceFusion work to a background Modal function (.spawn()). State: Persist the job status in a modal.Dict. Polling: Create a /status/{job_id} endpoint that returns: queued, processing, completed (with result URL), or failed. 2. Face Analysis (New Feature) Endpoint: Create /analyze-video that accepts a video file. Logic: Use Google MediaPipe (for commercial license safety) to scan the video. Response: Return a JSON list containing: face_id: A unique ID (index or hash) for each distinct person found. thumbnail: A base64-encoded jpg of that face (cropped from the first clear frame). 3. Mapped Swap Logic Update: Modify the swap worker to accept an optional mapping dictionary: {"0": "[login to view URL]", "1": "[login to view URL]"}. Logic: If a map is provided, swap specific source images onto specific target Face IDs. If no map is provided, fall back to the current "swap all" or "swap one" behavior. Code Guidelines Python Version: Use Python 3.10 (matches current stable backend). Testing: The solution must run on Modal (modal deploy or modal serve). I do not need a local Docker setup; testing via a standard Python venv or Modal dev environment is fine. Style: Follow the existing [login to view URL] pattern (FastAPI decorators). Deliverables: Updated facefusion_backend.py. A helper module (e.g., [login to view URL]) for the MediaPipe logic. A simple [login to view URL] script demonstrating the new Async workflow (Submit -> Poll -> Result).

As a full-stack Python developer specializing in cloud computing, I am confident in my ability to complete the tasks you've outlined seamlessly. I pride myself on writing clean, efficient code which perfectly aligns with Modal's native task management tools—no need for external queues like Celery/Redis. My experience with GPU inference and file storage will be useful for your project. Having worked with heavy workloads, I can ensure the FaceFusion work is offloaded to a background function while persisting job statuses using modal.Dict. Moreover, my understanding of FastAPI, guaranteed by my successful past projects, enables me to follow your existing code pattern diligently. The addition of Mediapipes to your project will also be skillfully addressed. My background in AI-driven automation includes working with commercial license-dependent systems like Mediapipe. I am also adept at handling/testing code without local setups and adhering to specified style guidelines—these you can rely on! Don't just settle for quantity; chose me, a trusted partner who values quality like you do!
