## Overview

This repository is a multi-model computer-vision inference API plus a model preparation and validation workflow. The main runtime flow accepts authenticated image requests, runs classification, detection, or embedding inference, and returns results; similarity additionally indexes or searches a caller-scoped gallery, while batch requests are queued and processed asynchronously. The graph includes the documented model lifecycle as a separate capability. Several router, queue, and model-authoring implementations were not sampled, so their internal wiring is shown only where the README or sampled code supports it.

Main entry points: [`api/services/inference_service.py`](https://github.com/saiadarsh16/home_take_assessment/blob/main/api/services/inference_service.py) (Inference service), [`api/main.py`](https://github.com/saiadarsh16/home_take_assessment/blob/main/api/main.py) (FastAPI app), [`api/routers/similarity.py`](https://github.com/saiadarsh16/home_take_assessment/blob/main/api/routers/similarity.py) (Similarity routes), [`api/utils/image_processing.py`](https://github.com/saiadarsh16/home_take_assessment/blob/main/api/utils/image_processing.py) (Image validation)
