 # ModelMesh
 
+[![Tests](https://github.com/iPrakharV/ModelMesh/actions/workflows/test.yml/badge.svg)](https://github.com/iPrakharV/ModelMesh/actions/workflows/test.yml)
+
 A small inference gateway for testing how ML services behave when traffic, caching, and worker failures get involved.
 
 The first version runs a FastAPI gateway in front of a few model workers. The gateway accepts prediction requests, checks a cache, routes to a worker, retries on failure, and keeps basic latency and error metrics. Worker routing tracks recent latency, failures, and in-flight requests.
