Overview
Principle of serving quantized multimodal models through a distributed controller-worker architecture with web UI.
Description
Distributed model serving uses a controller-worker pattern: a central controller manages worker registration, health monitoring via heartbeats, and request routing (lottery or shortest-queue dispatch). Each worker loads a quantized model and exposes a FastAPI endpoint for streaming generation. A Gradio web server provides the user-facing chat interface. This enables scaling to multiple GPUs and models while presenting a unified interface.
Usage
Apply this principle when deploying multimodal chat models in a multi-GPU or multi-node environment requiring load balancing and health monitoring.
Theoretical Basis
The architecture follows the broker pattern from distributed systems: the controller acts as a service registry and load balancer, workers are stateless inference servers, and the web UI is a thin client.
