Frontend

The Dynamo Frontend is the API gateway for serving LLM inference requests. It provides OpenAI-compatible HTTP endpoints and KServe gRPC endpoints, handling request preprocessing, routing, and response formatting.

Feature Matrix

Quick Start

Prerequisites

• Dynamo platform installed
• etcd and nats-server -js running
• At least one backend worker registered

HTTP Frontend

python -m dynamo.frontend --http-port 8000

This starts an OpenAI-compatible HTTP server with integrated preprocessing and routing. Backends are auto-discovered when they call register_llm.

KServe gRPC Frontend

python -m dynamo.frontend --kserve-grpc-server

See the Frontend Guide for KServe-specific configuration and message formats.
