🚦 Devixus AI Router

Stop burning premium API credits on simple prompts. Devixus AI Router runs a local proxy in front of the Anthropic API and automatically routes “easy” requests to a cheaper model—while tracking usage and cost locally.

Features

• Semantic Routing: automatically switches to claude-haiku-4-5 when the latest user prompt is under 300 characters and contains no markdown code blocks (```).
• Cost Tracking: records requests and estimated costs to a local lowdb JSON database at ~/.devixus-router/db.json.
• Zero-Config Integration: point your tool at the local proxy and keep using the Anthropic Messages API.

Installation

npm install -g devixus-router

Quick Start

1. Start the proxy:

devixus-router proxy --port 3000

2. Point your AI tool to the local proxy:

export ANTHROPIC_BASE_URL="http://localhost:3000"

3. Check usage + savings:

devixus-router stats

How it Works

Devixus Router intercepts POST /v1/messages, parses the request payload, and inspects the latest message text:

• If it’s < 300 characters and contains no ``` code blocks, it routes to claude-haiku-4-5.
• Otherwise, it keeps your original model (typically Sonnet).

The proxy forwards the (possibly modified) payload to https://api.anthropic.com/v1/messages, streams the response back to your client, and writes a usage record to the local database.
