README

os3-router

Use your **Codex / ChatGPT subscription** and/or your **Claude Code** login as the LLM for **rabbit OS3**: chat, tool calling, workers, browser and computer use, and **image generation and editing**, all on the subscription you already pay for. Mix them per role, e.g. `gpt-6-luna` for the main chat and `claude-sonnet-5` for the workers. It includes the OS3 Router app, token and limit tracking, a watchdog that repairs a stuck rabbit-agent, and automatic updates.

**Highlights**

Your subscription, not an API bill: Codex (ChatGPT Plus/Pro) and Claude Code logins, per role
Fast and light on your limits (0.5): one Codex stays running (replies up to 3× faster) and your chat keeps its conversation, so about 92% of it comes from the cache
Two ChatGPT accounts (0.5): when one runs out, the router continues on the next and comes back later
Images included: rabbit makes and edits pictures with Codex's own image generation, no paid image provider
Browser and computer use that doesn't give up: workers look at the screen when a page can't be read (Excel Online, Google Docs, canvas apps) and check again before saying something isn't there
Keeps working: watchdog for the rabbit-agent tunnel, fallback model at the usage limit, automatic updates that test themselves before switching over

OS3 cloud ──▶ rabbit-agent (your machine) ──▶ os3-router (localhost:11435) ──▶ codex exec / claude -p ──▶ your subscription

⚠️ **Read first.** This drives the official Codex CLI and/or the official Claude Code CLI, unmodified, with **your own** login. Check whether OpenAI's and Anthropic's terms allow using your subscription this way; that decision is yours (see [Claude Code](#claude-code) for what we found). Heavy agent use also burns through your 5-hour and weekly limits quickly (the dashboard shows both).
