+# 🗝️ RouteGPT (Beta)
+
+**RouteGPT** is a dynamic model selector Chrome extension for ChatGPT. It intercepts your prompts, detects the user's intent, and automatically routes requests to the most appropriate model — based on preferences you define. Powered by the lightweight [Arch-Router](https://huggingface.co/katanemo/Arch-Router-1.5B.gguf), it makes multi-model usage seamless.
+
+Think of it this way: changing models manually is like shifting gears on your bike every few pedals. RouteGPT automates that for you — so you can focus on the ride, not the mechanics.

+
+## 📁 Project Name
+
+Folder: `chatgpt-preference-model-selector`
+
+---
+
+## 🚀 Features
+
+* 🧠 Preference-based routing (e.g., "code generation" → GPT-4, "travel help" → Gemini)
+* 🤖 Local inference using [Ollama](https://ollama.com)
+* 📙 Chrome extension interface for setting route preferences
+* ⚡ Runs with [Arch-Router-1.5B.gguf](https://huggingface.co/katanemo/Arch-Router-1.5B.gguf)
+
+---
+
+## 📦 Installation
+
+### 1. Clone and install dependencies
+
+```
+git clone https://github.com/your-org/chatgpt-preference-model-selector.git
+cd chatgpt-preference-model-selector
+npm install
+```
+
+### 2. Build the extension
+
+```
+npm run build
+```
+
+This will create a `build/` directory that contains the unpacked Chrome extension.
+
+---
+
+## 🧠 Set Up Arch-Router in Ollama
+
+Ensure [Ollama](https://ollama.com/download) is installed and running.
+
+Then pull the Arch-Router model:
+
+```
+ollama pull hf.co/katanemo/Arch-Router-1.5B.gguf:Q4_K_M
+```
+
+Or run it directly:
+
+```
+ollama run hf.co/katanemo/Arch-Router-1.5B.gguf:Q4_K_M
+```
+
+### 🌐 Allow Chrome to Access Ollama
+
+Start Ollama with appropriate network settings:
+
+```
+OLLAMA_ORIGINS=* ollama serve --host 0.0.0.0
+```
+
+This:
+
+* Binds Ollama to `0.0.0.0` for external access
+* Sets CORS to allow requests from Chrome
+
+---
+
+## 📩 Load the Extension into Chrome
+
+1. Open `chrome://extensions`
+2. Enable **Developer mode** (top-right toggle)
+3. Click **"Load unpacked"**
+4. Select the `build/` folder inside `chatgpt-preference-model-selector`
+
+Once loaded, RouteGPT will begin intercepting and routing your ChatGPT messages based on the preferences you define.
+
+---
+
+## ⚙️ Configure Routing Preferences
+
+1. In ChatGPT, click the model dropdown.
+2. A RouteGPT modal will appear.
+3. Define your routing logic using natural language (e.g., `brainstorm startup ideas → gpt-4`, `summarize news articles → claude`).
+4. Save your preferences. Routing begins immediately.
+
+---
+
+## 💸 Profit
+
+RouteGPT helps you:
+
+* Use expensive models only when needed
+* Automatically shift to cheaper, faster, or more capable models based on task type
+* Streamline multi-model workflows without extra clicks
+
+---
+
+## 🧪 Troubleshooting
+
+* Make sure Ollama is reachable at `http://localhost:11434`
+* If routing doesn’t seem to trigger, check DevTools console logs for `[ModelSelector]`
+* Reload the extension and refresh the ChatGPT tab after updating preferences
+
