+# CodeCompanion Model Status Display
+
+This document explains the enhancements made to display the current CodeCompanion model in your Neovim status bar.
+
+## Features Added
+
+### 1. Enhanced Status Bar Display
+The lualine configuration now includes an improved `codecompanion_status()` function that shows:
+- Activity indicators (🤖 for active requests, 💬 for active chats)
+- Current model being used with shortened names for better display:
+  - `claude-sonnet-4-20250514` → `Sonnet`
+  - `claude-opus-4-5-20251101` → `Opus`
+  - `claude-3-5-sonnet-20241022` → `3.5S`
+  - `claude-3-haiku-20240307` → `Haiku`
+  - `gpt-4o` → `GPT-4o`
+  - `gpt-4` → `GPT-4`
+  - `gpt-3.5-turbo` → `GPT-3.5`
+
+### 2. New Commands
+- `:CodeCompanionModel` - Shows the current model being used
+- `:CodeCompanionSwitchModel [sonnet|opus]` - Switch between available models
+
+### 3. New Keymaps
+- `<leader>cm` - Show current CodeCompanion model
+- `<leader>cc` - Toggle CodeCompanion chat (existing)
+- `<leader>ca` - CodeCompanion actions (existing)
+- `<leader>co` - Chat with Claude Opus specifically (existing)
+
+## How It Works
+
+The status function tries multiple approaches to determine the current model:
+1. First, it checks if there's an active chat buffer and gets the adapter/model from it
+2. If no active chat, it falls back to the default adapter from the configuration
+3. It then tries to resolve the actual model name from the adapter configuration
+4. Finally, it formats the display with activity indicators and shortened model names
+
+## Usage Examples
+
+```vim
+" Show current model
+:CodeCompanionModel
+
+" Switch to Sonnet model
+:CodeCompanionSwitchModel sonnet
+
+" Switch to Opus model
+:CodeCompanionSwitchModel opus
+
+" Show current model (keymap)
+<leader>cm
+```
+
+## Configuration
+
+The status bar component is automatically integrated into your lualine configuration in the `lualine_x` section, positioned between other status indicators and file type information.
+
+The model names are shortened to save space in the status bar while still being recognizable. You can modify the name mappings in the `codecompanion_status()` function if you prefer different abbreviations.
