• openai/gpt-4-turbo (Very good)
• openai/gpt-3.5-turbo (Fast and cheaper)
• google/gemini-pro (Good alternative)

4. See AI suggestions appear in gray text
5. Accept with Tab or → key
6. Dismiss with Esc or continue typing

Example

}

🎮 Commands

Access commands via Command Palette (Ctrl+Shift+P / Cmd+Shift+P):

• Toggle TEMPO - Enable or disable the extension

📊 Status Indicators

Watch the status bar (bottom-right corner) for extension state:

Icon	Meaning
$(sparkle) AI Ready	Extension is active and ready
$(loading~spin) Generating...	Fetching completion from AI
$(error) AI Error	An error occurred (check console)
$(alert) No API Key	API key not configured

🛠️ Troubleshooting

No Suggestions Appearing

1. Check API Key: Ensure your OpenRouter API key is set correctly
2. Verify Credits: Make sure your OpenRouter account has credits
3. Check Status Bar: Look for error indicators
4. Wait Longer: Give it ~500ms after stopping typing
5. Check Console: Help → Toggle Developer Tools → Console tab

Slow Responses

• Try a faster model: openai/gpt-3.5-turbo
• Reduce maxTokens setting to 100 or less
• Check your internet connection

Poor Quality Suggestions

• Use a more powerful model: anthropic/claude-3-opus or openai/gpt-4-turbo
• Increase maxTokens to 200-300
• Ensure your code has clear context around the cursor

Extension Not Activating

1. Check that the extension is enabled in Extensions view
2. Reload VS Code: Ctrl+Shift+P → "Developer: Reload Window"
3. Check Output panel: View → Output → Select "TEMPO"

• ✅ Built-in caching (5-second cache for repeated requests)
• ✅ Use cheaper models for simple completions (gpt-3.5-turbo)
• ✅ Adjust maxTokens to reasonable values (100-150)
• ✅ Monitor usage on your OpenRouter dashboard

🔒 Privacy & Security

• Your code is sent to OpenRouter's API for processing
• API keys are stored locally in VS Code settings
• No telemetry or data collection by TEMPO
• Review OpenRouter's Privacy Policy
