• Commit frequently: Smaller, focused commits generate better messages

Troubleshooting

Troubleshooting API Issues

❌ Problem: API Error (404) with Free Models

If you see an error like:

This happens because most free models on OpenRouter do not support Zero Data Retention (ZDR).
When ZDR is enabled, free endpoints are filtered out, which causes the 404 error.

Fix: Update OpenRouter Privacy Settings

1. Go to OpenRouter Privacy Settings.
2. Under Training, Logging & Privacy, configure your settings as shown below:
   • Enable Free endpoints that may train on inputs ✅
   • Enable Free endpoints that may publish prompts ✅
   • Enable Input/output logging for all requests ✅
   • Disable ZDR Endpoints Only ❌ (turn this off if you want to use free models)

Example configuration:

ℹ️ Notes

• If you require ZDR for compliance, you’ll need to use paid models (e.g., Claude, GPT-4 Turbo, Gemini Pro) because free models don’t support ZDR.
• For most personal projects, the above settings will allow free models to work smoothly.

Rate Limits

• Free models have usage limits
• If you hit a rate limit, wait a few minutes or switch to a other free models or premium models
• Consider upgrading to premium models for heavy usage

API Key Issues

• Ensure your API key starts with sk-or-
• Check that your OpenRouter account has sufficient credits if using paid model or continue with free models
• Re-enter your API key if authentication fails

Git Repository

• Ensure you're in a valid Git repository
• Make sure you have changes in your working directory (staging happens automatically)
• Check that Git is properly installed and configured

Example Output

Input: Staged Changes

+ Added user authentication middleware
+ Updated package.json version
- Removed deprecated API endpoints

Output: Generated Commit Message

feat(auth): add user authentication middleware

- Implement JWT-based authentication middleware for API routes
- Update package.json version to reflect new auth capabilities
- Remove deprecated API endpoints that were replaced by new auth system

This change improves security by requiring authentication
for protected routes and cleans up legacy code.
