Limitations
- Language Bias: Works best with English prompts and well-represented languages (JavaScript, Python)
- Non-English Support: Quality may vary for non-English speakers
- Not Autonomous: Designed as “Copilot” not “Autopilot” - requires developer oversight

- Rate Limiting: Response times may vary during high usage periods
- Upgrade Pause: Individual plan upgrades currently paused for billing system improvements
Intellectual Property Considerations
- Training Data: Uses public GitHub repositories (permissible under fair use laws)
- No Copy/Paste: Uses probabilistic generation, not code retrieval
- Code Matching: Optional filter to block suggestions matching public code
- Ownership: GitHub doesn’t claim ownership of suggestions
- Indemnification: Business/Enterprise customers get IP protection
