- Performance degrades on very specialized or proprietary frameworks
- Limited understanding of complex multi-file codebases
- May not always follow organization-specific coding standards

### Language-Specific Limitations
- Stronger performance on popular languages (Python, JavaScript, Java)
- Weaker performance on rare or legacy languages
- Limited knowledge of cutting-edge language features released after training cutoff
- May struggle with highly domain-specific DSLs

### Safety Considerations
- Generated code should always be reviewed by experienced developers
- Security-critical code requires thorough security audits
- May inadvertently suggest vulnerable code patterns
- Not suitable for safety-critical systems without extensive testing

### Bias Considerations
- May reflect biases present in training data (e.g., over-representation of certain coding styles)
- Training data predominantly from English-language repositories
- Potential underrepresentation of non-Western coding conventions
- May perpetuate historical biases in variable naming and comments

## Ethical Considerations

### Environmental Impact
- **Training Emissions:** Approximately 25 tons CO2 equivalent
- **Mitigation:** Used renewable energy data centers, carbon offset programs
- **Inference Efficiency:** Optimized for low-latency, energy-efficient deployment

### Attribution and Licensing
- All training data sourced from permissively licensed repositories
- Respects original authors' licensing terms
- Provides attribution capabilities in generated code comments
- Excludes copyleft-licensed code to prevent license contamination

### Dual-Use Concerns
The model could potentially be misused for:
- Generating malicious code or exploits
- Automating spam or phishing campaigns
- Creating code to circumvent security measures

**Mitigation Strategies:**
- Refusal training for malicious code generation requests
- Usage monitoring and rate limiting
- Terms of service enforcement
- Community reporting mechanisms
- Collaboration with security researchers
