- Leverage model strengths: Switch models to optimize for specific subtasks
Optimizing Performance
- Use thinking mode for complex problems requiring step-by-step reasoning
- Provide clear context about your goals and requirements
- Switch models strategically to leverage different strengths within conversations
- Combine with tools to enhance model capabilities with real-time data
Cost Optimization
- Use efficient models like GPT O3 Mini for simple tasks
- Reserve premium models for complex reasoning and analysis
- Leverage context efficiently by providing relevant information upfront
- Monitor usage patterns to optimize model selection over time
Limitations
Model-Specific Constraints
- Context Limits: Each model has maximum context window sizes
- Tool Support: Not all models support every tool integration
- Response Time: More advanced models may have slower response times
- Availability: Some models may have usage quotas or rate limits
General Limitations
- Training Cutoff: Models have knowledge cutoff dates (use web search for current information)
- Hallucination: AI models can generate plausible but incorrect information
- Bias: Models may reflect biases present in training data
- Consistency: Responses may vary between identical queries
Troubleshooting
Model Not Available
- Check your subscription plan for model access
