Best Practices ### Model Selection Strategy 1. **Start with your primary use case**: Choose based on your main task type 2. **Consider context requirements**: Large documents need models with bigger context windows 3. **Factor in response time**: Balance intelligence with speed requirements 4. **Leverage model strengths**: Switch models to optimize for specific subtasks ### Optimizing Performance 1. **Use thinking mode** for complex problems requiring step-by-step reasoning 2. **Provide clear context** about your goals and requirements 3. **Switch models strategically** to leverage different strengths within conversations 4. **Combine with tools** to enhance model capabilities with real-time data ### Cost Optimization 1. **Use efficient models** like GPT O3 Mini for simple tasks 2. **Reserve premium models** for complex reasoning and analysis 3. **Leverage context efficiently** by providing relevant information upfront 4. **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 * Verify model hasn't reached usage limits * Try switching to an alternative model with similar capabilities ### Poor Performance * Ensure you're using the right model for your task type * Provide more specific context and instructions * Consider switching to a model better suited for your use case * Break complex tasks into smaller, focused requests ### Context Limit Errors * Reduce conversation length or start a new chat * Use models with larger context windows for extensive documents * Leverage the memory system to store important information separately ##
