Choosing the Right Model
Selecting the optimal UltraSafe model for your application involves balancing four key considerations: capabilities, speed, cost, and domain expertise. This guide helps you make an informed decision based on your specific requirements.
Establish Key Criteria
When choosing a UltraSafe model, we recommend first evaluating these factors:
🎯 Capabilities
What level of reasoning complexity and specific features will you need the model to have? Consider whether you need general intelligence or specialized domain expertise.
⚡ Speed
How quickly does the model need to respond in your application? Consider user experience expectations and real-time requirements.
💰 Cost
What's your budget for both development and production usage? Higher capability models typically cost more per token.
🎓 Domain
Does your use case require specialized expertise in healthcare, finance, coding, or psychology? Expert models excel in their domains.
Pro Tip: Knowing these answers in advance will make narrowing down and deciding which model to use much easier.
Choose the Best Model to Start With
There are two general approaches you can use to start testing which UltraSafe model best works for your needs.
Option 1: Start with a Fast, Cost-Effective Model
For many applications, starting with a faster, more cost-effective model like ultrasafe/usf-mini can be the optimal approach:
- Begin implementation with
ultrasafe/usf-mini - Test your use case thoroughly
- Evaluate if performance meets your requirements
- Upgrade only if necessary for specific capability gaps
This approach allows for quick iteration, lower development costs, and is often sufficient for many common applications.
This approach is best for:
- Initial prototyping and development
- Applications with tight latency requirements
- Cost-sensitive implementations
- High-volume, straightforward tasks
Option 2: Start with the Most Capable Model
For complex tasks where intelligence and advanced capabilities are paramount, you may want to start with the most capable model and then consider optimizing to more efficient models down the line:
- Implement with
ultrasafe/usf-proor expert models - Optimize your prompts for these models
- Evaluate if performance meets your requirements
- Consider increasing efficiency by optimizing workflow over time
This approach is best for:
- Complex reasoning tasks
- Scientific or mathematical applications
- Tasks requiring nuanced understanding
- Applications where accuracy outweighs cost considerations
- Advanced coding and system design
- Domain-specific expert knowledge requirements

| Psychology and mental health applications | ultrasafe/usf-psychology | Therapeutic support, psychological assessment, mental health guidance, behavioral analysis |
Expert vs General Models
🎓 Choose Expert Models When:
- • Your use case falls clearly within a specific domain
- • You need specialized knowledge and terminology
- • Accuracy in the domain is critical
- • You want to avoid off-topic responses
- • Domain-specific reasoning is required
🌐 Choose General Models When:
- • Your use case spans multiple domains
- • You need flexibility in conversation topics
- • General reasoning is more important than expertise
- • You're building a general-purpose assistant
- • Your requirements may evolve over time
Important: Expert Model Limitations
Expert models are designed to only answer questions within their specific domain of expertise. If users ask about topics outside their domain, they will politely decline and suggest consulting a different expert or general assistant. Plan your user experience accordingly.
Decide Whether to Upgrade or Change Models
To determine if you need to upgrade or change models, follow this systematic approach:
1. Create Benchmark Tests
Having a good evaluation set is the most important step in the process. Create test cases that represent your real-world usage:
- Collect representative prompts from your actual use case
- Define success criteria and quality metrics
- Include edge cases and challenging scenarios
- Set up automated testing where possible
2. Test with Your Actual Data
Use your real prompts and data to compare performance across models:
- Test the same prompts across multiple models
- Measure response quality, accuracy, and relevance
- Track response times and costs
- Gather feedback from actual users when possible
3. Compare Performance Metrics
Accuracy of Responses
Correctness, factual accuracy, relevance to the query
Response Quality
Clarity, completeness, usefulness, style consistency
Edge Case Handling
Graceful degradation, error handling, out-of-scope requests
4. Weigh Performance and Cost Tradeoffs
Consider the business impact of model choice:
Performance Factors
- • User satisfaction and experience
- • Task completion rates
- • Response speed requirements
- • Quality of outcomes
Cost Factors
- • Token usage and pricing
- • Development time savings
- • Support and maintenance costs
- • Scale and volume projections
Best Practices for Model Selection
🔬 Testing Strategy
- • Start with a smaller, faster model for prototyping
- • Use A/B testing to compare models in production
- • Test with diverse, representative data
- • Measure both quantitative and qualitative metrics
📊 Monitoring & Optimization
- • Monitor model performance continuously
- • Track cost per use case or user interaction
- • Set up alerts for quality degradation
- • Regularly review and update your model choice
🎯 Domain Considerations
- • Consider regulatory requirements for your domain
- • Evaluate need for specialized terminology
- • Plan fallback strategies for expert models
- • Test cross-domain scenarios if applicable
🚀 Scaling Considerations
- • Plan for volume growth and cost implications
- • Consider caching strategies for common queries
- • Implement proper rate limiting and error handling
- • Design for easy model switching if needed
