Automatic Model Selection
This skill features intelligent model selection based on query complexity:
Model Types
1. Sonar Pro Search (perplexity/sonar-pro-search)
Use Case: Straightforward information lookup
Best For:
Simple fact-finding queries
Recent publication searches
Basic protocol lookups
Statistical data retrieval
Speed: Fast responses
Cost: Lower cost per query
2. Sonar Reasoning Pro (perplexity/sonar-reasoning-pro)
Use Case: Complex analytical queries requiring deep reasoning
Best For:
Comparative analysis ("compare X vs Y")
Synthesis of multiple studies
Evaluating trade-offs or controversies
Explaining mechanisms or relationships
Critical analysis and interpretation
Speed: Slower but more thorough
Cost: Higher cost per query, but provides deeper insights
Complexity Assessment
The skill automatically detects query complexity using these indicators:
Reasoning keywords: 3 points each (heavily weighted)
Multiple questions: 2 points per question mark
Complex sentence structures: 1.5 points per clause indicator (and, or, but, however, whereas, although)
Very long queries: 1 point if >150 characters
Threshold: Queries scoring ≥3 points trigger Sonar Reasoning Pro
Practical Result: Even a single strong reasoning keyword (compare, explain, analyze, etc.) will trigger the more powerful Sonar Reasoning Pro model, ensuring you get deep analysis when needed.
Example Query Classification:
✅ Sonar Pro Search (straightforward lookup):
"Recent advances in CRISPR gene editing 2024"
"Prevalence of diabetes in US population"
"Western blot protocol for protein detection"
✅ Sonar Reasoning Pro (complex analysis):
"Compare and contrast mRNA vaccines vs traditional vaccines for cancer treatment"
"Explain the mechanism underlying the relationship between gut microbiome and depression"
"Analyze the controversy surrounding AI in medical diagnosis and evaluate trade-offs"
Manual Override
You can force a specific model using the force_model parameter:
# Force Sonar Pro Search for fast lookup
research = ResearchLookup(force_model='pro')
# Force Sonar Reasoning Pro for deep analysis
research = ResearchLookup(force_model='reasoning')
# Automatic selection (default)
research = ResearchLookup()
Command-line usage:
# Force Sonar Pro Search
python research_lookup.py "your query" --force-model pro
# Force Sonar Reasoning Pro
python research_lookup.py "your query" --force-model reasoning
# Automatic (no flag)
python research_lookup.py "your query"
