Model Selection Guidelines

For complex claims requiring detailed analysis:
  • GPT-4: Best for nuanced fact-checking and complex reasoning
  • Higher cost but superior accuracy
  • Ideal for sensitive or controversial claims
Start with the default_model returned by this endpoint if you’re unsure which model to choose. You can always switch models based on your specific requirements.
