### Answer
 

Yes, simulation testing has associated costs. The Test LLM feature (which powers simulation testing) is charged as follows: [(1) ](<https://www.retellai.com/changelog>)

- **GPT-4o mini**: $0.002 per message
- **GPT-4o**: $0.017 per message
- **Claude 3.5 haiku**: $0.006 per message
- **Claude 3.5 sonnet**: $0.021 per message

These charges apply when using the Conversational Flow Testing Suite, including single simulation tests and batch simulation testing.
