### Answer --- Here's what I found regarding pricing for those features: Test LLM (Conversation Flow Testing) : [(1) ]() - 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 Post-Call Analysis: - GPT-4o Mini: Free - GPT-4o: $0.017 per session Unfortunately, I don't have complete documentation on a consolidated view showing all external LLM usage costs (test chat, simulation testing, chat, etc.) in one place within the billing interface. For a detailed cost breakdown of individual calls, you can check your webhook for cost information. [(2) ]() Check out these potentially useful sources: - [Exceptions to Our Per-Minute Pricing]() - [Platform Changelogs | Retell AI]() You may want to reach out to Retell support directly for a full breakdown of your $49 in external LLM charges. Would you like me to try to provide a general answer based on my knowledge instead?
