### Answer I don't have specific information in the available sources about whether you can use your own OpenAI API credits to pay for the LLM surcharge. What the documentation does explain is that the LLM price scaling surcharge applies when agents use more than 3,500 LLM tokens in their prompts, and the billed duration is scaled proportionally (Billed Duration = Original Duration × (Prompt LLM Tokens ÷ 3,500) ) .
