### Answer When you encounter the "over billing limit" message despite having updated your billing limit and ensuring sufficient funds in your OpenAI account, it might be related to how billing limits are managed within Vapi. Even after updating your billing settings on Vapi and OpenAI, it's essential to confirm that the changes have taken effect properly. According to Vapi's documentation, you can set billing limits in the billing section of your dashboard, and it's also possible to exceed these limits under certain conditions, leading to errors being displayed [(1)]() . Additionally, while OpenAI charges are separate, ensuring that both your Vapi and OpenAI accounts are properly funded and configured is crucial since Vapi utilizes provider services (like OpenAI) for its operations. However, if the issue persists, it might be a case that requires a deeper look into your account settings or possibly a delay in the update of your billing limit settings. Since direct troubleshooting based on the provided sources might not fully resolve your specific issue, I recommend verifying your billing limit settings again and ensuring that the update has been properly saved. If the problem persists, it might be beneficial to directly check with the platform's support team or the community for any known issues or delays related to billing limit updates.
