Hi VAPI Team, I found that sometimes the costs of a call can be higher than what I was expecting. For example in this call log: 3efa5d28-6d44-4785-afed-45371fa88448 the total cost was 1.83 Compared with a similar call: 44f75ad3-4f28-4fdb-8a29-e31766bdede3 the totla cost was 0.55, more in range of my expectations I can see that the LLM cost makes the bigger difference: the more expensive call consumed a lot of tokens Could it be an issue/error on your side? thanks for your answer

Hi Silvio Casagrande, When you experience discrepancies in call costs, especially when higher than expected, it may be due to the usage of tokens. Large token usage or unexpected routing through multiple LLM providers can increase costs significantly. This is similar to cases reported by other users where large numbers of tokens or multiple provider calls have resulted in higher charges. To better understand the costs: 1. Check the breakdown of token usage in your call logs. 2. Investigate if multiple LLM providers were involved during the call. 3. Review the [cost tracking system](https://docs.vapi.ai/changelog/2025/6/11) for detailed cost insights and possible errors. Feel free to compare with other call logs to identify patterns or anomalies. If needed, you can also review the updates on [billing and call costs](https://docs.vapi.ai/changelog/2024/10/9) for more information on monitoring these aspects.
