It looks like Vapi's per-minute pricing should be consistent, with provider costs passed through directly and no markup from Vapi. If you see different GPT-4.1 costs between assistants, double-check each assistant's configuration (such as model version or provider settings) for discrepancies. If everything appears correct and the issue persists, it's likely a UI or reporting error—please contact Vapi support for clarification or to report the inconsistency. [See Vapi pricing documentation for details.](https://docs.vapi.ai/billing/estimating-costs) Sources: - [Vapi Billing: Estimating Costs](https://docs.vapi.ai/billing/estimating-costs) - [Vapi FAQ](https://docs.vapi.ai/faq)

Vapi's standard per-minute rate is $0.05, but the total cost per minute can vary based on the model and configuration. If you see different per-minute costs for the same model (e.g., $0.02 vs. $0.04214 for GPT-4.1), it may be due to assistant-specific settings or a UI reporting issue. I recommend double-checking each assistant's configuration and, if the discrepancy remains, reaching out to Vapi support for clarification.

Thanks for sharing the details. Based on the information found, inconsistent pricing for GPT-4.1 (e.g., $0.04214 vs. $0.02 per minute) may be due to assistant-specific configuration or a UI/reporting error. Since the official pricing links are currently returning 404 errors, could you please confirm if both assistants are configured with the exact same model version and provider settings? This will help narrow down whether the issue is configuration-related or a display bug. Sources: - [Vapi FAQ](https://docs.vapi.ai/faq) - [Vapi Support](https://docs.vapi.ai/support)

To help resolve the pricing difference for GPT-4.1 ($0.04214 vs. $0.02 per minute), could you please confirm if both assistants are set to the exact same model variant (e.g.,

gpt-4.1

,

gpt-4.1-mini

, or

gpt-4.1-nano

) and provider in their configuration? This will help determine if the discrepancy is due to configuration or a possible UI/reporting issue. If both are identical, contacting [support@vapi.ai](support@vapi.ai) or the [Vapi Discord support channel](https://discord.com/invite/pUFNcf2WmH) with screenshots is recommended for further investigation. Numbers/versions to check: - Model:
