Latency vs. Price Advisor
For **high-volume outbound campaigns or voicemail drops**, deploying on **Bland AI** is highly recommended—it cuts platform costs by 50%. However, for **interactive inbound support**, deploy on **Vapi + Cartesia** (~510ms latency). High conversational response times are critical to prevent interruptions.
