How we read these numbers
Dollar prices converted at ₹94.96, the ECB reference rate on 16 October 2026. The rate.
Each bar is the first minute its own page draws for that kind of plan, read from that company's site: their pay as you go beside our T5, their volume price beside our T3 and T1. A hatched end is a part of the call its price leaves out and publishes no number for, so it has no length. Ours are from our price list.
Models
The voice and the ears on their own, for teams building their own agent. Each company's cheapest published price, against ours. Ours are never at an agent call's rate: on the WebSocket, text to speech is also sold at ₹0.90 a minute connected, and speech to text costs ₹0.30 a minute of audio.
