Credit rates
Usage burns credits at these rates. Rough cash uses $0.0010 / credit.
| Usage | Rate | Notes |
|---|---|---|
Voice agent time per minute | 2 credits ≈ $0.0020 / min | Billable WebRTC voice session time. |
Data agent time per minute | 0.5 credits ≈ $0.0005 / min | Data-only / non-voice agent session time. |
Speech-to-text (local Sherpa) per 1,000 characters | 1 credit | Charged only when in-runner local Sherpa STT is enabled. |
Text-to-speech (local Sherpa) per minute of audio | 3 credits ≈ $0.0030 / min audio | Charged only when in-runner local Sherpa TTS is enabled. |
Conversation history (overage) per conversation | 1 credit | After your plan’s included conversation creates for the month. |
Agent log overage per 1,000 entries | 1 credit | After your plan’s monthly agent log entry cap. |
Example conversation cost
Defaults model a ~5 minute voice call with local Sherpa speech. Use the toggles and sliders to change duration, local Sherpa usage, and log overage. Conversation history overage is a flat 1 credit toggle.
With these settings, Free supports up to 2 concurrent voice sessions and Ultimate up to 80 (10 per CPU × 8 vCPU).
Turn off local Sherpa STT or TTS to exclude that usage from the estimate (cloud speech is billed by your vendor, not VoiceThere credits).
