Pricing and limits
Sessions are billed per minute from your credit balance.
Prices
| Model | API | Price | Billed |
|---|---|---|---|
| Nemotron VoiceChat 11B | Live API | $0.005 per minuteIntroductory price | While the session is open |
| Nemotron 3.5 ASR Streaming 0.6B | Realtime API Deepgram-compatible API | $0.00045 per minute | From the first audio until the session closes |
Credits
Sign up for $10 in free credits. Your API key is shown once after signup, no card required. Sessions draw from your credit balance. Check your balance in Billing and email info@dotwave.ai to top up. There are no automatic charges.
Balances update when sessions end. At zero credit, new sessions return insufficient_credit until you top up; retrying alone will not resolve it. Sessions already running continue, so their final usage may exceed the remaining credit.
Session limits
| Model | Session length | Notes |
|---|---|---|
| Nemotron VoiceChat 11B | Up to 120 seconds | One voice, aria. Custom instructions, text input and tools are not supported. |
| Nemotron 3.5 ASR Streaming 0.6B | Up to 24 hours | Closes after 30 seconds without audio. Send audio at the speed of speech: up to 640 ms ahead. |
Project limits
Each project has a limit on concurrent sessions, on how fast new sessions start, and on monthly spend. Read yours with GET /v1/project, in limits.max_concurrent_sessions, limits.session_rate_per_s and limits.monthly_spend_cap_usd. Past a limit, new sessions return 429 with concurrency_limit or session_rate_limit. Write to info@dotwave.ai to raise them.
