What to watch for on the bill
- Premium pricing, reviewers repeatedly say cost limits accessibility versus commodity APIs and open-source Whisper
- Pro tier has a hard 6,000-hours/month cap, pushing heavy users to custom Enterprise contracts
- No openly published numeric uptime SLA for self-serve tiers
