What to watch for on the bill
- Confusing v1-vs-v2 split with different features, prices and regional availability
- Add-ons such as speaker diarization cost extra and are not transparently documented on the public pricing page
- Effective bill often exceeds the headline $0.016/min once GCP overhead and add-ons are counted
- Requires a full Google Cloud account, billing and ADC auth setup rather than a single API key
