- Enterprise features like SSO and BAAs require a custom sales conversation rather than self-serve upgrade.
- Free tier concurrency limits (2 TTS, 8 STT concurrent requests) may be restrictive for testing production-like load.
Vagrant
- Vagrant 2.4.3 and later is licensed under the Business Source License 1.1 with IBM Corporation as licensor, not an OSI open source licence
- The Additional Use Grant forbids offering Vagrant to third parties on a hosted or embedded basis in a paid product that competes with IBM's paid versions of Vagrant

- Uses that fall outside the Additional Use Grant require a separately negotiated licence from the licensor
