I'm trying to understand exactly how **Bring Your Own Key (BYOK)** works across all license tiers.

Since BYOK is included with **Tier 1, Tier 2, and Tier 3**, what features does it actually unlock?

Specifically:

1. Does BYOK replace the included AI credits for **all AI features**, or are some features still limited by credits?
2. Does BYOK work for **AI video generation** on every tier, or is video creation restricted to certain license tiers?
3. If I connect my own API key(s), can a Tier 1 user access the same AI/video capabilities as Tier 3, with the only differences being brand accounts, user seats, and storage?
4. Are there any AI models or video features that remain exclusive to higher tiers even when using BYOK?

I'd like to understand exactly what BYOK covers before deciding which lifetime tier makes the most sense.
