hello  
on dev doc, open channel is available up to 100 users.  
but, on the billing plan webpage, it’s 20,000 users.

what’s correct?

Hi @trytoremember,

Both values are correct. There are two types of Open Channels, Classic and Dynamic partitioning. Classic channels have a limit of 1,000 participants where Dynamic partitioning allows for up to 20,000 participants.

Please refer to this docs page about [Open Channels](https://sendbird.com/docs/chat/v3/platform-api/guides/open-channel#2-classic-vs-dynamic-partitioning).
