According to Moderator moves comments to chat - can low-rep user participate?, low rep users are allowed to chat when a discussion is moved to a chat room by a moderator, but not when the chat room is created by someone else.
What about allowing high SME (gold tag-badge holders or >10k users in large sites >5k users on small sites) to automatically "invite" to chat new users / low rep users that have been participating in a post discussion? If so, should this be allowed only on OP's first question or is it something that makes sense to be allowed on any question?
There are several older related feature-requests:
- I'd like to propose that users with high reputation be able to chat with users with low reputation from 2012, votes +50
- Grant chat privs to users who don't have enough reputation yet from 2013, votes +50 (posted as answer -> Propose a privilege to sit in the 500 reputation mark)
- Suggested Privilege: Inviting new users to chat from 2016, votes +22
- Let's make it easier to get a room from 2016, votes +58
At least one of the above posts and other related ones (i.e. allow guests / users without SE accounts, bring chat to 21st century) are included in Magic wand time - what does your community need? from 2021.
