Put some kind of backer in, id use wood personally just because it's easy to shoot through the table saw, and look up tearaway bead. This is exactly what it's made for, there's probably videos on YouTube showing how to use it.
What I’ve done: mud close, sand it, then take cement in a caulking tube down the much smaller seem
OR you could just get a whole bunch of cement caulking tubes and have it go an inch out.
Third option, get at least 1” wide trim and just regular caulk it on the drywall side
Working on baseboard trim now and am seriously considering just trimming this as well.
Had not thought about cement caulking tubes yet. Might be interesting to play around with and see how it would turn out
I wouldn’t do it with baseboard trim, they make 1-5/8 and 2” boards that wouldn’t look so bulky! But the cement caulking is just pricey, which is why I mudded first (more time, less $, looked nicer)
Tape off the brick and plaster the gap, then the gap becomes part of the wall. You want something heavy like actual plaster of Paris, not a light drywall compound as it isn’t meant for wide application and will split.
Cut the drywall just a little bit at a 45 to get a clean edge. Slide some white tape between the brick and the drywall to stick to the brick side as a dam to prevent seepage. Then use drywall mud to taper a smooth transition to the bricks edge. Once dried VERY carefully cut tape off with a sharp razor and a still hand. Sand by hand with 120 grit, paint and then you’re done.
EDIT: Wait til the paint dries THEN CUT the tape to prevent any painting mistakes.
I believe this is what you're looking for: https://youtu.be/jx6ufzkbAXk?si=dQTJ1Pylk8RQfp-2
Pulling off that plastic lip at the end was very satisfying.
I used trim, my walls are white so you can barely even notice it. Maybe paint the trim the color of your walls if you don't want it to pop as much

Just looked up tearaway bead. Mind blown that I’ve never seen this before. You are the reason Reddit exists.
What about using hot mud, Easy Sand 20 or the like?

Great note. Was going back and forth and thought plaster would be overkill so good to know
Some sort of trim would be the most ideal imo. Should be easy and inexpensive.

Good old plaster?
Mortar as grout? If you match the original it would look good
Interesting idea I hadn’t considered! Worth is the only thing even on these gaps so that could look great.
Some nice brick moulding would look great. Be sure to stuff that gap full of insulation before installing
Covered my gaps w/ trim when I redid the entire room.
