There are probably more, but I will focus more on world record runs, let me know if I missed some!

Blood Money 6:40 Normal Co-op by magicbrave46 and amazingms; uses the old spinning glitch that allowed you to clip in the elevator, which saves enough time to activate the elevator without having to get in after it opens. You used to be able to do this with reviving someone in the direction of the elevator and getting them in (revive clipping), but that also got patched two months ago.

Brick Bank 10:16 Normal Solo by nekothechan; gets inside the vault area and activates the drill early using the already mentioned patched revive clip glitch (You can do that glitch solo if you find a way to down yourself like blowing yourself up, and hitting the 50% chance of the skill "Morale", which moves you back)

Brick Bank Normal Co-op 10:42, 10:45, 10:45 and 10:50; same thing as earlier, just uses a teammate to revive through the timelock door instead.

Brick Bank Nightmare Co-op 11:41, 12:08, 12:14; same thing as earlier.

Downtown Bank Normal Solo 5:07 runs; uses that glitch and lets you take the two necessary bags to escape right away, without glitches that time is not possible since you don't have enough time to bag both of them & escape in time, although this is possible in co-op in the same difficulty.

Downtown Bank Nightmare Solo 5:11, 5:43 and 5:50; same thing as earlier, this one being more obvious as you'll have to take 7 bags.

Downtown Bank Nightmare Co-op 5:07, 5:10 and 5:15; same.

Golden Mask Casino Normal Co-op 2:34 and 2:36; glitches inside the vault using the revive clipping glitch to take the 5 necessary bags early.

Golden Mask Casino Nightmare Co-op 2:36; same thing, just with 10 bags.

RO-Bank Normal Co-op 5:21 and 5:29; Gets inside the vault early using that one patched evil grrrr glitch.

RO-Bank Nightmare Co-op runs 5:53, 5:59 and 6:10; Glitches inside the vault to either open the deposit boxes early or for the fastest ones, to get money bags ready.

The Ozela Heist Normal Co-op 3:58 and 4:21; Gets inside the vault and stage area room early before they're available, saving both dialogue and skipping the walk to the winch.

The Ozela Heist Nightmare Co-op 4:01 and 4:11; exactly same thing as earlier grrrrrr evil glitch.
