I was torquing the saddle clamp down, and the bit broke off. Luckily it seems like it’d been torqued enough before snapping, so I can ride the bike for now. How would I be able to remove the bit that’s now stuck inside the clamp bolt?

it seems your torque wrench is broken
Go for a ride and see if it’s still there at the end.
I would drill through it if you can. if you can’t drill a hole in the middle of the bit and you might be able to pry it off
Get a strong magnet, that helps sometimes.
Strong magnet? Depends on how much it deformed before snapping
I think the first thing to try is a little neodymium magnet and see if you can get it to nudge like 1 millimeter out, then you can scrape it with a seal pick and get it to back out a couple more millimeters, then get purchase with channel locks (this sometimes works but it’s the easiest). If that doesn’t work I’d solder a nail to it and try to wiggle it out the same
Throw the bike away

see if it will pop out while riding or banging against the post. If not maybe get a sacrificial bolt or something and glue/blond it carefully only to the stuck piece. Worse case, you will need to use an extractor tool or Dremel out a cross section on the bolt and try to unscrew it.
Try not to lose it, it’ll be gone in hours then.
Looks like the front fell off, that’s not supposed to happen.
Put a small drop of super glue on it and see if you can just pull it out if a magnet fails.
Got a pin vise? Slow but delicate way to drill it out
Easy out
This might require buying some tools, but here’s my idea. From looking at the magnified photo, that Torx bit appears to have deformed. It shouldn’t have, they should be ‘rock hard.’ This might be to your advantage.
Take a hard masonry nail, or a narrow centre punch and place the point vertically above the centre of the broken piece. Tap it with a small hammer and see if you can make a mark. If so, angle the nail/punch to the right a bit and tap it again. The idea is to try and loosen the broken piece in the screw. If you *can* loosen it, you should be able to shake it out.
Get a set of extractor for 5$ on ali express and buy a new cap.
Clean everything with IPA, then lightly grease the head of the screw. Be careful to avoid getting any on the broken bit. Then JB Weld a small, clean screw to the broken bit and allow it to cure overnight. The grease prevents the epoxy from sticking to the bolt head. May need to put your bike on its side so the screw doesn’t fall off when the epoxy is setting. Then pull the screw and the broken bit should pop out.

Strong magnet
plastic mallet on the other side. gently

What were you torqueing it to? I’m surprised that a T25 bit broke at any torque on a bike. Unless the bit was previously broken and basically being held on by a thread.
Its usually not in the very hard but just sort of clamped in the position. If you tap it with a chisel in the opposite direction of removal it should just fall out
Buy a new seat & seat post !
I’d drill it and jam a screw in to lever it out with.
