I have a glass induction cooktop that works fine, but the corner has cracked and fallen off. The corner was crushed into several pieces, so I (perhaps mistakenly) threw the pieces out.

Here's a photo of what it looks like now:

enter image description here

The missing part forms a roughly equilateral triangle with 3cm sides. Note the bezeled edges, of the cooktop, which taper off slightly.

If this were drywall I'd have no qualms about touching it up and painting over it but I don't have experience patching up glass like this.

Any ideas for how to make it look presentable again? Note that the corner of the cooktop doesn't get searing hot, although obviously it will get warm while cooking.

An alternative solution is to silicone seal all round (this is often done with similar glass cookers, depending on the worktop) and just build up the sealant in this corner. Normally I use clear sealant, but black is available and would be best here, if applied very tidily

Realistically, no, unless you are fine with a repair that's obviously a repair.

If it does not get too hot, you might be able to make a mold of one of the other corners and use it to form epoxy at this corner. That might well break again, or prove to be too hot after all, and would almost certainly be visible as being not like the others.

As it's basically cosmetic, evidently, I'd suggest leaving it alone as likely being the best option.

I can see that you are displaying a hole on your kitchen's top, so I'd better first seal it up asap to avoid cooking water, or humidity, leaking down.

That said, it won't likely be possible to restore, at least esthetically, the cooktop for a couple of reasons: being made of hardened glass (ceramic glass), and given the extent of the damage, you can't just use an epoxy filler, you should use the same material to reconstruct the triangle. And even if you were successful, having the same partially-opaque colour is mostly impossible to achieve unlike drywall.

In the drywall example, you can use a filler to reconstruct entire sections, and then when you put water-based paints you end up with a tiny visible spot or have to repaint the whole wall (YMMV).

Finally, I'd make sure that the cracks are not sharp enough to harm a kid, this is where a glass epoxy filler has more utility (you can find it at DIY shops)
