NASA states the mass of TON 618 as 60+ billion solar masses, which I think is based on an earlier estimate. Newer estimates put the mass at 40 billion solar masses.

The theoretical limit for SMBHs is stated as 50 billion solar masses.

Under certain unlikely conditions, they can grow to 270 billion solar masses.

The SMBH in Abel 1201 has not been directly imaged, like Sgr A* and the SMBH in M87 were by the Event Horizon Telescope (EHT) team.
But if we were to use the image of the SMBH in M87 and draw the event horizon of the SMBH in Abel 1201, it would look like this. The event horizon radius is about 16 times that of Pluto and about 4 times the distance to the Voyager 1 spacecraft.

Here is how the SMBH in Abel 1201 compares with these well-known SMBHs.

A group of astronomers, led by Durham University, UK, have updated the mass of the Super Massive Black Hole (SMBH) at the center of gravitational-lensing galaxy Abel 1201 BCG.
The revised estimate of 32.7 billion solar masses (☉), replaces the older estimate from 2017 of 13 billion ☉, making one of the most massive SMBHs,.
The estimate was made using supercomputer simulations of the light from a distant galaxy bent by Abel 1201.

An article being published in "The Astrophysical Journal" reports the results of the study of two galaxy mergers between dwarf galaxies with active galactic nuclei. A team of researchers used data collected by NASA's Chandra X-ray Observatory to discover candidates and then compared them with infrared and optical frequency observations.

Two articles, one published in the journal "Nature" and one in the journal "Nature Astronomy", report different aspects of the study of the most distant supermassive black hole discovered as it devours a star and then emits a jet of materials accelerated at speeds close to the speed of light. The event, cataloged as AT2022cmc, is somewhat similar to a gamma-ray burst but was detected in various electromagnetic bands.
