"Withing 12 months", then "few decades", then put in the mess AGI and artificial superintelligences. Reaching AGI, if ever, won't acheive singularity by itself. And there are more players in the game.
The only prediction that sounds like a big maybe, and with a lot of luck within a year, would be reaching something that will be labeled AGI by some actors. But from there to singularity there may be quite a distance, if ever is achieved.
