First up, GIF suggestions. If you're in a group or one-to-one conversation and type a common expression such as "I love you" or "thanks", a GIF picker bar will appear, automatically showing GIFs that correspond to that phrase. It's a fun addition. M suggestions for quick replies is a bit more useful. If you're asked a straightforward yes/no question in a one-to-one chat, the function offers quick reply options "yes", "no" or "I think so". Which is helpful if you're trying to make plans but can't dedicate real time to looking at your phone.

Finally, there's M suggestions for Fandango's new chat extension. If someone in your chat suggests seeing a movie, M will suggest you open the chat extension to find a film, watch a trailer or look up show times, which can then be shared back to the chat with a simple tap. You'll also be able to buy tickets directly inside Messenger, a function that aligns the service with Facebook's original M aspirations. M is AI-powered, so the more you use it, the better it'll learn how to help. But if you get bored of the GIFs, it's easy to mute the service, too.
