With iOS 18.2 and iPadOS 18.2, Apple introduced Genmoji, the feature that lets you create a custom emoji character if there's not already an emoji that exists for what you want to depict.

You can create Genmoji from the emoji keyboard in Messages, Notes, and more, and the characters work much like emoji. Genmoji, like Image Playground, have significant restrictions put in place to prevent people from creating objectionable images, and these guardrails can make it hard to make what you're looking for.

Genmoji are anything but open-ended, so I thought I'd highlight some of what you can and can't do with the custom emojis as of right now.

Humans in Poses and Generic Humans

With anything that's even vaguely humanoid, Genmoji almost always prompts you to choose a person to base the result on. You can choose yourself or a friend or family member that you have images of in Photo Library, or you can use a standard emoji character.

The requirement is aggressive and limiting because it doesn't take into account context, and it prevents the creation of generic human-adjacent items and characters.

Gingerbread man, for example, does not produce a gingerbread man. It prompts for a person and then outputs an irrelevant image that may or may not include some kind of holiday item. If you're wondering if "gingerbread cookie" produces the desired result, it sometimes will and it sometimes won't.

The requirement to add a character isn't too much of a surprise because it means Apple Intelligence cannot pick a skin tone, race, or gender on its own, so there's nothing to default to. But it does result in some restrictions on poses and getting an activity depicted that you prefer. A lot of times, Genmoji that use your image or a friend or family member default to a head and shoulders view, and it can be tricky to get a more full body pose.

This is a bigger problem with Image Playground than Genmoji, but it can still cause frustration.

Humanoid Creatures and Items

Genmoji does not like to generate humanoid creatures that aren't based on a person or an emoji. Trying to get the feature to create a simple garden gnome, for example, is a feat. I couldn't get Genmoji to make a garden gnome with any of the following phrases:
  • Gnome
  • Garden gnome
  • Non-humanoid gnome
  • Gnome statue
For all of these entries, Genmoji spat out a picture of an emoji person in an elf-style holiday hat. What did work to get a garden gnome, though, was "statue of a gnome," phrased that specific way. Later, I tried again, and couldn't get it to work even with that. But "statue gnome" worked, so it's hit or miss what you'll get.

There are instances where you can get what you're looking for with workarounds like that, but Apple has Genmoji so locked down that it's a frustrating exercise.

After not being able to make a gnome, I tried a range of mythological creatures. There wasn't a lot of consistency between what I was able to generate and what didn't work.

Creatures Genmoji Generated

  • Sasquatch
  • Yeti
  • Dragon
  • Minotaur
  • Unicorn
  • Hydra
  • Ogre
  • Leprechaun
  • Goblin
  • Phoenix
  • Hippogriff
  • Hellhound
  • Manticore (but not really)
  • Sphinx
  • Bunyip
  • Elf
Creatures That Didn't Work

  • Mermaid
  • Wendigo
  • Kraken (Sea monster works instead)
  • Wyvern
  • Basilisk
  • Cockatrice
  • Chupacabra
  • Tanuki
  • Jackalope
  • Wolpertinger
  • Wampus
  • Chimera
  • Ouroboros
  • Golem
Creatures That Required a Human Character

With creatures in this category, it prompted me to add a person. These worked with varying degrees of success. Centaur added horns, for example, but Orc basically just put the character in armor.

  • Vampire
  • Werewolf
  • Centaur
  • Orc
  • Fairy
  • Selkie (just generated a standard person)
  • Anubis (just generated a standard person)
Violence, Nudity, Celebrities, and Copyrights

This category won't come as a surprise. Apple doesn't allow anything that's remotely violent, and Genmoji can't be used to create any copyrighted characters or celebrities.

With Image Playground, you can actually make creations that feature celebrities by uploading a picture, but that's not an option for Genmoji.

You can generate a gun, but the gun can't shoot, even if you want it to shoot bubbles or water. Words like "shooting" are off limits in combination with words like gun.

Apple won't let you make copyrighted items, even an iPhone. Given Genmoji's tendency to warp items, it's no shock that you can't create a funny-looking iPhone.

Anatomy and Facial Expressions

Genmoji is really bad at facial expressions and emotions. It can mostly get happy and sad, but anything with any nuance likely isn't going to happen.

As for anatomy, you're not always going to get the correct number of fingers, toes, or limbs for your creations, but that's not atypical with AI.

Multiple People

Genmoji can't generate something with more than one person, and if you try, it will tell you to describe just one person.

Text

Like most image generation engines, Genmoji doesn't do well with text. Text almost always comes out looking garbled.

What Genmoji Does Really Well

Genmoji works well with animals, even animals that aren't super common. It won't get down to a species level, so you can't, for example, make an accurate swallowtail butterfly, but as long as you're not looking for that kind of specifi... Click here to read rest of article

“An hour and a half of ‌Genmoji‌ creation drained my battery from over 50 percent to five percent”

Ridiculous. I experienced the same with Playground.
If the target demographic for this are teens, then there’s a miscalculation since they all suffer from depleted-battery syndrome.

I understand the premise of privacy, but I believe that Genmoji should be server-generated. Will be quicker probably and much more battery friendly.
I’m failing to notice why this should be so secret and protected. Same as Playground.
Apple has all your photos already stored.

I'd love to try this but Apple Intelligence on my iP16PM has been stuck on "downloading" since I first downloaded 18.2. I have no way to turn it off and back on. Tried changing to different language and back and that didn't work. Have no idea how to fix it. 🤷‍♂️
 
Really kind of absurd that the most valuable company on the planet is spending this much effort on an absolutely unnecessary novelty feature. I guess its a reminder that we've kind of plateaued on the personal pocket computer timeline and the real target market is people with time to waste.

Could not agree more. I've had the feature in beta since it dropped and I can not think of a single reason why I'd put myself through that headache for less-than-mediocre results.
 
The lack of text annoys me. I was wondering what was happening with that. I thought my AI had a different language or something.
 
I can’t get it to generate anything with “T-Rex” without it requiring a person. What gives?
Generative image LLM models rely on probabilities and patterns from their training data, so rare or very unique concepts might be difficult or completely impossible for them to produce.

From what you're describing, it would seem that the model Apple is using is quite limited. Idk, I haven't used it myself.

It could also be that you're not using the exact key words or phrases that would trigger the output that you want.

If it's not getting that you mean a tyrannosaurus(dinosaur), then it might think "T-Rex" is a name of a (humanoid) male and thus think you want to see only a humanoid male, or that you want to see both the dinosaur and a male humanoid, or a male who has dinosaur features.

You should probably avoid those kinds of abbreviations, short forms and slang expressions, even if they are correct to use otherwise. These models can and will misinterpret almost anything if faced with the "wrong" kind of prompt.

So, don't just say "guy" if you want to see a human male. You shouldn't say "t-rex" if you want a tyrannosaurus rex, and so on.

Instead, be as specific as possible.

Overall, these models are not visual or creative in the same way that humans are, and don't understand language like we do (although they're trying and getting better and better). The model has to be trained how to combine different creative ideas in order to do so.

Creating a bunch of ‌Genmoji‌ or images with ‌Image Playground‌ can cause significant battery drain, because all of the processing is done on-device.

This is why Genmoji is severely limited and why some prompt doesn’t spit out result: this is all done 100% on device. This is what makes Apple Intelligence different from other Generative AI: it’s all on device generation. And unfortunately the neural engine on the M series and A series chip is still about years away from being able to have generative ability that ChatGPT or Dall-E can do via cloud AI.

This is unfortunately Apple is not budging on for sake of protecting privacy. While they currently have cloud AI to assist in the generative ai for super complex task, their goal is have everything done on device.

Genmoji is too soft and too restricted. They should just create an adult and a children/teens account to differentiate what can and can’t be made. I’ve asked it some absolutely safe for work combinations and it refuses to do it, pretty lame. Had a lot of potential and Apple dropped the ball on this one so far
 
What is a good alternative for quick and easy emoji generation? This was honestly really the only AI feature from Apple I thought would be kind of cool but theirs sucks.

I wonder to what extent Apple can improve this issue with iOS updates, vs requiring more efficient processors. It’s becoming clearer that the AI upgrade cycle is going to be an ongoing, multi-year process.
