Hi guys,

I noticed many iPhone users can't access the new AI emoji features because they have older devices. So I spent 48 hours building an accessible alternative using open-source images models.

The system uses a fine-tuned Flux AI model (based on https://github.com/kijai/ComfyUI-FluxTrainer) to generate custom emojis from text. It runs efficiently enough to work on a basic web interface - no device requirements or OS updates needed.

Just type what emoji you want (like "happy pizza doing backflip"), and it generates a vector emoji with transparent background in about 5 seconds. Works on any device with a web browser, including older iPhones.

iOS and android versions are coming, and would love your feedbacks on the tools. Love to hear if something else interesting you would like to see on the too,

Cheers, //TT

Looks cool, although i personally stopped at the login prompt. I would probably also tone down the continuous generic pop-up that someone generated something. It seems a bit too frequent, repeating and generic to be trustworthy.

That being said, I like the use-case and it seems like nice work in a short amount of time. I have a couple of questions that I am curious about

1. Can you elaborate a bit more on your fine-tuning process? Did you "just" feed the model a bunch of regular emojis? Have you considered using any RLHF/DPO approaches?

2. You mention you generate a vector emoji. As far as I know the flux model just generates bitmaps, how do you handle that conversion?

Thank so much for your feedbacks. I think I may need to open up 1 generation for people without logging in. I toned down the pop-up completely now. 1. yes, right now it is bunch of images with data. I will be looking into RLHF/DPO when I have more time and finance, since it is costly. 2. I tried to train it based on a lot of vector images, and also do some optimization on my back-end too.

Thanks

Thanks for elaborating!

Please reach out once/if you start looking into further refinement (my email is in my profile). I am with a startup specializing in collecting preference data quickly and efficiently - so efficient that we even offer a free demo (https://app.rapidata.ai/compare). Feel free to hit me up and I will make sure you get a good deal.
