If you want to use AI to try to forecast what your baby will look like, OurBabyAI is a notable service. This AI-powered baby generator will produce 8 HD images of a child it thinks you might have, blending features from your input photos. The service requires good quality photos, but the process is quick and easy, producing results in seconds. So far, more than 1,300 families have used OurBabyAI, and it's a fun way to imagine what your child might be like while keeping your privacy by deleting the photos you upload after the service is done.
If you want more general face generation abilities, you can also check out Face Studio. It's not a baby-face predictor, but it can generate photorealistic human faces in a few seconds. Face Studio has a batch generation feature so you can generate a group of faces with specific demographic characteristics. It can produce high-fidelity, realistic results, and you can use it through a free plan or a professional subscription.
