Go Viral! How to Create Your Own Adorable (and Free!) AI Baby Video

Published: May 16, 2025

You’ve probably seen them popping up all over your social media feeds – hilarious and surprisingly realistic baby versions of your favourite celebrities, podcasters, or even your friends, animated and talking! It’s the latest AI trend taking the internet by storm, and guess what? You can jump in on the fun and create your own, for FREE, without needing a degree in computer science.

This guide will walk you through, step-by-step, how to transform a photo of yourself into an adorable baby version and then animate it using a couple of powerful (and free-to-try) AI tools. Get ready to make your friends giggle!

What You’ll Need:

  1. A clear photo of yourself (a headshot works best).
  2. Access to ChatGPT (the free version is fine).
  3. Access to RunwayML’s Act-One tool (they offer a free trial/credits).

Let’s get started!

Step 1: Creating Your Baby Persona with ChatGPT

First, we need to generate the baby version of your image.

Go to ChatGPT

Open your web browser and navigate to https://chat.openai.com/. Log in or sign up if you don’t have an account.

Upload Your Photo & Craft Your Prompt:

  • In the message bar, click the attachment icon (it looks like a paperclip) to upload your chosen photo.
  • Once your image is uploaded, type in the following prompt:
    “Generate an image but as a realistic looking baby version of the person. Please give me an image in landscape format.”
  • Pro Tip: If you have any distinct features you’d like the baby version to keep (like a beard, glasses, etc.), add that to your prompt! For example, I wanted to keep my beard, so I added: “Keep the facial hair on them as well.”

Generate and Download

Hit enter (or click the send button) and let ChatGPT work its magic. It will generate a baby version of your uploaded image.

  • If you’re not quite happy with the first result, you can ask ChatGPT to try again or slightly modify your prompt.
  • Once you have an image you love, click on it to enlarge it, and then download it to your computer.

You now have your adorable baby picture! Time to bring it to life.

Step 2: Animating Your Baby with RunwayML’s Act-One

RunwayML has an incredible tool called Act-One that can take a source image (your baby pic) and animate it based on a “driving video” (a video of you talking/making faces).

Go to RunwayML & Sign Up:

  • Navigate to RunwayML’s Act-One feature. You can usually find it by going to https://app.runwayml.com/ and looking for their AI Magic Tools, specifically “Generate Video” and then features related to character animation (Act-One is a model/feature within this). The direct path can sometimes change, but the aim is to get to their video generation tool that supports character reference and a driving video.
  • You’ll need to sign up for a free account. HEADS UP: The free tier on RunwayML usually gives you a limited number of credits or generations. Often, this means you get one good free go at a tool like Act-One. So, make it count! (If you want to make more, you might need to explore their paid plans).

Upload Your Baby Image as Character Reference:

  • In the Act-One interface, look for a section labeled “Character reference.” You might see a “Custom” tab or an upload area.
  • Click to upload the baby image you downloaded from ChatGPT. RunwayML will process it, which might involve cropping or face detection.

Add Your Driving Performance:

  • Now, look for the section to “Add a driving performance.” You’ll typically have two options:
    • Start recording: This will use your webcam to record a new video.
    • Select Asset: If you’ve pre-recorded a video or want to use an existing one.
  • Click “Start recording.” Your browser will likely ask for permission to use your camera and microphone – allow it.
  • A recording window will appear. You’ll see yourself on camera.
  • Get Ready to Perform! You’ll want to record about 5-20 seconds of yourself. Tell a short story, a joke, sing a snippet of a song, or just make lots of expressive facial movements. The more you move your face (smile, frown, raise eyebrows, open your mouth wide), the better the AI can map those movements to your baby image.
  • Click the record button (it usually has a countdown). Perform your piece!
  • Once done, stop the recording. You’ll likely be able to preview it. If you’re happy, click “Use this” or a similar confirmation. If not, you can delete it and try recording again (but remember those free tier limits!).

Generate Your Animated Baby Video:

  • With your baby character reference uploaded and your driving performance video selected, you’re ready to go!
  • You might see options for different models (e.g., Gen-3 Turbo). The default is usually fine for your first try.
  • Click the “Generate” button.
  • Patience is Key: This part can take a few minutes. RunwayML is doing some heavy lifting in the background. You might see a progress bar or a waiting message.
  • Troubleshooting Note: Sometimes, due to high demand, generations on Free Plans can be temporarily unavailable. If you see such a message, you might have to try again later or consider if a paid plan is an option for you.

Download and Share Your Masterpiece!

  • Once the generation is complete, your animated baby video will appear!
  • Preview it. Isn’t it amazing (and slightly uncanny)?
  • Click the download button to save your video.
  • Now, share it on TikTok, Instagram, with your friends, family – wherever you want to spread some AI-generated baby joy!

Tips for the Best AI Baby Video:

  • Clear Source Photo: Use a well-lit, front-facing photo of yourself for ChatGPT. The clearer the face, the better the baby transformation.
  • Expressive Driving Video: Don’t be shy! The more you exaggerate your facial expressions in the RunwayML recording, the more animated your baby will look.
  • Good Lighting for Recording: Make sure your face is well-lit when you record your driving video so the AI can track your features accurately.
  • Landscape is Your Friend: Sticking to landscape format for your initial baby image often makes the video process smoother.
  • Embrace the Uncanny: AI can be a bit quirky. Sometimes the results are perfectly hilarious because they’re a little off. Have fun with it!

And there you have it! You’re now equipped to join the viral AI baby trend. It’s a fun way to play with some cutting-edge technology and get a few laughs.
