Baby4D, an AI tool powered by FLock that transforms 4D ultrasound scans into lifelike baby portraits. Our Chief of Staff, @sameeha_rehman, spoke with Dr. Ken, founder of Baby4D, to learn more about the ideas and tech behind it 🔽 🎧On Apple Podcasts:

3/ The idea came from a personal moment. Dr. Ken’s wife saw how hard it was to connect with the blurry, golden-hued images from a 4D scan of her own child. That disconnection led to a question: "what if parents could see something more real, something that feels like their baby?"

4/ Under the hood, Baby4D runs on advanced diffusion models, guided by ControlNet. The system analyzes ultrasound data, captures key facial markers (like bone structure and spacing of features), and renders a realistic image -down to skin tone and hair texture.

5/ The process is simple: parents upload a 4D scan via web app, select personalization details like gender or skin tone, and receive a photo within minutes. Compared to manual services that take days, Baby4D is fast, accessible, and fully automated.

6/ Built on FLock's decentralized AI training platform, Baby4D keeps privacy at its core. All ultrasound data is anonymized, never stored long-term, and never passed to external systems. The pipeline is closed, secure, and purpose-built for responsible AI deployment.

7/ The vision is bigger than portraits. Baby4D is expanding into customization, exploring age progression, and teaming up with clinics to bring emotional connection into the medical journey. This is FLock’s trained models in action, powering real-world applications.
