Hugging Face AI Updates: April 28, 2026

1. NVIDIA Raw2Insights-US: Physics-Informed Adaptive Ultrasound Imaging

Hugging Face / NVIDIA. NVIDIA published a Hugging Face post detailing Raw2Insights-US, a physics-informed model that processes raw ultrasound RF data and folds in domain priors to produce adaptive imaging that holds up across different probes and acquisition setups. The post is paired with weights and a recipe targeting clinical research teams that have struggled to ship learned ultrasound models because of vendor-specific signal chains. Source

2. Building Scalable Web Apps Around OpenAI’s Privacy Filter

Hugging Face. A new tutorial walks through wiring OpenAI’s privacy-filter mechanisms into a scalable web-app architecture, covering token-level redaction, request-side scrubbing, and patterns for keeping logs clean in regulated environments. It targets teams that already have a Vercel- or Cloudflare-style edge front end and want a defensible privacy story without rolling their own DLP. Source
