### AI overview

A Meta Tech Podcast episode discusses how Facebook Reels engineers built Friend Bubbles, a feature that highlights Reels watched and reacted to by a user's friends. The episode covers the machine learning model behind the feature and differences between iOS and Android user behavior.

### Source excerpt

On its face the new Friend Bubbles feature looks simple enough. It highlights Reels your friends have watched and reacted to. But sometimes the features that seem the most straightforward require the deepest engineering work. On this episode of the Meta Tech Podcast, Pascal Hartig chats with Subasree and Joseph, two software engineers from the Facebook [...] Read More...

### AI overview

A Meta Tech Podcast episode discusses AssetGen, a foundation model for 3D assets. Meta's XR Tech team explains how it was built and trained, the role of LLMs in VR, and efforts to generate complete 3D worlds from text prompts.

### Source excerpt

Imagine being able to use AI to create 3D virtual worlds using prompts as easily as you can generate images. The intersection of AI and VR was one of the biggest topics at Meta Connect this year. In his keynote, Mark Zuckerberg shared his vision of a future where anyone can create virtual worlds using [...] Read More...
