Snapchat has added a new generative AI feature to its app. Called “Dreams,” it’s in some ways similar to the company’s signature AR effects, known as lenses. But instead of real-time camera-based effects, the feature uses generative AI to remix users’ selfies into “fantastical images that transform their persona into new identities.”

The feature, which can be found in the app’s “memories” section, begins by asking users to take selfies showing their face at different angles. The app will then creates a series of eight images based on themes like “time travel” or “alternate universes.” Eventually, Snap says, users will be able to create Dreams that include their friends’ likenesses as well.

Dreams is the latest generative AI experiment from the company, which launched its MyAI chatbot earlier this year using OpenAI’s models. (Dreams uses open source tools and internal data, though the company hasn’t provided details about specific partners.)
