An AI that’s only ever seen pictures and text can now mix perfumes better than the pros, even though it literally can't smell.

AromaGen: Interactive Generation of Rich Olfactory Experiences with Multimodal Language Models

The Takeaway
By learning the 'language' of chemistry from data, the AI has mastered the ability to create perfect replicas of food and scent aromas. This shows that physical senses like smell can be digitally mastered even without physical experience.
From the abstract
Smell's deep connection with food, memory, and social experience has long motivated researchers to bring olfaction into interactive systems. Yet most olfactory interfaces remain limited to fixed scent cartridges and pre-defined generation patterns, and the scarcity of large-scale olfactory datasets has further constrained AI-based approaches. We present AromaGen, an AI-powered wearable interface capable of real-time, general-purpose aroma generation from free-form text or visual inputs. AromaGen
