📝 Editorial: Apple Goes Small and Super Multimodal

Apple has been late to the generative AI game, but lately, it has been pushing the research agenda quite hard. Apple has an ideal playground for innovating in one of the hottest areas of the next wave of generative AI: on-device multimodal models. The idea of powering mobile AI through API integrations with massively large foundation models seems highly impractical and insecure, and Apple is in a unique position to power alternatives to this paradigm. However, most of Apple’s efforts in small on-device models have been somewhat underwhelming.

That definitely changed last week. Building on recent research, Apple published a paper and unveiled a demonstration of 4M-21, an any-to-any vision model trained for many tasks and modalities. 4M-21 builds on the original 4M research; the new model expands from 7 to 21 modalities, including highly specific ones such as edges, geometric, semantic, and feature maps. Perhaps the biggest contribution of 4M-21 is the ability to train a single model across language and vision simultaneously without virtually sacrificing performance. The secret? A series of modality-specific tokenizers that not only optimize multimodal learning but do so without the known challenges of large models.

4M-21 is impressive, and its approach seems to address the key first principles of the type of models needed in iOS devices. In case it's not obvious, Apple is no longer quiet in generative AI.
