Before it
Multimodality was added to text models afterwards, by bolting on an encoder.
The problem
A bolted-on encoder limits how deeply modalities can interact.
What it introduced
A model family trained on text, images, audio and video from the start, across three sizes.
Why it matters
It established native multimodality as the frontier design and put Google back in direct competition.
What modern models inherit
Natively multimodal training rather than adapter bridges.
What came next
Gemini 1.5's million-token context, then the 2.5 and 3 generations.
