🧬Understand Multimodal Models
Crack open the three real fusion patterns — early, late, and joint — so when you face a multimodal task at work, the choice between vision, OCR, or both becomes mechanical instead of guesswork.
Phase 1What 'Multimodal' Actually Means
See why text-only models can't reason over images and what 'modality' actually means
A modality is a data shape, not a content type
6 minA modality is a data shape, not a content type
Text-only models can't see — they can only describe

Every multimodal model is one of three architectures

Image patches become tokens — that's the whole trick

Phase 2Three Ways to Send a Chart
Send the same chart three ways and watch each strategy's strengths and blind spots emerge
One chart, three input strategies, three different answers

Send the raw image and watch where it shines

OCR-only is precise about text and blind to layout

Image + caption is the production-grade default

Phase 3Inside the Fusion Architectures
Trace how vision encoders, audio tokenizers, and text get stitched into a shared space
A vendor pitches you a 'super accurate vision model.' What do you ask?
