Multimodal LLMs

Modern models that read images and text together.

What you will learn

✓What 'multimodal' means
✓Common vision tasks for LLMs
✓Practical uses like OCR and Q&A

Explanation

Multimodal LLMs (like GPT-4o and Gemini) accept images alongside text, so you can paste a screenshot, chart, or photo and ask questions about it.

They handle OCR (reading text in images), describing scenes, explaining diagrams, and answering visual questions — no separate vision pipeline needed.

For many everyday tasks, a multimodal LLM has replaced building a custom vision model.

Real-world use

Snapping a photo of a broken appliance and asking an AI what the part is — that's a multimodal LLM doing vision.

Common mistakes

• Building a custom model for a simple task a multimodal LLM could already do.
