Seeing is not reading.
A model can describe a chart accurately and misread the number printed on it.

Multimodal Models: Text, Image, Audio, Video
Learn what multimodal models can genuinely do across image, audio and video, and where they quietly fail. Free, one sitting.

Why this matters
Whole categories of product became possible the moment a model could read a screenshot or transcribe and reason over a call. But each modality brings its own failures — small text in images, speaker confusion in audio, missed detail across video frames — and none of them announce themselves.
What you'll cover
One Model, Several Senses
- What multimodal means
- Everything becomes tokens
- What this unlocked
- Cost across modalities
- Choosing the right input
Working With Images
- Describing a scene
- Reading text in images
- Charts, tables and diagrams
- Screenshots as input
- Verifying what it saw
Working With Audio
- Transcription quality
- Speaker confusion
- Names, numbers and jargon
- Reasoning over a call
- Audio in and audio out
Video and Its Limits
- How video is processed
- What gets missed
- Cost at video scale
- Practical video use cases
- When to use something else
Designing Multimodal Features
- Routing by input type
- Normalising early
- Per-modality fallbacks
- Interface considerations
- Testing across modalities
What you'll understand
- Say what each modality realistically supports today
- Spot the failure modes specific to image and audio input
- Choose the right input format for a task
- Design fallbacks when a modality underperforms
A look inside
Three moments from this Quick Lesson
The real thing — not a mockup of it.
How it fits
Image / Audio / Video → Tokens → Same context window
Every modality is converted into tokens, and every modality competes for the same limited window.
Apply
Where is image input least reliable?
Describing the overall scene
Reading small dense text or precise figures
Identifying obvious objects
How it works
01
Understand the concept
A plain-language walkthrough of the idea itself, no prior context assumed.
02
See it in practice
A simple diagram or example showing how it actually fits together.
03
Apply what you learned
One quick check that you can recognise it, not just recall it.

Frequently asked
Can I just send a screenshot instead of text?+
Often yes, but text you already have is cheaper and more reliable than an image of the same text.
What will I learn?+
What image, audio and video input support today, their distinct failure modes, and how to design around them.
Is this Quick Lesson free?+
Yes. Quick Lessons are free, short, and do not require a paid plan — sign in only to save your progress.
