GPT-4o: an AI that sees, hears, and speaks

In May 2024, OpenAI unveiled GPT-4o —the “o” is for omni— and changed the conversation about artificial intelligence. Until then, most people thought of AI as something you write to and it responds with text. GPT-4o showed something different: a model that sees an image, hears your voice, and responds by speaking, almost in real time and in the same flow.

The eye-catching part was the demo. What matters, for your company, are the use cases that become possible when AI stops reading only text.

What “multimodal” means (without the jargon)

Multimodal means that a single model understands several types of information at once: text, images, audio. You no longer need one tool to transcribe, another to read an invoice, and another to reply. A single one can see, hear, and answer.

For a business, that eliminates the “seams” between systems that used to have to be stitched together by hand.

Five use cases for your operation

• Read documents just by photographing them. Invoices, delivery notes, receipts: AI extracts the data from an image without manual entry.
• Voice service, 24/7. An assistant that listens to the customer and responds by speaking, for simple queries.
• Visual support. The customer sends a photo of the problem and AI guides the first response.
• Internal training. Explain processes from screenshots or photos of equipment.
• Quality control. Compare an image against a standard and flag differences.

The question is no longer “can AI write?”, but “which process in my company improves if it can also see and hear?”.

Your first multimodal case

You don’t need to rebuild your operation. Choose one process where someone today spends hours looking at images or listening to audio and transcribing by hand. That’s where multimodal pays off quickly.

Start small, measure the results, and keep a person reviewing what matters. That way AI isn’t an impressive demo: it becomes part of how your company works.
