What is Neural machine translation (NMT)?

Neural machine translation is like having a super-smart friend who can talk to you and also speak another language fluently.

Imagine you have a notebook where you write down what you're saying in your own language, let's say English. Now, your smart friend looks at that notebook, understands exactly what you mean, and then writes the same message in another language, like Spanish, in their own special notebook. This happens all at once, not word by word or sentence by sentence.

Think of your friend as a translator robot who has been learning both languages for a very long time. It doesn’t just know words; it knows how sentences are put together and what makes sense in each language. So when you say something like “I like ice cream,” the robot thinks, “Okay, that means ‘Me gusta el helado’ in Spanish,” and writes that down.

This robot friend gets better over time, it learns from every message you send, just like how you get better at drawing by practicing a lot. That’s why translations today feel more natural and easier to understand than ever before!
