Transformer
The neural network architecture that powers most modern AI language models.
In Plain English
The Transformer is a type of neural network architecture introduced in 2017 that revolutionized AI. It's particularly good at understanding relationships between words in text, even when they're far apart. Transformers can process text in parallel (all at once) rather than word-by-word, making them much faster. Nearly all modern language models — including GPT, Claude, and Gemini — use transformer architecture.
💡Real-World Example
The "T" in GPT and the "T" in BERT both stand for Transformer — it's the foundation of today's AI assistants.
