TL;DR Transformers are neural‑network architectures built around self‑attention , enabling models to weigh the relevance of every token to every other token in a sequence. For Java developers in 2026, they matter because: They power the latest LLMs (ChatGPT‑4, Gemini, Claude‑3) that are being integrated into Java‑based enterprise apps. Java’s ecosystem (DeepLearning4J, ND4J, Eclipse JDT) now offers first‑class support for tensor ops and GPU acceleration. Understanding the core building blocks lets you prototype, fine‑tune, or embed lightweight models without leaving the JVM. Core Concept Why It Matters for Java Devs Scaled Dot‑Product Attention Shows how to replace Python’s torch.matmul with ND4J’s mmul – the heart of any transformer. Multi‑Head Attention Parallel heads map naturally to Ja
