LLM Evaluation Metrics Explained: Accuracy, BLEU, ROUGE, and More

llm evaluation metrics explained with examples

LLM Evaluation Metrics You Should Know Evaluating large language models (LLMs) is harder than it looks. Unlike traditional software, you cannot measure performance with a single number. Instead, you need a combination of metrics that capture accuracy, fluency, reasoning, and real-world usefulness. The most important LLM evaluation metrics include perplexity, BLEU, ROUGE, accuracy-based benchmarks, and […]

Context Engineering vs Prompt Engineering: Explained Simply

context engineering vs prompt engineering comparison diagram

Context Engineering vs Prompt Engineering: What Changed? Prompt engineering used to be the main way to control AI outputs. Today, that is changing. Modern AI systems rely less on carefully crafted prompts and more on context engineering—a broader approach that includes memory, tools, retrieval, and structured inputs. The shift is important because it changes how

Role of Vector Databases in RAG : Explained Simply

Role of Vector Databases in RAG Explained Simply: vector database role in rag pipeline diagram

Role of Vector Databases  in  RAG Pipeline Vector databases are one of the most critical components in a RAG (Retrieval-Augmented Generation) pipeline. They are responsible for storing and retrieving embeddings—numerical representations of text—so that an AI system can find the most relevant information before generating a response. Without vector databases, RAG systems cannot efficiently search

What is Prompt Injection : Examples, Risks, and Why It Matters

What is prompt injection: AI prompt safety diagram with prompt injection risks

What Is Prompt Injection? Examples and Risks Prompt injection is a security and reliability problem where an AI system follows untrusted instructions that were hidden inside user input, documents, webpages, or tool outputs. In simple terms, the model gets told to do one thing, but a malicious or unintended instruction inside the context tries to
