Vector search in PostgreSQL has gone from “experimental hack” to a serious production option, largely thanks to the pgvector extension. But as teams push from thousands to tens or hundreds of millions of embeddings, a natural question emerges: How do you keep vector search fast and cost‑effective as the dataset grows, without adding yet another external database? This is exactly the problem pgvectorscale is designed to address. In this article, we’ll take a detailed look at pgvectorscale: what it is, how it fits into the Postgres ecosystem, how it scales vector search, and what trade‑offs you should understand before using it. ...

Large Language Models have revolutionized artificial intelligence, enabling machines to understand and generate human-like text at scale. But not all LLMs are created equal. Understanding the different types, architectures, and approaches to LLM development is essential for developers and AI enthusiasts looking to leverage these powerful tools effectively. This comprehensive guide walks you through the landscape of Large Language Models, from foundational concepts to practical implementation strategies. Table of Contents What Are Large Language Models? Core LLM Architectures LLM Categories and Classifications Major LLM Families and Examples Comparing LLM Types: Strengths and Weaknesses Choosing the Right LLM for Your Use Case Practical Implementation Tips Top 10 Learning Resources What Are Large Language Models? A Large Language Model (LLM) is a deep learning algorithm trained on vast amounts of text data to understand, summarize, translate, predict, and generate human-like content.[3] These models represent one of the most significant breakthroughs in artificial intelligence, enabling applications from chatbots to code generation. ...

Introduction Small Language Models (sLLMs) are quickly becoming the workhorses of practical AI applications. While frontier models (with hundreds of billions of parameters) grab headlines, small models in the 1B–15B parameter range often deliver better latency, lower cost, easier deployment, and stronger privacy—especially when fine‑tuned for a specific use case. This tutorial is a step‑by‑step, implementation‑oriented guide to working with sLLMs: What sLLMs are and why they matter How to choose the right model for your use case Setting up your environment and hardware Running inference with a small LLM Prompting and system design specific to sLLMs Fine‑tuning a small LLM with Low‑Rank Adaptation (LoRA) Quantization and optimization for constrained hardware Evaluation strategies and monitoring Deployment patterns (local, cloud, on‑device) Safety, governance, and risk considerations Curated learning resources and model hubs at the end All code examples use Python and popular open‑source tools like Hugging Face Transformers and PEFT. ...

Table of Contents Introduction Probability Fundamentals Conditional Probability and the Chain Rule Probability Distributions How LLMs Use Probability From Theory to Practice Common Misconceptions Conclusion Resources Introduction If you’ve ever wondered how ChatGPT, Claude, or other large language models generate coherent text that seems almost human-like, the answer lies in mathematics—specifically, probability theory. While the internal mechanics of these models involve complex neural networks and billions of parameters, at their core, they operate on a surprisingly elegant principle: predicting the next word by calculating probabilities. ...
