Executive Summary As AI adoption accelerates, a critical shift is occurring: organizations are moving from “bigger is better” to “right-sized is smarter.” Our comprehensive analysis of 9 leading models across climate, economic, and healthcare domains reveals: Smaller models (3B-32B parameters) can match or exceed larger models’ accuracy on specialized tasks while using 24x less energy Newer model…
Introduction to KV Caching When large language models (LLMs) generate text autoregressively, they perform redundant computations by reprocessing the same tokens repeatedly. Key-Value (KV) Caching solves this by storing intermediate attention states, dramatically improving inference speed – often by 5x or more in practice. In this comprehensive guide, we’ll: Explain the transformer attention bottleneck Implement KV caching from scratch…
Introduction Autoregressive language models generate text one token at a time. Each new prediction requires a full forward pass through all transformer layers, leading to redundant computations. For example, generating the next token in: [What, is, in,] → [the] requires recomputing attention over [What, is, in,] even though these tokens haven’t changed. KV Caching solves this inefficiency by…
Retrieval-Augmented Generation (RAG) is quickly redefining how we build and deploy intelligent AI systems. It isn’t a replacement for large language models (LLMs)—it’s the missing piece that makes them useful in real-world settings. With hallucinations, outdated knowledge, and limited memory being persistent LLM issues, RAG introduces a smarter approach: retrieve factual information from reliable sources,…
Large Language Models (LLMs) come in various optimized forms, each designed for specific use cases, efficiency, and performance. In this guide, we’ll explore the different types of LLMs (like distilled, quantized, sparse, and MoE models) and how they are trained. In the fast-evolving world of Large Language Models (LLMs), different model types serve different performance and deployment goals…
The large language model (LLM) landscape is rapidly evolving, and two powerful contenders—DeepSeek and ChatGPT—are emerging as core engines in generative AI applications. While they both excel at generating human-like text, answering questions, and powering chatbots, they differ significantly in architecture, training objectives, inference capabilities, and deployment paradigms. Not long ago, I had my first…
