In the era of large language models (LLMs) like GPT-3 and Llama, fine-tuning these behemoths for specific tasks has become a cornerstone of AI development. However, traditional full fine-tuning demands enormous computational resources, often requiring hundreds of GBs of GPU memory and extensive training time. This is where parameter-efficient fine-tuning (PEFT) techniques shine, allowing us to adapt massive models with minimal overhead. Among these, Low-Rank Adaptation (LoRA) and its quantized variant, Quantized LoRA (QLoRA), stand out for their efficiency and effectiveness. In this technical blog, we’ll explore the mechanics, mathematics, advantages, and practical implementations of LoRA and QLoRA, drawing from foundational research and real-world applications.

Understanding Fine-Tuning Challenges

Full fine-tuning involves updating all parameters of a pre-trained model on a downstream dataset, which maximizes performance but at a steep cost. For instance, fine-tuning a 175B-parameter model like GPT-3 requires retraining every weight, leading to high memory usage and deployment challenges. PEFT methods mitigate this by updating only a subset of parameters or adding lightweight adapters, reducing trainable parameters by orders of magnitude while preserving model quality.

Data centers are the backbone of the digital economy, housing the servers, storage systems, and networking equipment that power cloud computing, web services, and data-intensive applications. In the United States, data centers are strategically located to meet the demands of businesses, governments, and consumers. The rise of artificial intelligence (AI) has further amplified the importance of data centers, requiring specialized infrastructure to handle complex computational workloads. This article explores the primary locations of data centers in the US, the reasons behind their selection, and recent developments driven by AI.

Major Data Center Locations in the United States

The US hosts approximately 5,381 data centers, with significant concentrations in specific regions that offer optimal conditions for operation. The top data center markets include:

The rapid expansion of artificial intelligence (AI), particularly large language models (LLMs) and generative AI, has driven an unprecedented surge in energy demand due to the computational intensity of training and operating these systems. Eric Schmidt, former Google CEO, has highlighted electricity as the primary limiter of AI growth, estimating that the U.S. will require an additional 92 gigawatts (GW) of power—equivalent to the output of 92 nuclear power plants—to sustain the AI revolution. This analysis explores the current energy consumption of major companies’ AI infrastructure, projects future energy needs through 2035, and examines how these demands will reshape the energy sector, drawing on available data from web sources and posts on X.

Current Energy Consumption by Major Companies

Overview

Major tech companies, or “hyperscalers” (e.g., Microsoft, Google, Meta, Amazon, OpenAI), are the primary drivers of AI infrastructure energy demand, operating massive data centers for training and inference of AI models. Training a single state-of-the-art AI model, such as OpenAI’s GPT-4, can consume 50 gigawatt-hours (GWh) of electricity, equivalent to the annual energy use of 4,800 U.S. households. Inference (running AI models for user queries) is also energy-intensive, with a single ChatGPT query requiring approximately 2.9 watt-hours, nearly 10 times that of a Google search (0.3 watt-hours). Below is an overview of key players’ energy footprints based on available data:

In the ever-evolving field of artificial intelligence, large language models (LLMs) like GPT-4, Claude, Gemini, and LLaMA have reshaped how machines understand and generate human language. Behind the impressive capabilities of these models lies a deceptively simple but foundational step: tokenization.

In this blog, we will dive deep into the concept of tokenization, understand its types, why it’s needed, the challenges it solves, how it works under the hood, and where it’s headed in the future. This is a one-stop technical deep-dive for anyone looking to fully grasp the backbone of language understanding in LLMs.

What is Tokenization?

At its core, tokenization is the process of converting raw text into smaller units called tokens that a language model can understand and process. These tokens can be:

• Characters
• Words
• Subwords
• Byte-pair sequences
• WordPieces
• SentencePieces
• Byte-level representations

Each model has its own strategy, depending on design goals like efficiency, vocabulary size, multilingual handling, and memory constraints.

BluSmart was once a symbol of India’s clean energy aspirations — an all-electric ride-hailing platform backed by marquee investors and government lenders. With its zero-emissions fleet and no-surge pricing model, it quickly gained popularity in cities like Delhi and Bengaluru.

But behind the scenes, the startup’s success story unraveled into one of the most serious corporate fraud cases in India’s startup ecosystem. At the center of this financial maze was Gensol Engineering Ltd, a publicly listed company, controlled by the same promoters behind BluSmart. The ₹262 crore scandal that emerged in 2025 now implicates not just BluSmart, but Gensol’s board, finances, and investors.
