Using Local LLMs for Private Document Search

by

Privacy concerns around sensitive documents have made local AI solutions increasingly attractive. Whether you’re managing confidential business documents, personal medical records, legal files, or proprietary research, sending this information to cloud-based AI services poses significant risks. Local large language models (LLMs) combined with vector databases offer a powerful alternative: private, secure document search that never … Read more

How to Reduce VRAM Usage When Running LLMs Locally

by

Running large language models (LLMs) on your own hardware offers privacy, control, and cost savings compared to cloud-based solutions. However, the primary bottleneck most users face is VRAM (Video Random Access Memory) limitations. Modern LLMs can require anywhere from 4GB to 80GB of VRAM, making them inaccessible to users with consumer-grade GPUs. Fortunately, several proven … Read more

Best Local LLM for RAG (Retrieval-Augmented Generation)

by

Retrieval-augmented generation has transformed how we build intelligent systems that work with knowledge bases. By combining document retrieval with language model generation, RAG enables AI to answer questions grounded in specific sources rather than relying solely on training data. When implementing RAG locally, choosing the right language model becomes critical—you need a model that follows … Read more

Running Multiple Local LLMs: Memory & Performance Optimization

by

The ability to run multiple local LLMs simultaneously unlocks powerful workflows that single-model setups cannot achieve. Imagine switching instantly between a coding specialist, a creative writing model, and a general conversation assistant without reloading—or running them concurrently for complex tasks requiring different expertise. Yet most guides focus on running a single model optimally, leaving users … Read more

Quantized LLMs Explained: Q4 vs Q8 vs FP16

by

Quantization has emerged as the breakthrough technique that makes running powerful language models on consumer hardware practical. Without quantization, a 7-billion parameter model would require 28GB of RAM at full precision—placing it beyond the reach of most users. With 4-bit quantization, that same model runs comfortably in 6GB, transforming accessibility completely. Yet despite its importance, … Read more

How to Serve Local LLMs as an API (FastAPI + Ollama)

by

Running large language models locally gives you privacy, control, and independence from cloud services. But to unlock the full potential of local LLMs, you need to expose them through a robust API that applications can consume reliably. Combining FastAPI—Python’s modern, high-performance web framework—with Ollama’s efficient LLM serving capabilities creates a production-ready API that rivals commercial … Read more

How to Run LLMs Locally on Mac (M1 / M2 / M3) – Complete Guide

by

The ability to run large language models (LLMs) on your own Mac has transformed from a distant dream into an accessible reality. Apple’s silicon chips—the M1, M2, and M3—have democratized AI development by bringing unprecedented performance and efficiency to consumer hardware. Whether you’re a developer experimenting with AI applications, a privacy-conscious user, or simply curious … Read more

Large Language Models vs Transformers

by

The terminology surrounding modern AI can be bewildering, with terms like “large language models,” “transformers,” “GPT,” and “neural networks” often used interchangeably or inconsistently across different contexts. Among the most common sources of confusion is the relationship between “large language models” (LLMs) and “transformers”—are they the same thing? Different things? Is one a subset of … Read more

LLM Training vs Fine-Tuning: Understanding the Critical Distinction

by

The rise of large language models has introduced practitioners to two fundamentally different processes for creating AI systems: training from scratch and fine-tuning pre-trained models. While both involve adjusting model parameters through gradient descent, the scale, purpose, cost, and outcomes differ so dramatically that they represent entirely different approaches to model development. Training builds a … Read more

Difference Between LLM Training and Inference

by

The lifecycle of a large language model splits into two fundamentally distinct phases: training and inference. While both involve passing data through neural networks, the computational demands, objectives, constraints, and optimization strategies differ so dramatically that they might as well be separate disciplines. Training is the expensive, time-intensive process of teaching a model to understand … Read more
