Why Is My Local LLM So Slow? Common Bottlenecks

Running large language models locally promises privacy, control, and independence from cloud services. The appeal is obvious—no API costs, no data leaving your infrastructure, and the freedom to experiment without limitations. But the excitement of setting up your first local LLM often crashes against a frustrating reality: the model is painfully slow. Responses that cloud … Read more

Best Open-Source LLMs Under 7B Parameters (Run Locally in 2026)

Two years ago, running a capable language model locally meant wrestling with clunky setups, waiting minutes for a single response, and settling for mediocre outputs. In 2026, that reality has flipped entirely. A well-quantized 7B model runs smoothly on a laptop GPU, generates responses in seconds, and produces quality that rivals models ten times its … Read more

How Agents Decide What Tool to Call

The promise of AI agents is autonomy—systems that reason about tasks, select appropriate tools, and execute multi-step workflows without constant human guidance. But watch an agent in action and you’ll often see baffling tool selection: calling a web search when a calculator would work, invoking database queries for information in recent conversation, or repeatedly choosing … Read more

Designing Local LLM Systems for Long-Running Tasks

Local LLM applications face unique challenges when tasks extend beyond simple queries and responses. Analyzing hundreds of documents, generating comprehensive reports, processing entire codebases, or conducting multi-hour research requires architectures fundamentally different from chat interfaces. These long-running tasks introduce concerns about reliability, progress tracking, resource management, and graceful failure handling that quick queries never encounter. … Read more

How Local LLM Apps Handle Concurrency and Scaling

Running large language models locally creates unique challenges that cloud-based APIs abstract away. When you call OpenAI’s API, their infrastructure handles thousands of concurrent requests across distributed servers. But when you’re running Llama or Mistral on your own hardware, every concurrent user competes for the same GPU, the same memory, and the same processing power. … Read more

Why Bigger LLMs Don’t Always Mean Better Results

The AI industry’s obsession with parameter counts creates a persistent myth: more parameters equal better performance. When GPT-4 launched with rumored trillions of parameters, it seemed to confirm this assumption. Yet practitioners deploying models in production repeatedly discover a counterintuitive truth—smaller models often deliver better results than their larger counterparts for real-world applications. This isn’t … Read more

When a 7B Model Beats a 13B Model

The assumption that larger language models always perform better is deeply ingrained in the AI community. More parameters mean more knowledge, better reasoning, and superior outputs—or so the conventional wisdom goes. Yet in practical deployments, 7B parameter models frequently outperform their 13B counterparts on real-world tasks. This isn’t a statistical anomaly or measurement error; it … Read more

Experiment Tracking for Local ML Projects

Machine learning experimentation generates chaos. You try different architectures, tune hyperparameters, test preprocessing techniques, and compare models—quickly losing track of what worked and why. Without systematic experiment tracking, you repeat failures, forget successful configurations, and struggle to reproduce results. This problem intensifies when working on local machines where cloud-based tracking platforms aren’t suitable or desired. … Read more
