Common Data Leakage Patterns in Machine Learning

Your model achieves 98% accuracy during validation—far better than expected. You deploy to production and performance collapses to barely above random. This frustrating scenario plays out repeatedly across ML projects, and the culprit is usually data leakage: information from outside the training dataset inadvertently influencing the model in ways that don’t generalize. Data leakage is … Read more

How Many Tokens Per Second Is ‘Good’ for Local LLMs?

You’ve set up a local LLM and it’s generating at 15 tokens per second. Is that good? Should you be happy, or is your setup underperforming? Unlike cloud services where you simply accept whatever speed you get, local LLMs put performance optimization in your hands—but that requires knowing what benchmarks to target. The answer isn’t … Read more

Why Small LLMs Are Winning in Real-World Applications

The narrative around large language models has long fixated on size: bigger models, more parameters, greater capabilities. GPT-4’s 1.7 trillion parameters, Claude’s massive context windows, and ever-expanding frontier models dominate headlines. Yet in production environments where businesses deploy AI at scale, a counterintuitive trend emerges: smaller language models—those with 1B to 13B parameters—are winning where … Read more

ChatGPT vs Local LLMs: Complete Comparison

The rise of large language models has given users two distinct paths: cloud-based services like ChatGPT or locally-run models on your own hardware. This choice affects everything from privacy and costs to performance and capabilities. Understanding the fundamental differences between ChatGPT and local LLMs helps you make informed decisions about which approach suits your needs. … Read more

Practical Local LLM Workflows

Local large language models have evolved from experimental curiosities to practical productivity tools. Running LLMs on your own hardware offers privacy, control, and unlimited usage—but the real value emerges when you integrate them into actual workflows. Rather than treating local LLMs as mere chatbots, you can build automated pipelines that handle repetitive tasks, process information … Read more

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

State, Memory, and Tools in Agentic AI (Explained Simply)

Agentic AI systems represent a fascinating evolution in artificial intelligence—systems that don’t just respond to prompts but actively pursue goals, make decisions, and take actions to accomplish tasks. Unlike traditional AI models that simply map inputs to outputs, agents maintain awareness of their situation, remember past interactions, and use various capabilities to navigate complex, multi-step … Read more

Why Conda Environments Break (And How to Avoid It)

Your conda environment worked perfectly yesterday. Today, after what seemed like a simple package update, importing NumPy crashes Python with a segmentation fault. Or conda hangs indefinitely during dependency resolution, consuming 16GB of RAM before you kill it. Or the environment that took 45 minutes to create last week now refuses to install, claiming unsolvable … Read more
