Ollama handles concurrent requests but its default configuration is deliberately conservative — optimised for a single interactive user rather than multi-user production throughput. Understanding how Ollama manages parallelism, and how to tune it with OLLAMA_NUM_PARALLEL and related settings, is essential for anyone building applications that receive more than one request at a time. How Ollama … Read more
Kaggle Learn offers a set of short, free courses covering core data science and machine learning skills. Each course takes two to four hours, includes interactive coding exercises in Kaggle’s browser-based notebook environment, and awards a shareable completion certificate. For beginners looking to get hands-on ML experience quickly, and for practitioners who want to fill … Read more
Polars and NumPy are both Python libraries for working with numerical data, but they are designed for different tasks and different scales. NumPy is the foundation of scientific Python — a library for n-dimensional array operations that underpins pandas, scikit-learn, and most of the Python data science ecosystem. Polars is a modern DataFrame library built … Read more
A Modelfile is a simple configuration file that tells Ollama how to run a model — setting the system prompt, adjusting generation parameters like temperature and context window, and creating a named model variant you can reuse. If you have ever wanted to give a model a persistent persona, lower its temperature for coding tasks, … Read more
The Mac Studio is Apple’s most capable desktop for local LLM inference outside of the Mac Pro. With M4 Max (up to 128GB) or M4 Ultra (up to 192GB) unified memory options, it can run models that no other consumer or prosumer hardware can fit in a single machine — including 70B models comfortably and … Read more
Convolutional Neural Networks (CNNs) and Multi-Layer Perceptrons (MLPs) are both feedforward neural network architectures, but they are designed for fundamentally different kinds of data. Understanding when each architecture is appropriate — and why CNNs outperform MLPs on spatial data while MLPs remain competitive on tabular data — is essential for choosing the right model for … Read more
OLLAMA_HOST is the environment variable that controls which network address Ollama’s server listens on. By default Ollama binds only to localhost (127.0.0.1:11434), meaning only processes on the same machine can connect. Changing OLLAMA_HOST lets you make Ollama accessible to other devices on your local network, a Docker container, or any other host — which is … Read more
Ollama unloads models from memory after 5 minutes of inactivity by default. The next request after that timeout triggers a cold start — the model has to reload from disk before inference can begin, adding 5–30 seconds depending on model size and storage speed. The keep_alive setting is one of the most impactful Ollama configuration … Read more
Choosing a Mac for running local LLMs comes down to one number above everything else: unified memory. Unlike a Windows PC where the GPU has its own VRAM and the RAM is separate, Apple Silicon shares one memory pool between CPU and GPU. This means every gigabyte of RAM you buy is available to your … Read more
Continue is an open-source VS Code extension that connects your editor to any LLM — including local models running via Ollama — to give you AI-assisted coding that never sends your code to an external server. Where Cursor and GitHub Copilot route everything through cloud APIs, Continue lets you use Qwen2.5-Coder, Phi-4-mini, or any Ollama … Read more
