DGX Spark

From Text to SQL: Fine-Tuning Phi-4-Mini-Instruct with LoRA and PyTorch (Deep Dive)

In this deep-dive video, I’ll walk through the full workflow of LoRA fine-tuning the Phi-4-Mini-Instruct model to improve natural-language-to-SQL accuracy. The demonstration runs on an NVIDIA DGX Spark, but the methods apply to any CUDA-based environment.

Running OpenAI’s GPT-OSS-20B Locally with Open WebUI (Full Setup Guide)

In this hands-on walkthrough, I’ll show you how to set up Open WebUI with OpenAI’s GPT-OSS-20B — a 20-billion-parameter open model — running locally inside Docker.

NVIDIA DGX Spark is the data-center AI lab that fits on your desk, but is it right for you?

I recently added a DGX Spark to my lab and have been putting it through its paces. In this video, I'll unpack what the DGX Spark actually is, why NVIDIA built it, and who it’s really for (and who it isn’t for).
