There's a new course in the Premium classroom called Build AI Systems: From Model Design to Custom PC. It has six video lessons, each with a full written walkthrough underneath, and it follows the whole path from how a model gets designed to the machine it runs on. The first two lessons are the software side. You'll see how a model is put together for a real job (collecting examples, holding back a test set, and choosing between prompting, RAG and fine-tuning), then how to wire an automated workflow with a trigger, an LLM call, logging, retries and a spending cap. The other four are hardware. Lesson 3 explains why VRAM decides which models you can run, using the actual Ollama download sizes for Qwen 3.5, Gemma 4 and gpt-oss. Lesson 4 is two AI workstation parts lists priced for late September 2026. Prices are rough right now because memory makers are prioritizing AI data center orders (a 32 GB DDR5 kit is running about $400 to $560), so the lesson also shows where you can save money and what each swap gives up. Lesson 5 walks through building a regular office or gaming PC step by step, and lesson 6 covers first boot, stress testing, installing Ollama and measuring tokens per second on your own machine. It's aimed at members who use ChatGPT or Claude and want to know what's happening underneath, and at anyone who's pricing a PC for local AI or getting ready to build their first computer.
