The setup runs a Qwen2.5:7b model requiring 6-7 GB vRAM, and the author recommends starting with a small vault to manage processing time and costs.", "body_md": "I’ve kept 330+ notes for years. Two years ago, I migrated from **Evernote** to **Obsidian** to build my own wiki/ knowledge base from multi-year saved documents. Not only technical ones, but any personal interests — how to fly DCS, riding motorcycles in mountains, photograph techniques — in both English and Chinese.\n\nI can query and chat with my wiki, pulling related topics across all my notes. Amazing, isn’t it?\n\nFound **Karpathy LLM Wiki** and got interested. It’s simpler than your expectation:\n\nThere are tons of tutorials about how it works and its **architecture**/ **workflow**. I recommend:\n\nI won’t repeat them. There are complex variants, but I tried several and burned tokens for days — this is the simplest approach.\n\nI have a GPD Win4 gamepad with internal and external AMD GPUs. I wanted to test its limits running a local LLM — speed and summarization quality.\n\nSelect a vault to start with. Start with a new vault and a few documents — LLM processing really takes time and costs money if using a public API.\n\nInstall Karpathy LLM Wiki plugin through community plugin.\n\nDon’t install any other plugin yet — you won’t know which is which.\n\nConnecting to a public LLM is simpler, but I burned $10/ day for 3 days and switched to local.\n\nAs long as ollama service is up, download a model. For instance:\n\n```\nollama run qwen2.5:7b\n```\n\nModel size depends on your hardware’s vRAM capacity. The one I’m using requires around 6~ 7 GB vRAM. Google’s Gemma 4 would work too.\n\nObsidian settings > Community plugins > Options (gear icon) of Karpathy LLM Wiki >\n\nOnce set up, ingest (copy/ move) your files into the raw/ folder. Press Ctrl + P > Karpathy LLM Wiki ingest from folder > select raw/ folder.\n\nYou should see GPU1 usage spike like the bottom-right screenshot above. The top-right is Graph View of my wiki built from 330+ documents — looks impressive.\n\nI’ve used **Arch Linux** for years, only kept Windows for gaming. Ditched it completely when Proton made Windows games run on Linux without performance penalty. **Arch Linux** can do almost everything I need — it’s now my only OS for work + leisure.\n\nbtw, I use **Arch**\n\n[Build Your Own AI-Powered Wiki with Obsidian + Karpathy LLM Wiki + Ollama](https://blog.devgenius.io/build-your-own-ai-powered-wiki-with-obsidian-karpathy-llm-wiki-ollama-beba1cbbd2bc) was originally published in [Dev Genius](https://blog.devgenius.io) on Medium, where people are continuing the conversation by highlighting and responding to this story.", "url": "https://wpnews.pro/news/build-your-own-ai-powered-wiki-with-obsidian-karpathy-llm-wiki-ollama", "canonical_source": "https://blog.devgenius.io/build-your-own-ai-powered-wiki-with-obsidian-karpathy-llm-wiki-ollama-beba1cbbd2bc?source=rss----4e2c1156667e---4", "published_at": "2026-08-05 09:08:23+00:00", "updated_at": "2026-08-05 09:30:39.436655+00:00", "lang": "en", "topics": ["artificial-intelligence", "large-language-models", "ai-tools", "ai-infrastructure"], "entities": ["Obsidian", "Karpathy LLM Wiki", "Ollama", "Qwen2.5:7b", "Evernote", "Arch Linux", "GPD Win4", "Dev Genius"], "alternates": {"html": "https://wpnews.pro/news/build-your-own-ai-powered-wiki-with-obsidian-karpathy-llm-wiki-ollama", "markdown": "https://wpnews.pro/news/build-your-own-ai-powered-wiki-with-obsidian-karpathy-llm-wiki-ollama.md", "text": "https://wpnews.pro/news/build-your-own-ai-powered-wiki-with-obsidian-karpathy-llm-wiki-ollama.txt", "jsonld": "https://wpnews.pro/news/build-your-own-ai-powered-wiki-with-obsidian-karpathy-llm-wiki-ollama.jsonld"}}
