Karpathy 把 AI 个性化的痛点说透了——Farzapedia 让用户掌控数据而非被 AI 公司锁定，适合注重隐私和自主性的开发者直接尝试。
Karpathy 在推文中推荐了 Farzapedia，一个基于个人维基百科的 AI 记忆系统。与主流 AI 的隐式记忆不同，Farzapedia 将用户数据以显式、可浏览的 Markdown 和图片文件形式存储在本地，用户可完全掌控。它支持 BYOAI（自带 AI），可接入 Claude、Codex 等任意模型，甚至可微调开源模型。Karpathy 认为这种“文件优先”的个性化方式让用户拥有数据主权，并强调掌握 AI 代理是 21 世纪核心技能。
Farzapedia, personal wikipedia of Farza, good exam…
Farzapedia, personal wikipedia of Farza, good example following my Wiki LLM tweet.
I really like this approach to personalization in a number of ways, compared to "status quo" of an AI that allegedly gets better the more you use it or something:
1. Explicit. The memory artifact is explicit and navigable (the wiki), you can see exactly what the AI does and does not know and you can inspect and manage this artifact, even if you don't do the direct text writing (the LLM does). The knowledge of you is not implicit and unknown, it's explicit and viewable. 2. Yours. Your data is yours, on your local computer, it's not in some particular AI provider's system without the ability to extract it. You're in control of your information. 3. File over app. The memory here is a simple collection of files in universal formats (images, markdown). This means the data is interoperable: you can use a very large collection of tools/CLIs or whatever you want over this information because it's just files. The agents can apply the entire Unix toolkit over them. They can natively read and understand them. Any kind of data can be imported into files as input, and any kind of interface can be used to view them as the output. E.g. you can use Obsidian to view them or vibe code something of your own. Search "File over app" for an article on this philosophy. 4. BYOAI. You can use whatever AI you want to "plug into" this information - Claude, Codex, OpenCode, whatever. You can even think about taking an open source AI and finetuning it on your wiki - in principle, this AI could "know" you in its weights, not just attend over your data.
So this approach to personalization puts *you* in full control. The data is yours. In Universal formats. Explicit and inspectable. Use whatever AI you want over it, keep the AI companies on their toes! :)
Certainly this is not the simplest way to get an AI to know you - it does require you to manage file directories and so on, but agents also make it quite simple and they can help you a lot. I imagine a number of products might come out to make this all easier, but imo "agent proficiency" is a CORE SKILL of the 21st century. These are extremely powerful tools - they speak English and they do all the computer stuff for you. Try this opportunity to play with one.
