The Local AI Purity Test

A test for people who run open-weight models. Tick everything you've done and your score earns you a rank from Curious to Legend.

Take it at localaitest.com

How it works

There are 100 items. Your score is how many you ticked, so higher means more local.

Score	Rank
0–5	Curious
6–15	Enthusiast
16–30	Explorer
31–45	Regular
46–60	Builder
61–75	Quantizer
76–90	Power User
91–99	Legend
100	???

Every rank has its own animated card with a roast and a score of exactly 0 gets one too. Every score has its own share link (like /r/52-rich) and its link preview shows the rank's card.

Share on 𝕏 copies the card and opens a post or opens the share sheet on phones. Download video saves the animated card to attach instead.

Rig badge

Optionally add your hardware, either read from the hardware listed on your Hugging Face profile or picked by hand. Your total GPU or unified memory earns a badge:

Total memory	Badge
Under 16GB	GPU poor
16–47GB	VRAM middle class
48–191GB	GPU rich
192GB and up	Datacenter in a closet

Autofill

Connect GitHub or Hugging Face and the test ticks the items it can prove from your public profile. Each one is tagged "detected via…", so you can untick it.

• Hugging Face: your listed hardware (two 3090s, a 64GB or 512GB Mac, a DGX Spark or Strix Halo, two or more Sparks, four or more Sparks), uploaded models, GGUFs, LoRAs, merges and whether your downloads beat your followers
• GitHub: starring llama.cpp and opening issues or getting PRs merged in llama.cpp, Ollama or vLLM

The jokes

• A VRAM bar that fills as you tick items and overflows into "offloading to CPU… 0.4 tok/s"
• A GPU fan and temperature ("Your GPU: 68°C") that climb with your answers
• An "Ask an AI Assistant" button that runs out of CUDA memory
• Jokes on 37 items, shown when you hover over or tick them, including a deliberately bad pelican on a bicycle
• A hidden phrase: type gguf when anywhere on the page
• A 404 page that tells you to ollama pull it

Privacy

The site is run by Eigen Labs, Inc. The footer's privacy note is the user-facing version of this section; keep the two in sync.

• Your answers never leave your browser. They're saved on your device only (localStorage) and Reset deletes them.
• No accounts, no analytics and no tracking. The site's own code doesn't keep or log anything.
• The hosting provider (Vercel) receives standard request data, like IP addresses, to serve the page.
• Autofill is optional. The browser reads your public profile straight from GitHub's and Hugging Face's APIs.
  • Hugging Face login runs entirely in the browser, with PKCE. Its token can only read your basic profile and isn't cancelled afterward.
  • GitHub login asks for no permissions, so its token can only read public data. One server route swaps the login code for a token and hands it to the browser in the URL fragment, without storing or logging it. The browser asks GitHub to cancel the token when autofill finishes; if the page closes first, it isn't cancelled.
• Share links carry only your score and rig badge.

Stack

• Next.js 16 (App Router, Cache Components) with TypeScript and Tailwind CSS 4
• Rank cards are pre-made images and videos in public/cards and all 505 result pages are prerendered at build time
• The homepage preview card, favicon and logo are drawn with next/og
• Hosted on Vercel

public/cards/	Each rank's card, as a video and a still frame

Develop

npm install
npm run dev

Open http://localhost:3000.

npm test        # rank, rig and share-code unit tests
npm run build   # production build; prerenders all 505 result pages

Set NEXT_PUBLIC_SITE_URL to override the share-link domain (defaults to https://localaitest.com).

The Connect buttons need these environment variables, in .env.local locally and in your host's settings for production. Without them the buttons say they "aren't set up yet" and the rest of the test still works.

Variable	From
GITHUB_CLIENT_ID	A GitHub OAuth app whose callback is <site>/api/auth/github/callback
GITHUB_CLIENT_SECRET	The same GitHub OAuth app
NEXT_PUBLIC_HF_CLIENT_ID	A Hugging Face OAuth app with no secret, scopes openid profile and redirect <site>/
