Start here · the whole loop
Get PWM first, then put it to work with AI4Science
Two minutes, three parts. First earn a starter balance of PWM right here on the website, then install the AI4Science agent and spend it — earning more back through feedback as you go. We'll use one real example the whole way through: the CASSI principle.
Our running example — the CASSI principle (L1-003)
Coded Aperture Snapshot Spectral Imaging is a Principle (Layer 1): a physics fingerprint for capturing a full hyperspectral cube in a single snapshot. Every step below acts on this one artifact, so you can follow along on its live page: /artifact/l1/L1-003 →
Get PWM first — on physicsworldmodel.org
PWM is earned by contributing, never sold. You bootstrap a starter balance here in the browser — no install needed.
Sign in (your wallet comes with it)
Sign in with Google/email — that gives you a non-custodial embedded wallet automatically (no seed phrase) — or connect your own wallet (MetaMask, Coinbase). Either way, one wallet = your identity + where PWM is credited.
Open the CASSI principle
Go to the CASSI principle page (or browse all principles at /principles). Read the artifact, then scroll to the Contribute panel at the bottom — it has two ways to earn.
Easiest: "Submit without uploading" — a free check
One click. It takes a faithful snapshot of the CASSI principle and runs it through the automated quality gate. On acceptance you're credited ≈ 0.5 PWM within ~1 minute — recorded against your wallet. Allowed once per layer (Principle / Digital Twin / Benchmark / Solution), up to a small daily cap. Nothing to write.
More: "Submit by uploading" a real improvement
Upload a genuine modification (a .md + .json) — e.g. a sharper CASSI forward model or a corrected noise spec. A full S1–S4 Claude review checks soundness; an accepted upload earns a larger one-time bootstrap (≈ 2 PWM). Creating a brand-new artifact earns more than modifying one.
Exact amounts are set by the protocol's emission equation (see the white paper) — earlier and harder contributions are worth more. Stage 1 is an off-chain balance credited to your wallet address; it settles on-chain at mainnet. See How to get PWM for the full detail.
Use AI4Science — spend PWM to do science
With a balance in hand, install the agent and put it to work. It runs like Claude Code, then specializes on PWM's verified artifacts. Full intro →
Install & log in
Needs only Python ≥ 3.10 — no git, no Node. Pick your OS, then log in with the same wallet that holds your PWM.
🐧 Linux / 🍎 macOS
curl -fsSL https://raw.githubusercontent.com/integritynoble/AI4Science/main/install.sh | bash🪟 Windows (PowerShell)
irm https://physicsworldmodel.org/install.ps1 | iex▶ Then, on any OS
ai4science loginOpen a new terminal after installing so ai4science is on your PATH. Not found? export PATH="$HOME/.local/bin:$PATH" (Linux/macOS).
Ask it about the CASSI principle
Start a session and work with the same artifact you just earned PWM on. Each agent turn spends a small amount of your PWM balance.

Earn PWM back — feedback inside AI4Science
Using the agent costs PWM; the easiest way to earn it back is feedback — right inside the chat session, no website round-trip.
Use the /feedback command
Spotted something about the CASSI workflow that should improve? Tell the agent — concrete, actionable feedback scores highest.
/feedback the CASSI judge should accept .h5 inputs too, not only .matGet rewarded instantly
An LLM judge scores your feedback's quality (0–1) and credits PWM to your balance on the spot — higher quality, higher reward. Low-effort or duplicate feedback scores zero, so it can't be farmed.
Or contribute tools & solutions — earn weekly
Beyond feedback, you can publish tools/sub-agents or submit solutions (e.g. a new CASSI reconstruction method). Whenever an agent uses them on a paid turn, you earn from the weekly emission pool — for as long as they stay useful. See how contributing earns PWM →
