PAI Dynamics Hosted — PhysicsCode's default free model.

PAI Dynamics Hosted is PhysicsCode’s built-in, no-setup model provider. Log in with your PhysicsCode account and start using it — no separate API key, no signup beyond your PhysicsCode login, and no cost by default.

How it works

Run physicscode account login (or /connect in the TUI and select PAI Dynamics Hosted).
That’s it. paidynamics is the default provider — you don’t need to pick a model to get started.

Run /models paidynamics (or physicscode models paidynamics) to see what’s currently being served. PhysicsCode discovers the model list live from the hosting server, so this reflects whatever checkpoint is actually running — it’s not a fixed, hardcoded list.

Pricing

Usage is billed against your PhysicsCode account credit. The per-token rate is set by the server operator (PAI_INPUT_USD_PER_MILLION / PAI_OUTPUT_USD_PER_MILLION in the Worker config) and defaults to free. Check your balance and usage history in the account portal’s Billing tab.

Bring your own key

PAI Dynamics Hosted is optional — you can configure any other provider (OpenAI, Anthropic, or a custom endpoint) instead, or alongside it. See Providers for the full list.
