Term	Meaning
Organization	The top-level account boundary — your company or personal space on the grid. Members, teams, projects and wallets each belong to exactly one organization. (API payloads call it a `tenant`.)
Team	A group of members inside an organization that owns projects. Team membership alone grants no project rights.
Project	The unit that consumes and pays. It holds the wallet, the product assignments, the API keys and the sandbox products; every call names one.
Personal workspace	The organization provisioned automatically on your first sign-in, with a managed team, a managed project and a wallet — no setup required.
Project Wallet	The money attached to one project. Every call reserves and settles against it, and a project without funds cannot call a paid product.
Top-up	An organization Owner adding funds to a project wallet.
Micro-USD	The ledger unit: one millionth of a US dollar. Every price, hold and charge is integer micro-USD.
Reservation	The hold placed on the project wallet when a call is admitted, covering the call's maximum possible cost.
Settlement	Once the provider answers, the actual metered cost is charged against the reservation.
Release	The unused part of a reservation returned to the available balance — in full when a call is refused before reaching a provider.
Product	A model or media capability defined by the platform and offered for consumption at a frozen price.
Product version	The immutable published snapshot of a product — provider, model and price never change once published.
Deployment	The reviewed, published form of a product: immutable, priced, and the thing an assignment refers to.
Assignment	Binding an exact published product version to a project. Without one the project cannot invoke the product; removing one refuses new calls immediately.
Invocation policy	An Owner-managed named restriction — model allowlist, daily/monthly spending ceilings, an output-token cap, guardrail packs — scoped to an organization or one project. Every applicable policy stays in force at once.
Guardrail pack	PII, secret and prompt-injection screening composed into an invocation policy at observe, mask or block strength. A block happens before any money is reserved.
API key	A project-bound bearer credential (`aig_…`) for the `/v1` API. One key belongs to exactly one project, is revealed once at creation, and can carry its own model list, spending limit and expiry.
Playground	The in-console chat surface. It uses your signed-in session instead of a key, but shares the API's admission, reservation and settlement path — real calls, real charges.
Sandbox product	A project-private flow built in the studio from typed nodes, callable only by its owning project. It never appears in any catalogue.
Revision	An immutable saved state of a sandbox product's graph and contract. Activating a revision deploys it; a saved revision never changes.
