aex runs autonomous agents on the hosted managed runtime. The SDK opens durable sessions, sends turns, streams events, captures outputs, and exposes auth-gated reads and downloads.
For what the product supports, see Features. For the current provider/model set, see the generated provider/runtime capability matrix.
Current Defaults
| Area | Default |
|---|---|
| Workspace storage | 500 GB per workspace for captured outputs and workspace artifacts. aex-maintainer admin workspaces may be unlimited for internal dogfooding; this is not a customer entitlement. |
Product Boundaries
| Area | Boundary |
|---|---|
| Runtime | New submissions run on the managed runtime. The runtime option selects a managed machine-size preset (Sizes.*); there is no alternative runtime backend. |
| Provider policy | Provider retention, training exclusion, HIPAA/BAA, data residency, abuse policy, and pricing belong to the selected provider account, endpoint, and contract. |
| Secrets | Provider keys, MCP credentials, and env secrets are caller-owned. aex excludes secret values from idempotency and uses the explicit secret surfaces described in Secrets. |
| MCP servers | Remote MCP servers are customer-trusted systems. aex validates declarations and routes credentials; it does not make an untrusted MCP server safe. |
| Outputs | Captured outputs, events, and metadata are stored under the run record and downloaded through auth-gated routes. Output content is customer content. |
| Human review | Runs execute after submission. Cancellation is available, but aex does not pause a run for platform-mediated approval or interactive clarification. |
| Sessions | The durable product primitive is the session/run record. Sessions can be resumed by id and auto-suspend after the configured idle window; persistent named agent profiles and saved agent definitions are out of scope. |
| Deployment | The supported product is the hosted aex service plus the SDK and CLI. Alternate baseUrl values are for local, staging, or hosted aex API planes, not a self-host product promise. |
| Cost | BYOK provider-token charges accrue to the customer's provider account. aex records report-only telemetry for runtime and storage usage; free trials, billing-grade invoices, and public pricing documents are not shipped unless documented later. |
