Vetta Computer is where the agent does work: a disposable Linux micro-VM with a filesystem, shell, and optional browser, wired into the durable runtime. It pauses when the agent sleeps and resumes on the next turn — idle time costs storage, not compute.

Computer reference

Full detail on resources, lifecycle, filesystem, shell, browser, snapshots, volumes, networking, limits, and billing.

The micro-VM

A full Linux userland with configurable vCPU, memory, and disk — code, browser control, native binaries, daemons — paused between turns for near-zero idle cost.

Create a computer

Resources are optional — omit them and the computer provisions at the default 2 vCPU / 4 GiB. A small/medium/large preset is shorthand for a common combination.

What the agent can do

Inside a session, the agent reaches the computer through built-in tools:

Pause, resume, snapshot

A paused computer meters storage only and resumes with its filesystem intact. Computer lifecycle: create → running (metered per second) → paused (≈ storage only) → resume (disk intact), with snapshot and persistent-volume branches Snapshots and persistent volumes let state outlive a session. See the Computer reference.
Coming soon: a fully virtualized V8 isolate mode (mode: "isolate") with near-instant boot and near-zero idle, and vault secret injection on all sandbox egress (live on the MCP connector path today).

Fields

integer
default:"2"
Provisioned vCPU (1–16).
integer
default:"4096"
Provisioned memory in MiB (128–65536).
integer
Root disk size in whole GiB (up to 100).
boolean
default:"false"
Attach a managed browser; allowed_domains scopes what it may reach.
The full field list — presets, modes, volumes, snapshots — is in the Computer reference.

Next: identity
