v1.4.0

Highlights

Volumes GA

The baseten volume commands are now considered stable for general use.

New commands

• baseten sandbox preview to expose a sandbox port on an HTTPS URL, public or token-gated.
• baseten volume tag set/delete and volume update to manage tags and volume expiration.
• baseten auth list to list stored profiles.
• baseten harness sync to reapply previous harness setup choices against the latest server routes.
• baseten harness harness-defaults (PRE-RELEASE) to show a team's default routes per harness.

Command updates

• Volume commands are now generally available, with bandwidth reporting on push/pull and concurrency flags on cat.
• baseten sandbox create/update accept lifecycle flags (--idle-ttl, --max-age, --expires-at, --terminated-retention).
• baseten sandbox image push accepts --memory and --volume to size the build environment.
• baseten sandbox connect reconnects after the connection drops, such as when an idle sandbox hibernates.
• baseten harness setup uses team default routes, requires --team with multiple teams, renames --route to --primary-route, and supports the OpenCode desktop app.
• baseten harness usage shows spend per team with a daily chart of the top models.
• Empty JSON lists print [] instead of null, and parent commands with shared required flags show help instead of failing.
