The truss loops command provides subcommands for the Loops deployment lifecycle: pushing a deployment for a base model, viewing runs and samplers, and listing or deploying checkpoints from a run.
truss loops [OPTIONS] COMMAND [ARGS]...
CommandDescription
pushProvision a session, run, and sampler for a base model.
deactivateShut down the active deployment for a base model.
viewList active Loops deployments.
runs viewList Loops runs.
samplers viewList Loops samplers.
checkpoints viewList checkpoints for a Loops run.
checkpoints deployDeploy checkpoints from a Loops run.

push

Provision a Loops session, run, and paired sampler for a base model. If the project already has an active Loops deployment for the base model, the command fails with a validation error.
truss loops push [OPTIONS] BASE_MODEL

Arguments

BASE_MODEL
TEXT
required
Hugging Face model ID for the base model (for example, Qwen/Qwen3-8B).

Options

}
--project-id
TEXT
Training project ID to associate the deployment with.
--remote
TEXT
Name of the remote in .trussrc to deploy to.
--log
humanfriendly | W | WARNING | I | INFO | D | DEBUG
default:"humanfriendly"
Logging verbosity. humanfriendly (default) is pretty-printed; INFO, DEBUG, WARNING produce structured logs.
--non-interactive
Disable interactive prompts. Use in CI/automated contexts where stdin isn’t a TTY.
Example:
truss loops push Qwen/Qwen3-8B

deactivate

Shut down the active Loops deployment for a base model. Saved checkpoints remain accessible after deactivation.
truss loops deactivate [OPTIONS] BASE_MODEL

Arguments

BASE_MODEL
TEXT
required
Hugging Face model ID of the deployment to shut down.

Options

}
--remote
TEXT
Name of the remote in .trussrc.
-y, --yes
Skip the confirmation prompt.
--log
humanfriendly | W | WARNING | I | INFO | D | DEBUG
default:"humanfriendly"
Logging verbosity. humanfriendly (default) is pretty-printed; INFO, DEBUG, WARNING produce structured logs.
--non-interactive
Disable interactive prompts. Use in CI/automated contexts where stdin isn’t a TTY.
Example:
truss loops deactivate Qwen/Qwen3-8B --yes

view

List the caller’s active Loops deployments. Deployments whose latest status is STOPPED are filtered out server-side.
truss loops view [OPTIONS]

Options

}
--remote
TEXT
Name of the remote in .trussrc.
--log
humanfriendly | W | WARNING | I | INFO | D | DEBUG
default:"humanfriendly"
Logging verbosity. humanfriendly (default) is pretty-printed; INFO, DEBUG, WARNING produce structured logs.
--non-interactive
Disable interactive prompts. Use in CI/automated contexts where stdin isn’t a TTY.
Example:
truss loops view
The command prints a table with the deployment ID, base model, base URL, and deployment URL.

runs view

List Loops runs visible to the caller. Both filters are optional and can be combined; omit both to list every run.
truss loops runs view [OPTIONS]

Options

}
--run-id
TEXT
Filter to a specific run ID.
--base-model
TEXT
Filter runs by base model name.
-r, --reverse
Reverse the default order (oldest first) so the most recent run is shown first.
--remote
TEXT
Name of the remote in .trussrc.
--log
humanfriendly | W | WARNING | I | INFO | D | DEBUG
default:"humanfriendly"
Logging verbosity. humanfriendly (default) is pretty-printed; INFO, DEBUG, WARNING produce structured logs.
--non-interactive
Disable interactive prompts. Use in CI/automated contexts where stdin isn’t a TTY.
Example: List the most recent runs for a base model:
truss loops runs view --base-model Qwen/Qwen3-8B --reverse

samplers view

List Loops samplers visible to the caller.
truss loops samplers view [OPTIONS]

Options

}
-r, --reverse
Reverse the default order (oldest first) so the most recent sampler is shown first.
--remote
TEXT
Name of the remote in .trussrc.
--log
humanfriendly | W | WARNING | I | INFO | D | DEBUG
default:"humanfriendly"
Logging verbosity. humanfriendly (default) is pretty-printed; INFO, DEBUG, WARNING produce structured logs.
--non-interactive
Disable interactive prompts. Use in CI/automated contexts where stdin isn’t a TTY.
Example:
truss loops samplers view --reverse

checkpoints view

List checkpoints for a Loops run. Identify the run with --run-id, or pass --base-model to pick the most recent run for that base model. The two filters are mutually exclusive.
truss loops checkpoints view [OPTIONS]

Options

}
--run-id
TEXT
Loops run ID to list checkpoints for. Mutually exclusive with --base-model.
--base-model
TEXT
Base model name. Resolves to the most recent Loops run for that model. Mutually exclusive with --run-id.
--sort
checkpoint-id | size | created | type
default:"created"
Sort checkpoints by checkpoint ID, creation time, size, or type.
--order
asc | desc
default:"asc"
Sort order.
-o, --output-format
cli-table | csv | json
default:"cli-table"
Output format.
--remote
TEXT
Name of the remote in .trussrc.
--log
humanfriendly | W | WARNING | I | INFO | D | DEBUG
default:"humanfriendly"
Logging verbosity. humanfriendly (default) is pretty-printed; INFO, DEBUG, WARNING produce structured logs.
--non-interactive
Disable interactive prompts. Use in CI/automated contexts where stdin isn’t a TTY.
Examples: List checkpoints for the most recent run of a base model:
truss loops checkpoints view --base-model Qwen/Qwen3-8B
Get the largest checkpoints first, as JSON:
truss loops checkpoints view --run-id <run_id> --sort size --order desc -o json

checkpoints deploy

Deploy checkpoints from a Loops run as a vLLM-backed inference deployment. You must pass one of --run-id, --checkpoint-ids, or --config.
truss loops checkpoints deploy [OPTIONS]

Options

}
--run-id
TEXT
Loops run ID. Opens an interactive picker so you can choose checkpoints from the run. Cannot be combined with --checkpoint-ids.
--checkpoint-ids
TEXT
Comma-separated Loops checkpoint IDs (for example, vL3pQrS8,wK4tUvW9). Bypasses the interactive picker. Use truss loops checkpoints view to find IDs. Cannot be combined with --run-id or --config.
--config
TEXT
Path to a Python file that defines a DeployCheckpointsConfig. The config must populate checkpoint_details.loops_checkpoint_ids. Cannot be combined with --checkpoint-ids.
--dry-run
Render the generated truss config to stdout without deploying.

--log
humanfriendly | W | WARNING | I | INFO | D | DEBUG

truss loops checkpoints deploy --checkpoint-ids vL3pQrS8,wK4tUvW9
Render the generated config without deploying:
truss loops checkpoints deploy --run-id <run_id> --dry-run
