llmster supplies LM Studio model serving without the desktop graphical application. Use lms to control the runtime, and keep the distinction between a daemon, a command line client, and a conversation interface explicit when planning a local headless workflow.

## The concrete application boundary

The names identify three responsibilities rather than three competing models. The LM Studio application supplies graphical interaction; llmster performs standalone background serving; lms controls either runtime from the terminal. The documented command set includes lms ls for available files, lms load for loading, and lms server start for the HTTP interface. These are different operations, so a model appearing in the file list is not evidence that a caller can already use it. A headless check should establish each transition explicitly. Also distinguish closing a client from stopping its runtime: the editor can disappear while another process still owns the loaded model and server ([LM Studio application guide](https://lmstudio.ai/docs/app)) ([LM Studio, llmster, and lms](https://lmstudio.ai/docs/app/basics/lmstudio-vs-llmster-vs-lms)).

## A practical route

Begin with a supported local machine and an identifiable model already available to the intended runtime. Inspect the model inventory through lms, load the required model, and start its local server. Connect a single local client. Keep notes about the process you started rather than assuming the last visible application window owns serving ([LM Studio developer documentation](https://lmstudio.ai/docs/developer)).

## A worked example

A workstation owner wants an editor to keep using local generation while the graphical model browser is absent. The useful check is to make an explanation request through that editor, inspect the actual runtime, and repeat after reopening the client. This is a personal process check, not a recipe for remote operation or a claim about automatic service management.

| Check | Record |
| --- | --- |
| Controller | lms is the command line tool used to inspect or control the runtime. |
| Runtime | llmster is the standalone daemon expected to perform local serving. |
| Consumer | The editor is the client that supplies source context and receives the generated explanation. |

## Reading the failure correctly

A missing GUI does not itself indicate a failure when llmster is the intended runtime. Conversely, a terminal command returning successfully does not prove that a later client request selected the correct model. Check the model inventory, server state, and caller separately before adding another process.

## What completes the check

Retain a restart note that names the runtime and the command line controller. Verify a fresh client conversation after restarting the local runtime under your normal workflow. Do not infer boot persistence or background lifetime from a single successful generation.
