​
Overview

This endpoint stops a running fine-tune job. Stopping a job allows it to finalize gracefully — the most recent checkpoint is preserved and any in-progress evaluation is finished — and the job ends in the STOPPED state. To abandon a job without finalizing, use Cancel Job instead.

​
Path Parameters

​
job_id
string
required
Identifier of the job to stop (1–64 characters)

​
Response

Returns the updated job record. The job’s status will transition to STOPPING and then to STOPPED once the runner finishes finalizing.
​
status
string
Status of the job after the stop request. Typically STOPPING or STOPPED.
​
updated_at
string
ISO 8601 timestamp of the status change
