​
Overview

This endpoint cancels a fine-tune job in the authenticated organization. Cancellation terminates the job immediately without finalizing — no further checkpoints are written, and the job ends in the CANCELLED state. If you want the job to wind down gracefully and preserve its most recent checkpoint, use Stop Job instead.

​
Path Parameters

​
job_id

​
Response

​
status
string
Status of the job after the cancel request. Typically CANCELLED.
​
updated_at
string
ISO 8601 timestamp of the status change
