​
Authorization
string
header
required

Bearer authentication header of the form Bearer <token>, where <token> is your auth token.

Path Parameters

​
fine_tuning_job_id
string
required

The ID of the fine-tuning job.

Example:

"ft-AF1WoRqd3aJAHsqc9NY7iL8F"

Response

200 - application/json

OK

The fine_tuning.job object represents a fine-tuning job that has been created through the API.

​
id
string
required

The object identifier, which can be referenced in the API endpoints.

​
created_at
integer
required

The Unix timestamp (in seconds) for when the fine-tuning job was created.

​
error
object | null
required

For fine-tuning jobs that have failed, this will contain more information on the cause of the failure.

​
fine_tuned_model
string | null
required

The name of the fine-tuned model that is being created. The value will be null if the fine-tuning job is still running.

​
finished_at
integer | null
required

The Unix timestamp (in seconds) for when the fine-tuning job was finished. The value will be null if the fine-tuning job is still running.

​
hyperparameters
object
required

The hyperparameters used for the fine-tuning job. This value will only be returned when running supervised jobs.

​
model
string
required

The base model that is being fine-tuned.

​
object
enum<string>
required

The object type, which is always "fine_tuning.job".

Available options:
fine_tuning.job
​
organization_id
string
required

The organization that owns the fine-tuning job.

​
result_files
string[]
required

The compiled results file ID(s) for the fine-tuning job. You can retrieve the results with the Files API.

​
status
enum<string>
required

The current status of the fine-tuning job, which can be either validating_files, queued, running, succeeded, failed, or cancelled.

Available options:
validating_files,
queued,
running,
succeeded,
failed,
