- Constructor Detail
- Method Detail
  - model
```
 final FineTuningJobCreateParams.Model model()
```
    The name of the model to fine-tune. You can select one of the supported models.
  - trainingFile
```
 final String trainingFile()
```
    The ID of an uploaded file that contains training data.
    See upload file for how to upload a file.
    Your dataset must be formatted as a JSONL file. Additionally, you must upload your file with the purpose fine-tune.
    The contents of the file should differ depending on if the model uses the chat, completions format, or if the fine-tuning method uses the preference format.
    See the fine-tuning guide for more details.
  - hyperparameters
```
@Deprecated(message = "deprecated") final Optional<FineTuningJobCreateParams.Hyperparameters> hyperparameters()
```
    The hyperparameters used for the fine-tuning job. This value is now deprecated in favor of method, and should be passed in under the method parameter.
  - integrations
```
 final Optional<List<FineTuningJobCreateParams.Integration>> integrations()
```
    A list of integrations to enable for your fine-tuning job.
  - metadata
```
 final Optional<Metadata> metadata()
```
    Set of 16 key-value pairs that can be attached to an object. This can be useful for storing additional information about the object in a structured format, and querying for objects via API or the dashboard.
    Keys are strings with a maximum length of 64 characters. Values are strings with a maximum length of 512 characters.
  - method
```
 final Optional<FineTuningJobCreateParams.Method> method()
```
    The method used for fine-tuning.
  - seed
```
 final Optional<Long> seed()
```
    The seed controls the reproducibility of the job. Passing in the same seed and job parameters should produce the same results, but may differ in rare cases. If a seed is not specified, one will be generated for you.
  - suffix
```
 final Optional<String> suffix()
```
    A string of up to 64 characters that will be added to your fine-tuned model name.
    For example, a suffix of "custom-model-name" would produce a model name like ft:gpt-4o-mini:openai:custom-model-name:7p4lURel.
  - validationFile
```
 final Optional<String> validationFile()
```
    The ID of an uploaded file that contains validation data.
    If you provide this file, the data is used to generate validation metrics periodically during fine-tuning. These metrics can be viewed in the fine-tuning results file. The same data should not be present in both train and validation files.
    Your dataset must be formatted as a JSONL file. You must upload your file with the purpose fine-tune.
    See the fine-tuning guide for more details.
  - _model
```
 final JsonField<FineTuningJobCreateParams.Model> _model()
```
    The name of the model to fine-tune. You can select one of the supported models.
  - _trainingFile
```
 final JsonField<String> _trainingFile()
```
    The ID of an uploaded file that contains training data.
    See upload file for how to upload a file.
    Your dataset must be formatted as a JSONL file. Additionally, you must upload your file with the purpose fine-tune.
    The contents of the file should differ depending on if the model uses the chat, completions format, or if the fine-tuning method uses the preference format.

```
    A list of integrations to enable for your fine-tuning job.
  - _metadata
```
 final JsonField<Metadata> _metadata()
```
    Set of 16 key-value pairs that can be attached to an object. This can be useful for storing additional information about the object in a structured format, and querying for objects via API or the dashboard.
    Keys are strings with a maximum length of 64 characters. Values are strings with a maximum length of 512 characters.
  - _method
```
 final JsonField<FineTuningJobCreateParams.Method> _method()
```
    The method used for fine-tuning.
  - _seed
```
 final JsonField<Long> _seed()
```
    The seed controls the reproducibility of the job. Passing in the same seed and job parameters should produce the same results, but may differ in rare cases. If a seed is not specified, one will be generated for you.
  - _suffix
```
 final JsonField<String> _suffix()
```
    A string of up to 64 characters that will be added to your fine-tuned model name.
    For example, a suffix of "custom-model-name" would produce a model name like ft:gpt-4o-mini:openai:custom-model-name:7p4lURel.
