Create fine-tune

Creates a job that fine-tunes a specified model based on a given dataset. See this page for details.

create_fine_tune(
  training_file,
  validation_file = NULL,
  model,
  n_epochs = 4,
  batch_size = NULL,
  learning_rate_multiplier = NULL,
  prompt_loss_weight = 0.1,
  compute_classification_metrics = FALSE,
  classification_n_classes = NULL,
  classification_positive_class = NULL,
  classification_betas = NULL,
  suffix = NULL,
  openai_api_key = Sys.getenv("OPENAI_API_KEY"),
  openai_organization = NULL
)

Arguments

training_file

required; a length one character vector.

validation_file

optional; defaults to NULL; a length one character vector.

model

required; a length one character vector.

n_epochs

required; defaults to 4; a length one numeric vector with the integer value greater than 0.

batch_size

optional; defaults to NULL; a length one numeric vector with the integer value greater than 0.

learning_rate_multiplier

optional; defaults to NULL; a length one numeric vector with the value greater than 0.

prompt_loss_weight

required; defaults to 0.1; a length one numeric vector.

compute_classification_metrics

required; defaults to FLASE; a length one logical vector.

optional; defaults to NULL; a length one numeric vector with the value greater than 0.

classification_positive_class

optional; defaults to NULL; a length one character vector.

classification_betas

suffix

optional; defaults to NULL; a length one character vector.

openai_api_key

required; defaults to Sys.getenv("OPENAI_API_KEY") (i.e., the value is retrieved from the .Renviron file); a length one character vector. Specifies OpenAI API key.

openai_organization

optional; defaults to NULL; a length one character vector. Specifies OpenAI organization.

Value
