Create a fine-tuning job

  • Python
  • NodeJS
  • OpenAI Python
  • OpenAI NodeJS
  • REST API
from portkey_ai import Portkey

# Initialize the Portkey client

portkey = Portkey(
api_key="PORTKEY_API_KEY", # Replace with your Portkey API key
virtual_key="VIRTUAL_KEY" # Add your provider's virtual key
)

fine_tune_job = portkey.fine_tuning.jobs.create(
    training_file="file_id", # encoded s3 file URI of the training data.
    model="model_id", # ex: modelId from bedrock for fine-tuning
    hyperparameters={
    "n_epochs": 1
    },
    role_arn="role_arn", # service role arn for bedrock job to assume when running.
    job_name="job_name", # name for the job, optional will created random if not provided.
    validation_file="file_id", # optional, must be encoded s3 file URI.
    suffix="finetuned_model_name",
    model_type="text" # optional, chat or text.
  )

print(fine_tune_job)
Notes:
  • Bedrock fine-tuning dataset format is a little bit different from OpenAI’s fine-tuning dataset format.
  • model_type field is required for the dataset transformation, currently gateway does the following dataset transformation:
    • chat -> text-to-text
    • chat -> chat.
  • model param should be the ModelID that is required for fine-tuning not for the inference. ModelID is different for inference and fine-tuning.
List of supported finetune models and their IDs are available at Bedrock documentation
