On this part, we’ll present you learn how to fine-tune the Llama 3.2 3B Instruct mannequin utilizing SageMaker JumpStart. We’ll additionally share the supported occasion sorts and context for the Llama 3.2 fashions out there in SageMaker JumpStart. Though not highlighted on this submit, you may also discover different Llama 3.2 Mannequin variants that may be fine-tuned utilizing SageMaker JumpStart.

Instruction fine-tuning

The textual content technology mannequin might be instruction fine-tuned on any textual content knowledge, offered that the information is within the anticipated format. The instruction fine-tuned mannequin might be additional deployed for inference. The coaching knowledge should be formatted in a JSON Strains (.jsonl) format, the place every line is a dictionary representing a single knowledge pattern. All coaching knowledge should be in a single folder, however might be saved in a number of JSON Strains recordsdata. The coaching folder may comprise a template.json file describing the enter and output codecs.

Artificial dataset

For this use case, we’ll use a synthetically generated dataset named amazon10Ksynth.jsonl in an instruction-tuning format. This dataset accommodates roughly 200 entries designed for coaching and fine-tuning LLMs within the finance area.

The next is an instance of the information format:

instruction_sample = {
    "query": "What's Amazon's plan for increasing their bodily retailer footprint and the way will that influence their general income?",
    "context": "The ten-Okay report mentions that Amazon is constant to broaden their bodily retailer community, together with 611 North America shops and 32 Worldwide shops as of the tip of 2022. This bodily retailer enlargement is predicted to contribute to elevated product gross sales and general income progress.",
    "reply": "Amazon is increasing their bodily retailer footprint, with 611 North America shops and 32 Worldwide shops as of the tip of 2022. This bodily retailer enlargement is predicted to contribute to elevated product gross sales and general income progress."
}
 
print(instruction_sample)

Immediate template

Subsequent, we create a immediate template for utilizing the information in an instruction enter format for the coaching job (as a result of we’re instruction fine-tuning the mannequin on this instance), and for inferencing the deployed endpoint.

import json

prompt_template = {
  "immediate": "query: {query} context: {context}",
  "completion": "{reply}"
}

with open("prompt_template.json", "w") as f:
    json.dump(prompt_template, f)

After the immediate template is created, add the ready dataset that will probably be used for fine-tuning to Amazon S3.

from sagemaker.s3 import S3Uploader
import sagemaker
output_bucket = sagemaker.Session().default_bucket()
local_data_file = "amazon10Ksynth.jsonl"
train_data_location = f"s3://{output_bucket}/amazon10Ksynth_dataset"
S3Uploader.add(local_data_file, train_data_location)
S3Uploader.add("prompt_template.json", train_data_location)
print(f"Coaching knowledge: {train_data_location}")

Positive-tuning the Meta Llama 3.2 3B mannequin

Now, we’ll fine-tune the Llama 3.2 3B mannequin on the monetary dataset. The fine-tuning scripts are based mostly on the scripts offered by the Llama fine-tuning repository.

from sagemaker.jumpstart.estimator import JumpStartEstimator
 
estimator = JumpStartEstimator(
    model_id=model_id,
    model_version=model_version,
    surroundings={"accept_eula": "true"},
    disable_output_compression=True,
    instance_type="ml.g5.12xlarge",  
)
 
# Set the hyperparameters for instruction tuning
estimator.set_hyperparameters(
    instruction_tuned="True", epoch="5", max_input_length="1024"
)
 
# Match the mannequin on the coaching knowledge
estimator.match({"coaching": train_data_location})

Importing a customized mannequin from SageMaker to Amazon Bedrock

On this part, we’ll use a Python SDK to create a mannequin import job, get the imported mannequin ID and eventually generate inferences. You may consult with the console screenshots within the earlier part  for learn how to import a mannequin utilizing the Amazon Bedrock console.

Parameter and helper perform arrange

First, we’ll create a number of helper features and arrange our parameters to create the import job. The import job is chargeable for accumulating and deploying the mannequin from SageMaker to Amazon Bedrock. That is completed through the use of the create_model_import_job perform.

Saved safetensors have to be formatted in order that the Amazon S3 location is the top-level folder. The configuration recordsdata and safetensors will probably be saved as proven within the following determine.

import json
import boto3
from botocore.exceptions import ClientError
bedrock = boto3.shopper('bedrock', region_name="us-east-1")
job_name="fine-tuned-model-import-demo"
sagemaker_model_name="meta-textgeneration-llama-3-2-3b-2024-10-12-23-29-57-373"
model_url = {'s3DataSource':
                 {'s3Uri':
                      "s3://sagemaker-{REGION}-{AWS_ACCOUNT}/meta-textgeneration-llama-3-2-3b-2024-10-12-23-19-53-906/output/mannequin/"
                  }
             }

Test the standing and get job ARN from the response:

After a couple of minutes, the mannequin will probably be imported, and the standing of the job might be checked utilizing get_model_import_job. The job ARN is then used to get the imported mannequin ARN, which we’ll use to generate inferences.

def get_import_model_from_job(job_name):
    response = bedrock.get_model_import_job(jobIdentifier=job_name)
    return response['importedModelArn']


job_arn = response['jobArn']
import_model_arn = get_import_model_from_job(job_arn)

Producing inferences utilizing the imported customized mannequin

The mannequin might be invoked through the use of the invoke_model and converse APIs. The next is a assist perform that will probably be used to invoke and extract the generated textual content from the general output.

from botocore.exceptions import ClientError

shopper = boto3.shopper('bedrock-runtime', region_name="us-east-1")

def generate_conversation_with_imported_model(native_request, model_id):
    request = json.dumps(native_request)
    strive:
        # Invoke the mannequin with the request.
        response = shopper.invoke_model(modelId=model_id, physique=request)
        model_response = json.masses(response["body"].learn())

        response_text = model_response["outputs"][0]["text"]
        print(response_text)
    besides (ClientError, Exception) as e:
        print(f"ERROR: Cannot invoke '{model_id}'. Motive: {e}")
        exit(1)

Context arrange and mannequin response

Lastly, we are able to use the customized mannequin. First, we format our inquiry to match the fined-tuned immediate construction. This can make it possible for the responses generated carefully resemble the format used within the fine-tuning section and are extra aligned to our wants. To do that we use the template that we used to format the information used for fine-tuning. The context will probably be coming out of your RAG options like Amazon Bedrock Knowledgebases. For this instance, we take a pattern context and add to demo the idea:

input_output_demarkation_key = "nn### Response:n"
query = "Inform me what was the improved influx worth of money?"

context = "Amazons free money stream much less principal repayments of finance leases and financing obligations improved to an influx of $46.1 billion for the trailing twelve months, in contrast with an outflow of $10.1 billion for the trailing twelve months ended March 31, 2023."

payload = {
    "immediate": template[0]["prompt"].format(
                                    query=query, # person question
                                    context=context 
                                       + input_output_demarkation_key # rag context
                                        ),
    "max_tokens": 100, 
    "temperature": 0.01 
}
generate_conversation_with_imported_model(payload, import_model_arn)

The output will look much like:

After the mannequin has been fine-tuned and imported into Amazon Bedrock, you may experiment by sending totally different units of enter questions and context to the mannequin to generate a response, as proven within the following instance:

query: """How did Amazon's worldwide phase working earnings change 
            in This autumn 2022 in comparison with the prior 12 months?"""
context: """Amazon's worldwide phase reported an working lack of 
            $1.1 billion in This autumn 2022, an enchancment from a $1.7 billion 
            working loss in This autumn 2021."""
