Conditions

To make use of the batch inference function, be sure to have glad the next necessities:

Put together the info

Earlier than you provoke a batch inference job for name middle transcript summarization, it’s essential to correctly format and add your information. The enter information needs to be in JSONL format, with every line representing a single transcript for summarization.

Every line in your JSONL file ought to observe this construction:

{"recordId": "11 character alphanumeric string", "modelInput": {JSON physique}}

Right here, recordId is an 11-character alphanumeric string, working as a singular identifier for every entry. Should you omit this discipline, the batch inference job will routinely add it within the output.

The format of the modelInput JSON object ought to match the physique discipline for the mannequin that you just use within the InvokeModel request. For instance, when you’re utilizing Anthropic Claude 3 on Amazon Bedrock, it’s best to use the MessageAPI and your mannequin enter would possibly appear to be the next code:

{
"recordId": "CALL0000001", 
 "modelInput": {
     "anthropic_version": "bedrock-2023-05-31", 
     "max_tokens": 1024,
     "messages": [ { 
           "role": "user", 
           "content": [{"type":"text", "text":"Summarize the following call transcript: ...." ]} ],
      }
}

When making ready your information, have in mind the quotas for batch inference listed within the following desk.

Ensure your enter information adheres to those measurement limits and format necessities for optimum processing. In case your dataset exceeds these limits, contemplating splitting it into a number of batch jobs.

Begin the batch inference job

After you have got ready your batch inference information and saved it in Amazon S3, there are two major strategies to provoke a batch inference job: utilizing the Amazon Bedrock console or API.

1. Create an Amazon Bedrock consumer:

   import boto3
   bedrock = boto3.consumer(service_name="bedrock")

2. Configure the enter and output information:

   input_data_config = {
       "s3InputDataConfig": {
           "s3Uri": "s3://{bucket_name}/{input_prefix}/your_input_data.jsonl"
       }
   }
   output_data_config = {
       "s3OutputDataConfig": {
           "s3Uri": "s3://{bucket_name}/{output_prefix}/"
       }
   }

3. Begin the batch inference job:

   response = bedrock.create_model_invocation_job(
       roleArn="arn:aws:iam::{account_id}:function/{role_name}",
       modelId="model-of-your-choice",
       jobName="your-job-name",
       inputDataConfig=input_data_config,
       outputDataConfig=output_data_config
   )

4. Retrieve and monitor the job standing:

   job_arn = response.get('jobArn')
   standing = bedrock.get_model_invocation_job(jobIdentifier=job_arn)['status']
   print(f"Job standing: {standing}")

Exchange the placeholders {bucket_name}, {input_prefix}, {output_prefix}, {account_id}, {role_name}, your-job-name, and model-of-your-choice along with your precise values.

By utilizing the AWS SDK, you possibly can programmatically provoke and handle batch inference jobs, enabling seamless integration along with your current workflows and automation pipelines.

Gather and analyze the output

When your batch inference job is full, Amazon Bedrock creates a devoted folder within the specified S3 bucket, utilizing the job ID because the folder title. This folder accommodates a abstract of the batch inference job, together with the processed inference information in JSONL format.

You may entry the processed output by way of two handy strategies: on the Amazon S3 console or programmatically utilizing the AWS SDK.

Entry the output on the Amazon S3 console

To make use of the Amazon S3 console, full the next steps:

1. On the Amazon S3 console, select Buckets within the navigation pane.
2. Navigate to the bucket you specified because the output vacation spot on your batch inference job.
3. Inside the bucket, find the folder with the batch inference job ID.

Inside this folder, you’ll discover the processed information recordsdata, which you’ll browse or obtain as wanted.

Entry the output information utilizing the AWS SDK

Alternatively, you possibly can entry the processed information programmatically utilizing the AWS SDK. Within the following code instance, we present the output for the Anthropic Claude 3 mannequin. Should you used a special mannequin, replace the parameter values in response to the mannequin you used.

The output recordsdata include not solely the processed textual content, but additionally observability information and the parameters used for inference. The next is an instance in Python:

import boto3
import json

# Create an S3 consumer
s3 = boto3.consumer('s3')

# Set the S3 bucket title and prefix for the output recordsdata
bucket_name="your-bucket-name"
prefix = 'your-output-prefix'
filename="your-output-file.jsonl.out"

# Learn the JSON file from S3
object_key = f"{prefix}{filename}"
response = s3.get_object(Bucket=bucket_name, Key=object_key)
json_data = response['Body'].learn().decode('utf-8')

# Initialize an inventory
output_data = []

# Course of the JSON information. Exhibiting instance for Anthropic Claude 3 Mannequin (replace json keys as essential for a special fashions) 
for line in json_data.splitlines():
    information = json.masses(line)
    request_id = information['recordId']
    
    # Entry the processed textual content
    output_text = information['modelOutput']['content'][0]['text']
    
    # Entry observability information
    input_tokens = information['modelOutput']['usage']['input_tokens']
    output_tokens = information['modelOutput']['usage']['output_tokens']
    mannequin = information['modelOutput']['model']
    stop_reason = information['modelOutput']['stop_reason']
    
    # Entry inference parameters
    max_tokens = information['modelInput']['max_tokens']
    temperature = information['modelInput']['temperature']
    top_p = information['modelInput']['top_p']
    top_k = information['modelInput']['top_k']
    
    # Create a dictionary for the present file
    output_entry = {
        request_id: {
            'output_text': output_text,
            'observability': {
                'input_tokens': input_tokens,
                'output_tokens': output_tokens,
                'mannequin': mannequin,
                'stop_reason': stop_reason
            },
            'inference_params': {
                'max_tokens': max_tokens,
                'temperature': temperature,
                'top_p': top_p,
                'top_k': top_k
            }
        }
    }
    
    # Append the dictionary to the checklist
    output_data.append(output_entry)

On this instance utilizing the Anthropic Claude 3 mannequin, after we learn the output file from Amazon S3, we course of every line of the JSON information. We are able to entry the processed textual content utilizing information['modelOutput']['content'][0]['text'], the observability information corresponding to enter/output tokens, mannequin, and cease motive, and the inference parameters like max tokens, temperature, top-p, and top-k.

Within the output location specified on your batch inference job, you’ll discover a manifest.json.out file that gives a abstract of the processed data. This file consists of data corresponding to the overall variety of data processed, the variety of efficiently processed data, the variety of data with errors, and the overall enter and output token counts.

You may then course of this information as wanted, corresponding to integrating it into your current workflows, or performing additional evaluation.

Bear in mind to interchange your-bucket-name, your-output-prefix, and your-output-file.jsonl.out along with your precise values.

By utilizing the AWS SDK, you possibly can programmatically entry and work with the processed information, observability data, inference parameters, and the abstract data out of your batch inference jobs, enabling seamless integration along with your current workflows and information pipelines.
