At present, we’re asserting the supply of AI21 Labs’ highly effective new Jamba 1.5 household of enormous language fashions (LLMs) in Amazon Bedrock. These fashions characterize a major development in long-context language capabilities, delivering pace, effectivity, and efficiency throughout a variety of functions. The Jamba 1.5 household of fashions consists of Jamba 1.5 Mini and Jamba 1.5 Giant. Each fashions assist a 256K token context window, structured JSON output, perform calling, and are able to digesting doc objects.

AI21 Labs is a frontrunner in constructing basis fashions and synthetic intelligence (AI) techniques for the enterprise. Collectively, AI21 Labs and AWS are empowering prospects throughout industries to construct, deploy, and scale generative AI functions that remedy real-world challenges and spark innovation by way of a strategic collaboration. With AI21 Labs’ superior, production-ready fashions along with Amazon’s devoted providers and highly effective infrastructure, prospects can leverage LLMs in a safe atmosphere to form the way forward for how we course of info, talk, and be taught.

What’s Jamba 1.5?
Jamba 1.5 fashions leverage a singular hybrid structure that mixes the transformer mannequin structure with Structured State Space model (SSM) expertise. This modern strategy permits Jamba 1.5 fashions to deal with lengthy context home windows as much as 256K tokens, whereas sustaining the high-performance traits of conventional transformer fashions. You’ll be able to be taught extra about this hybrid SSM/transformer structure within the Jamba: A Hybrid Transformer-Mamba Language Model whitepaper.

Now you can use two new Jamba 1.5 fashions from AI21 in Amazon Bedrock:

  • Jamba 1.5 Giant excels at advanced reasoning duties throughout all immediate lengths, making it very best for functions that require prime quality outputs on each lengthy and quick inputs.
  • Jamba 1.5 Mini is optimized for low-latency processing of lengthy prompts, enabling quick evaluation of prolonged paperwork and information.

Key strengths of the Jamba 1.5 fashions embrace:

  • Lengthy context dealing with – With 256K token context size, Jamba 1.5 fashions can enhance the standard of enterprise functions, akin to prolonged doc summarization and evaluation, in addition to agentic and RAG workflows.
  • Multilingual – Help for English, Spanish, French, Portuguese, Italian, Dutch, German, Arabic, and Hebrew.
  • Developer-friendly – Native assist for structured JSON output, perform calling, and able to digesting doc objects.
  • Pace and effectivity – AI21 measured the efficiency of Jamba 1.5 fashions and shared that the fashions show as much as 2.5X quicker inference on lengthy contexts than different fashions of comparable sizes. For detailed efficiency outcomes, go to the Jamba model family announcement on the AI21 website.

Get began with Jamba 1.5 fashions in Amazon Bedrock
To get began with the brand new Jamba 1.5 fashions, go to the Amazon Bedrock console, select Mannequin entry on the underside left pane, and request entry to Jamba 1.5 Mini or Jamba 1.5 Giant.

By selecting View API request, you will get a code instance of easy methods to invoke the mannequin utilizing the AWS Command Line Interface (AWS CLI) with the present instance immediate.

You’ll be able to comply with the code examples within the Amazon Bedrock documentation to entry out there fashions utilizing AWS SDKs and to construct your functions utilizing numerous programming languages.

The next Python code instance exhibits easy methods to ship a textual content message to Jamba 1.5 fashions utilizing the Amazon Bedrock Converse API for textual content technology.

import boto3
from botocore.exceptions import ClientError

# Create a Bedrock Runtime consumer.
bedrock_runtime = boto3.consumer("bedrock-runtime", region_name="us-east-1")

# Set the mannequin ID.
# modelId = "ai21.jamba-1-5-mini-v1:0"
model_id = "ai21.jamba-1-5-large-v1:0"

# Begin a dialog with the person message.
user_message = "What are 3 enjoyable details about mambas?"
dialog = [
    
        "role": "user",
        "content": ["text": user_message],
    
]

strive:
    # Ship the message to the mannequin, utilizing a fundamental inference configuration.
    response = bedrock_runtime.converse(
        modelId=model_id,
        messages=dialog,
        inferenceConfig="maxTokens": 256, "temperature": 0.7, "topP": 0.8,
    )

    # Extract and print the response textual content.
    response_text = response["output"]["message"]["content"][0]["text"]
    print(response_text)

besides (ClientError, Exception) as e:
    print(f"ERROR: Cannot invoke 'model_id'. Motive: e")
    exit(1)

The Jamba 1.5 fashions are good to be used instances like paired doc evaluation, compliance evaluation, and query answering for lengthy paperwork. They will simply evaluate info throughout a number of sources, test if passages meet particular tips, and deal with very lengthy or advanced paperwork. You’ll find instance code within the AI21-on-AWS GitHub repo. To be taught extra about easy methods to immediate Jamba fashions successfully, take a look at AI21’s documentation.

Now out there
AI21 Labs’ Jamba 1.5 household of fashions is mostly out there right now in Amazon Bedrock within the US East (N. Virginia) AWS Area. Examine the total Area listing for future updates. To be taught extra, take a look at the AI21 Labs in Amazon Bedrock product web page and pricing web page.

Give Jamba 1.5 fashions a strive within the Amazon Bedrock console right now and ship suggestions to AWS re:Post for Amazon Bedrock or by way of your traditional AWS Help contacts.
