AI21 Labs Jamba-Instruct model now available on Amazon Bedrock

We’re excited to announce the supply of Jamba-Instruct Massive Language Mannequin (LLM) in Amazon Bedrock. Constructed by AI21 Labs, Jamba-Instruct most notably helps 256,000 token context home windows, making it notably helpful for processing giant recordsdata and sophisticated Retrieval Augmentation Era (RAG) purposes.

What’s Jamba-Instruct

Jamba-Instruct is an instruction-tuned model of the Jamba base mannequin, beforehand open sourced by AI21 Labs, which mixes production-grade fashions, Structured State House (SSM) know-how and Transformer structure. By means of the SSM method, Jamba-Instruct is ready to obtain the most important context window size in its mannequin measurement class whereas nonetheless offering the efficiency provided by conventional transformer-based fashions. The efficiency of those fashions has been improved over the earlier era fashions of the AI21 (Jurassic-2 collection fashions). For extra details about the hybrid SSM/Transformer structure, see the Jamba: Hybrid Transformer-Mamba Language Mannequin white paper.

Get began with Jamba-Instruct

To begin utilizing the Jamba-Instruct mannequin in Amazon Bedrock, you first have to entry the mannequin.

1. On the Amazon Bedrock console, select mannequin entry Within the navigation pane.
2. select Modify mannequin entry permissions.
3. Choose the AI21 Labs mannequin you need to use and choose Subsequent.
4. select submit Request mannequin entry.

For extra info, see Mannequin Entry.

Subsequent, you’ll be able to take a look at the mannequin within the Amazon Bedrock Textual content or Chat playground.

Pattern use circumstances for Jamba-Instruct

Jamba-Instruct’s lengthy context size is especially appropriate for complicated Retrieval Enhanced Era (RAG) workloads or doubtlessly complicated file evaluation. For instance, it’s appropriate for detecting contradictions between completely different recordsdata or analyzing one file within the context of one other file. Listed below are pattern ideas for this use case:

You might be an knowledgeable analysis assistant; 
you might be to notice any contradictions between the primary doc and second doc offered: 

Doc 1: 
{the doc content material} 

Doc 2: 
{the doc content material} 

Contradictions:

You can too use Jamba for question enhancement, a method that transforms uncooked queries into associated queries to optimize RAG purposes. For instance:

You're a curious and novel researcher, 
who is extremely concerned with getting all of the related info on a particular matter. 
Given an unique question, you wish to generate as much as 10 associated queries. 
These queries needs to be grounded within the unique question, however however new:

Unique Question:
{Unique Question}

New Queries:

You can too use Jamba for normal LLM operations reminiscent of summarization and entity retrieval.

Directions for Jamba-Instruct might be discovered within the AI21 mannequin recordsdata. For extra details about Jamba-Instruct, together with associated benchmarks, see Constructed for the Enterprise: Introduction to the Jamba-Instruct Mannequin at AI21.

programmatic entry

You can too entry Jamba-Instruct via the API utilizing Amazon Bedrock and the AWS SDK for Python (Boto3). For set up and setup directions, see Fast Begin. Here’s a pattern code snippet:

import boto3
import json

bedrock = boto3.consumer(service_name="bedrock-runtime")

immediate = "INSERT YOUR PROMPT HERE"

physique = json.dumps({
    "messages":[{"role":"user","content":prompt}],
    "max_tokens": 256,
    "top_p": 0.8,
    "temperature": 0.7,
})

modelId = "ai21.jamba-instruct-v1:0"

settle for = "software/json"
contentType = "software/json"

response = bedrock.invoke_model(
    physique=physique,
    modelId=modelId,
    settle for=settle for,
    contentType=contentType
)
consequence=json.hundreds(response.get('physique').learn())
print(consequence['choices'][0]['message']['content'])

in conclusion

AI2I Labs Jamba-Instruct in Amazon Bedrock is right for purposes that require lengthy context home windows (as much as 256,000 tokens), reminiscent of producing summaries or answering lengthy document-based questions, eliminating the necessity to manually phase doc sections. It’s appropriate for different LL.M. Smaller background window. The brand new SSM/Transformer hybrid structure additionally supplies mannequin throughput benefits. It supplies as much as 3 times the efficiency enchancment per second for context window lengths of over 128,000 tokens in comparison with different fashions in the same measurement class.

AI2I Labs Jamba-Instruct in Amazon Bedrock is offered within the US East (N. Virginia) AWS Area and is offered via an on-demand utilization mannequin. To study extra, see Base fashions supported in Amazon Bedrock. To get began utilizing AI2I Labs Jamba-Instruct with Amazon Bedrock, go to the Amazon Bedrock console.
