The latest AI fashions from Meta, Llama 4 Scout 17B and Llama 4 Maverick 17B, are actually obtainable as a completely managed, serverless possibility in Amazon Bedrock. These new basis fashions (FMs) ship natively multimodal capabilities with early fusion expertise that you need to use for exact picture grounding and prolonged context processing in your functions.
Llama 4 makes use of an progressive mixture-of-experts (MoE) structure that gives enhanced efficiency throughout reasoning and picture understanding duties whereas optimizing for each price and velocity. This architectural strategy permits Llama 4 to supply improved efficiency at decrease price in comparison with Llama 3, with expanded language help for international functions.
The fashions had been already obtainable on Amazon SageMaker JumpStart, and now you can use them in Amazon Bedrock to streamline constructing and scaling generative AI functions with enterprise-grade safety and privateness.
Llama 4 Maverick 17B – A natively multimodal mannequin that includes 128 specialists and 400 billion complete parameters. It excels in picture and textual content understanding, making it appropriate for versatile assistant and chat functions. The mannequin helps a 1 million token context window, supplying you with the flexibleness to course of prolonged paperwork and sophisticated inputs.
Llama 4 Scout 17B – A general-purpose multimodal mannequin with 16 specialists, 17 billion lively parameters, and 109 billion complete parameters that delivers superior efficiency in comparison with all earlier Llama fashions. Amazon Bedrock at the moment helps a 3.5 million token context window for Llama 4 Scout, with plans to broaden within the close to future.
Use circumstances for Llama 4 fashions
You should utilize the superior capabilities of Llama 4 fashions for a variety of use circumstances throughout industries:
Enterprise functions – Construct clever brokers that may purpose throughout instruments and workflows, course of multimodal inputs, and ship high-quality responses for enterprise functions.
Multilingual assistants – Create chat functions that perceive photographs and supply high-quality responses throughout a number of languages, making them accessible to international audiences.
Code and doc intelligence – Develop functions that may perceive code, extract structured information from paperwork, and supply insightful evaluation throughout massive volumes of textual content and code.
Buyer help – Improve help methods with picture evaluation capabilities, enabling more practical downside decision when prospects share screenshots or pictures.
Content material creation – Generate artistic content material throughout a number of languages, with the power to know and reply to visible inputs.
Analysis – Construct analysis functions that may combine and analyze multimodal information, offering insights throughout textual content and pictures.
Utilizing Llama 4 fashions in Amazon Bedrock
To make use of these new serverless fashions in Amazon Bedrock, I first must request entry. Within the Amazon Bedrock console, I select Mannequin entry from the navigation pane to toggle entry to Llama 4 Maverick 17B and Llama 4 Scout 17B fashions.
The Llama 4 fashions might be simply built-in into your functions utilizing the Amazon Bedrock Converse API, which offers a unified interface for conversational AI interactions.
Right here’s an instance of how one can use the AWS SDK for Python (Boto3) with Llama 4 Maverick for a multimodal dialog:
import boto3 import json import os AWS_REGION = "us-west-2" MODEL_ID = "us.meta.llama4-maverick-17b-instruct-v1:0" IMAGE_PATH = "picture.jpg" def get_file_extension(filename: str) -> str: """Get the file extension.""" extension = os.path.splitext(filename)[1].decrease()[1:] or 'txt' if extension == 'jpg': extension = 'jpeg' return extension def read_file(file_path: str) -> bytes: """Learn a file in binary mode.""" attempt: with open(file_path, 'rb') as file: return file.learn() besides Exception as e: increase Exception(f"Error studying file {file_path}: {str(e)}") bedrock_runtime = boto3.consumer( service_name="bedrock-runtime", region_name=AWS_REGION ) request_body = { "messages": [ { "role": "user", "content": [ { "text": "What can you tell me about this image?" }, { "image": { "format": get_file_extension(IMAGE_PATH), "source": {"bytes": read_file(IMAGE_PATH)}, } }, ], } ] } response = bedrock_runtime.converse( modelId=MODEL_ID, messages=request_body["messages"] ) print(response["output"]["message"]["content"][-1]["text"])This instance demonstrates how one can ship each textual content and picture inputs to the mannequin and obtain a conversational response. The Converse API abstracts away the complexity of working with completely different mannequin enter codecs, offering a constant interface throughout fashions in Amazon Bedrock.
For extra interactive use circumstances, you can even use the streaming capabilities of the Converse API:
response_stream = bedrock_runtime.converse_stream( modelId=MODEL_ID, messages=request_body['messages'] ) stream = response_stream.get('stream') if stream: for occasion in stream: if 'messageStart' in occasion: print(f"nRole: {occasion['messageStart']['role']}") if 'contentBlockDelta' in occasion: print(occasion['contentBlockDelta']['delta']['text'], finish="") if 'messageStop' in occasion: print(f"nStop purpose: {occasion['messageStop']['stopReason']}") if 'metadata' in occasion: metadata = occasion['metadata'] if 'utilization' in metadata: print(f"Utilization: {json.dumps(metadata['usage'], indent=4)}") if 'metrics' in metadata: print(f"Metrics: {json.dumps(metadata['metrics'], indent=4)}") With streaming, your functions can present a extra responsive expertise by displaying mannequin outputs as they’re generated.
Issues to know
The Llama 4 fashions can be found immediately with a completely managed, serverless expertise in Amazon Bedrock within the US East (N. Virginia) and US West (Oregon) AWS Areas. You can even entry Llama 4 in US East (Ohio) through cross-region inference.
As standard with Amazon Bedrock, you pay for what you employ. For extra info, see Amazon Bedrock pricing.
These fashions help 12 languages for textual content (English, French, German, Hindi, Italian, Portuguese, Spanish, Thai, Arabic, Indonesian, Tagalog, and Vietnamese) and English when processing photographs.
To start out utilizing these new fashions immediately, go to the Meta Llama fashions part within the Amazon Bedrock Consumer Information. You can even discover how our Builder communities are utilizing Amazon Bedrock of their options within the generative AI part of our neighborhood.aws website.
