Nova 2 Lite helps textual content, picture, video, doc as enter and provides a one million-token context window, enabling expanded reasoning and richer in-context studying. As well as, Nova 2 Lite might be custom-made in your particular enterprise wants. The mannequin additionally consists of entry to 2 built-in instruments: internet grounding and a code interpreter. Internet grounding retrieves publicly out there info with citations, whereas the code interpreter permits the mannequin to run and consider code inside the identical workflow.
Amazon Nova 2 Lite demonstrates robust efficiency throughout numerous analysis benchmarks. The mannequin excels in core intelligence throughout a number of domains together with instruction following, math, and video understanding with temporal reasoning. For agentic workflows, Nova 2 Lite exhibits dependable perform calling for activity automation and exact UI interplay capabilities. The mannequin additionally demonstrates robust code era and sensible software program engineering problem-solving skills.
Nova 2 Lite is constructed to fulfill your organization’s wants
Nova 2 Lite can be utilized for a broad vary of your on a regular basis AI duties. It provides the very best mixture of worth, efficiency, and velocity. Early clients are utilizing Nova 2 Lite for customer support chatbots, doc processing, and enterprise course of automation.
Nova 2 Lite may help help workloads throughout many alternative use instances:
- Enterprise purposes – Automate enterprise course of workflow, clever doc processing (IDP), buyer help, and internet search to enhance productiveness and outcomes
- Software program engineering – Generate code, debugging, refactoring, and migrating programs to speed up improvement and improve effectivity
- Enterprise intelligence and analysis – Use long-horizon reasoning and internet grounding to investigate inner and exterior sources to uncover insights, and make knowledgeable choices
For particular necessities, Nova 2 Lite can also be out there for personalization on each Amazon Bedrock and Amazon SageMaker AI.
Utilizing Amazon Nova 2 Lite
Within the Amazon Bedrock console, you should use the Chat/Textual content playground to shortly check the brand new mannequin together with your prompts. To combine the mannequin into your purposes, you should use any AWS SDKs with the Amazon Bedrock InvokeModel and Converse API. Right here’s a pattern invocation utilizing the AWS SDK for Python (Boto3).
import boto3
AWS_REGION="us-east-1"
MODEL_ID="international.amazon.nova-2-lite-v1:0"
MAX_REASONING_EFFORT="low" # low, medium, excessive
bedrock_runtime = boto3.consumer("bedrock-runtime", region_name=AWS_REGION)
# Allow prolonged considering for advanced problem-solving
response = bedrock_runtime.converse(
modelId=MODEL_ID,
messages=[{
"role": "user",
"content": [{"text": "I need to optimize a logistics network with 5 warehouses, 12 distribution centers, and 200 retail locations. The goal is to minimize total transportation costs while ensuring no location is more than 50 miles from a distribution center. What approach should I take?"}]
}],
additionalModelRequestFields={
"reasoningConfig": {
"kind": "enabled", # enabled, disabled (default)
"maxReasoningEffort": MAX_REASONING_EFFORT
}
}
)
# The response will include reasoning blocks adopted by the ultimate reply
for block in response["output"]["message"]["content"]:
if "reasoningContent" in block:
reasoning_text = block["reasoningContent"]["reasoningText"]["text"]
print(f"Nova's considering course of:n{reasoning_text}n")
elif "textual content" in block:
print(f"Last advice:n{block['text']}")You too can use the brand new mannequin with agentic frameworks that helps Amazon Bedrock and deploy the brokers utilizing Amazon Bedrock AgentCore. On this approach, you’ll be able to construct brokers for a broad vary of duties. Right here’s the pattern code for an interactive multi-agent system utilizing the Strands Brokers SDK. The brokers have entry to a number of instruments, together with learn and write file entry and the likelihood to run shell instructions.
from strands import Agent
from strands.fashions import BedrockModel
from strands_tools import calculator, editor, file_read, file_write, shell, http_request, graph, swarm, use_agent, assume
AWS_REGION="us-east-1"
MODEL_ID="international.amazon.nova-2-lite-v1:0"
MAX_REASONING_EFFORT="low" # low, medium, excessive
SYSTEM_PROMPT = (
"You're a useful assistant. "
"Observe the directions from the consumer. "
"That will help you together with your duties, you'll be able to dynamically create specialised brokers and orchestrate advanced workflows."
)
bedrock_model = BedrockModel(
region_name=AWS_REGION,
model_id=MODEL_ID,
additional_request_fields={
"reasoningConfig": {
"kind": "enabled", # enabled, disabled (default)
"maxReasoningEffort": MAX_REASONING_EFFORT
}
}
)
agent = Agent(
mannequin=bedrock_model,
system_prompt=SYSTEM_PROMPT,
instruments=[calculator, editor, file_read, file_write, shell, http_request, graph, swarm, use_agent, think]
)
whereas True:
attempt:
immediate = enter("nEnter your query (or 'give up' to exit): ").strip()
if immediate.decrease() in ['quit', 'exit', 'q']:
break
if len(immediate) > 0:
agent(immediate)
besides KeyboardInterrupt:
break
besides EOFError:
break
print("nGoodbye!")Issues to know
