Amazon Bedrock

Run foundation models on AWS with BedrockModel — Claude, Nova, Llama, Mistral, and more. Best when you need AWS-native deployment, IAM-based auth, and enterprise compliance.

For standalone invoke / stream usage, see LLM Models — Amazon Bedrock.

Install

pip install --extra-index-url https://elsai-agents.elsai.ai/root/ elsai-agents==0.3.1
pip install --extra-index-url https://core-packages.elsai.ai/root/ "elsai-model[bedrock]==2.1.0"

Setup

1. Enable model access in the Amazon Bedrock console.
2. Configure AWS credentials (environment variables, aws configure, or an IAM role).
3. Export your chosen model ID:

export AWS_ACCESS_KEY_ID=...
export AWS_SECRET_ACCESS_KEY=...
export AWS_DEFAULT_REGION=us-west-2
export BEDROCK_MODEL_ID=global.anthropic.claude-sonnet-4-6

Bare Agent() (no model=) uses the same defaults: Claude Sonnet 4.6 in us-west-2.

Agent — basic

import os
from elsai import Agent
from elsai_model import LLM, Provider

model = LLM(
    provider=Provider.BEDROCK,
    model=os.getenv("BEDROCK_MODEL_ID", "global.anthropic.claude-sonnet-4-6"),
    region_name=os.getenv("AWS_DEFAULT_REGION", os.getenv("AWS_REGION", "us-west-2")),
    max_tokens=256,
    temperature=0.2,
)
agent = Agent(
    model=model,
    system_prompt="You are a concise assistant.",
)
result = agent("Summarize what an AI agent is in two sentences.")
print(result)
