AWS Bedrock

Configure AWS Bedrock as an LLM provider in Mem0 with IAM authentication and Claude model support.

Setup

• Before using the AWS Bedrock LLM, make sure you have the appropriate model access from Bedrock Console.
• Model availability is per-region. anthropic.claude-sonnet-4-20250514-v1:0 supports on-demand inference in us-east-1 and ap-southeast-4; from any other region, use the cross-region inference profile ID us.anthropic.claude-sonnet-4-20250514-v1:0 instead.
• Install the AWS SDK for your language: pip install boto3 (Python) or npm install @aws-sdk/client-bedrock-runtime (TypeScript).
• Both SDKs fall back to the standard AWS credential chain (environment variables, ~/.aws/credentials, or an attached IAM role), so exporting AWS_REGION, AWS_ACCESS_KEY_ID, and AWS_SECRET_ACCESS_KEY is the quickest way to get started. In TypeScript you can also pass credentials inline with awsRegion, awsAccessKeyId, awsSecretAccessKey, and awsSessionToken, as shown below.

Usage

Python

import os
from mem0 import Memory

os.environ['AWS_REGION'] = 'us-east-1'
os.environ["AWS_ACCESS_KEY_ID"] = "xx"
os.environ["AWS_SECRET_ACCESS_KEY"] = "xx"

config = {
    "llm": {
        "provider": "aws_bedrock",
        "config": {
            "model": "anthropic.claude-sonnet-4-20250514-v1:0",
            "temperature": 0.2,
            "max_tokens": 2000,
        }
    }
}

m = Memory.from_config(config)
messages = [
    {"role": "user", "content": "I'm planning to watch a movie tonight. Any recommendations?"},
    {"role": "assistant", "content": "How about thriller movies? They can be quite engaging."},
    {"role": "user", "content": "I’m not a big fan of thriller movies but I love sci-fi movies."},
    {"role": "assistant", "content": "Got it! I'll avoid thriller recommendations and suggest sci-fi movies in the future."}
]
m.add(messages, user_id="alice", metadata={"category": "movies"})

import { Memory } from 'mem0ai/oss';

const config = {
  llm: {
    provider: 'aws_bedrock',
    config: {
      model: 'anthropic.claude-sonnet-4-20250514-v1:0',
      temperature: 0.2,
      maxTokens: 2000,
      // Optional. Omit these to use the default AWS credential chain.
      awsRegion: process.env.AWS_REGION,
      awsAccessKeyId: process.env.AWS_ACCESS_KEY_ID,
      awsSecretAccessKey: process.env.AWS_SECRET_ACCESS_KEY,
    },
  },
};

const memory = new Memory(config);
const messages = [
    {"role": "user", "content": "I'm planning to watch a movie tonight. Any recommendations?"},
    {"role": "assistant", "content": "How about thriller movies? They can be quite engaging."},
    {"role": "user", "content": "I’m not a big fan of thriller movies but I love sci-fi movies."},
    {"role": "assistant", "content": "Got it! I'll avoid thriller recommendations and suggest sci-fi movies in the future."}
];
await memory.add(messages, { userId: 'alice', metadata: { category: 'movies' } });

@aws-sdk/client-bedrock-runtime is an optional peer dependency of mem0ai, so npm will not install it for you. The TypeScript provider loads it lazily and throws a clear error on the first request if the package is missing.

The TypeScript provider calls the Bedrock Converse API, a single uniform interface across the current Bedrock model families. Streaming and InvokeModel-only models are not supported yet.
