Using Jurassic-2 Mid on AWS Bedrock

Implementation guide · Jurassic-2 · AI21 Labs

Serverless

Quick Start

  1. 1
    Create an account at AWS Bedrock and generate an API key.
  2. 2
    Use the AWS Bedrock SDK or REST API to call jurassic-2-mid — see the documentation for request format.
  3. 3
    You'll be billed $12.50/1M input, $12.50/1M output tokens. See full pricing.

Code Examples

Install
pip install boto3
API key
AWS_ACCESS_KEY_ID
Model ID
jurassic-2-mid

Use Amazon Bedrock model IDs, e.g. "anthropic.claude-3-opus-20240229-v1:0" for on-demand, or cross-region inference profile IDs like "us.anthropic.claude-opus-4-7-20251101-v1:0". These differ from the public model slug.

import boto3

# Reads AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_DEFAULT_REGION from env
client = boto3.client("bedrock-runtime", region_name="us-east-1")
response = client.converse(
    modelId="jurassic-2-mid",
    messages=[{
        "role": "user",
        "content": [{"text": "Hello"}]
    }]
)
print(response["output"]["message"]["content"][0]["text"])

About Jurassic-2 Mid

Jurassic-2 Mid, developed by AI21 Labs, is a large language model that balances quality, speed, and cost, making it well-suited for complex language tasks such as chatbots and conversational interfaces. It has a parameter size of 17 billion and supports multiple languages including Spanish, French, German, Portuguese, Italian, and Dutch. Optimized for generating precise text from instruction-only prompts, the model is capable of zero-shot text generation without requiring examples. Despite its powerful capabilities, it shares common limitations with other LLMs, such as potential inaccuracies, lack of coherence, and the presence of training data biases. It was trained on a vast corpus of roughly 1.2 trillion tokens from diverse sources like CommonCrawl, Wikipedia, and Stack Exchange. Jurassic-2 Mid has an end-of-life date set for November 14, 2024 12.
