Anthropic’s Claude 3.5 Sonnet model now available in Amazon Bedrock: Even more intelligence than Claude 3 Opus at one-fifth the cost

It’s been just 3 months since Anthropic launched Claude 3, a family of state-of-the-art artificial intelligence (AI) models that allows you to choose the right combination of intelligence, speed, and cost that suits your needs.

Today, Anthropic introduced Claude 3.5 Sonnet, its first release in the forthcoming Claude 3.5 model family. We are happy to announce that Claude 3.5 Sonnet is now available in Amazon Bedrock.

Claude 3.5 Sonnet raises the industry bar for intelligence, outperforming other generative AI models on a wide range of evaluations, including Anthropic’s previously most intelligent model, Claude 3 Opus. Claude 3.5 Sonnet is available with the speed and cost of the original Claude 3 Sonnet model. In fact, you can now get intelligence and speed better than Claude 3 Opus at one-fifth of the price because Claude 3.5 Sonnet is 80 percent cheaper than Opus.

The frontier intelligence displayed by Claude 3.5 Sonnet combined with cost-effective pricing, makes the model ideal for complex tasks such as context-sensitive customer support, orchestrating multi-step workflows, and streamlining code translations.

Claude 3.5 Sonnet sets new industry benchmarks for undergraduate-level expert knowledge (MMLU), graduate-level expert reasoning (GPQA), code (HumanEval), and more. As you can see in the following table, according to Anthropic, Claude 3.5 Sonnet outperforms OpenAI’s GPT-4o and Google’s Gemini 1.5 Pro in nearly every benchmark.

Claude 3.5 Sonnet is also Anthropic’s strongest vision model yet, performing an average of 10 percent better than Claude 3 Opus across the majority of vision benchmarks. According to Anthropic, Claude 3.5 Sonnet also outperforms other generative AI models in nearly every category.

Using Anthropic’s Claude 3.5 Sonnet in the Amazon Bedrock console
Because this is a new model, I go to the Amazon Bedrock console and choose Model access from the navigation pane to enable access to Claude 3.5 Sonnet.

Now that I have access to the model, I’d like to use it to extract information from the following image from the Our World in Data website:

I choose Chat in the Playgrounds section of the navigation pane and select Anthropic and Claude 3.5 Sonnet as the model. I then choose the Image upload button to upload the previous image, type the following prompt, and choose Run:

Which countries consume more than 1000 TWh from hydropower? Think step by step and look at all regions. Output in JSON.

Here’s the result and an animated image recapping what I did.

To determine which countries consume more than 1,000 TWh from hydropower in 2022, I need to carefully examine the map and color-coding. The scale at the bottom shows that dark blue represents consumption between 1,000 TWh and 2,000 TWh.

Let's look at each region systematically:

1. North America: Canada is dark blue, indicating it consumes between 1,000-2,000 TWh from hydropower.
2. South America: Brazil is dark blue, also consuming between 1,000-2,000 TWh.
3. Europe: No country is dark blue; all are light green or have no data.
4. Africa: No data available for any country.
5. Asia: China is dark blue, indicating consumption between 1,000-2,000 TWh.
6. Oceania: No country is dark blue; Australia is light green.

In summary, there are three countries that consume more than 1,000 TWh from hydropower in 2022:
1. Canada (North America)
2. Brazil (South America)
3. China (Asia)

Here's the response in JSON format:

```json
{
  "countries_consuming_over_1000TWh_hydropower": [
    {
      "name": "Canada",
      "region": "North America",
      "consumption_range": "1,000-2,000 TWh"
    },
    {
      "name": "Brazil",
      "region": "South America",
      "consumption_range": "1,000-2,000 TWh"
    },
    {
      "name": "China",
      "region": "Asia",
      "consumption_range": "1,000-2,000 TWh"
    }
  ]
}
```

These three countries stand out as the highest consumers of hydropower energy, each using between 1,000 and 2,000 terawatt-hours in 2022.

The model’s ability to reliably extract information from unstructured data, like images, opens up a world of new possibilities.

I choose the three small dots in the corner of the playground window and then View API request to see code examples using the model in the AWS Command Line Interface (AWS CLI) and AWS SDKs. Let’s have a better look at the code syntax.

Using Claude 3.5 Sonnet with AWS SDKs
You can use Claude 3.5 Sonnet with any AWS SDK using the new Amazon Bedrock Converse API or Anthropic Claude Messages API.

To update code already using a Claude 3 model, I just need to replace the model ID with:

anthropic.claude-3-5-sonnet-20240620-v1:0

Here’s a sample implementation with the AWS SDK for Python (Boto3) using the same image as before to show how to use images and text with the Converse API.

import boto3
from botocore.exceptions import ClientError

MODEL_ID = "anthropic.claude-3-5-sonnet-20240620-v1:0"

IMAGE_NAME = "primary-energy-hydro.png"

bedrock_runtime = boto3.client("bedrock-runtime", region_name="us-east-1")

with open(IMAGE_NAME, "rb") as f:
    image = f.read()

user_message = "Which countries consume more than 1000 TWh from hydropower? Think step by step and look at all regions. Output in JSON."

messages = [
    {
        "role": "user",
        "content": [
            {"image": {"format": "png", "source": {"bytes": image}}},
            {"text": user_message},
        ],
    }
]

response = bedrock_runtime.converse(
    modelId=MODEL_ID,
    messages=messages,
)
response_text = response["output"]["message"]["content"][0]["text"]
print(response_text)

When I run it, I get a similar output as in the console:

Let's approach this step-by-step:

1. First, I'll examine the color scale at the bottom of the map. The darkest blue color represents consumption of 2,000 TWh or more.

2. Now, I'll scan the map region by region:

   North America: Canada is dark blue, indicating over 1,000 TWh.
   South America: Brazil is also dark blue, over 1,000 TWh.
   Europe: No country appears to be dark blue.
   Africa: No country appears to be dark blue.
   Asia: China stands out as dark blue, indicating over 1,000 TWh.
   Oceania: No country appears to be dark blue.

3. To be thorough, I'll double-check for any medium blue countries that might be close to or over 1,000 TWh, but I don't see any that appear to reach that threshold.

4. Based on this analysis, there are three countries that clearly consume more than 1,000 TWh from hydropower.

Now, I'll format the answer in JSON:

```json
{
  "countries_consuming_over_1000TWh_hydropower": [
    "Canada",
    "Brazil",
    "China"
  ]
}
```

This JSON output lists the three countries that visually appear to consume more than 1,000 TWh of primary energy from hydropower according to the 2022 data presented in the map.

Because I didn’t specify a JSON syntax, the two answers use a different format. In your applications, you can describe in the prompt the JSON properties you want or provide a sample to get a standard format in output.

For more examples, see the code samples in the Amazon Bedrock User Guide. For a more advanced use case, here’s a fully functional tool use demo illustrating how to connect a generative AI model with a custom tool or API.

Using Claude 3.5 Sonnet with the AWS CLI
There are times when nothing beats the speed of the command line. This is how you can use the AWS CLI with the new model:

aws bedrock-runtime converse \
    --model-id anthropic.claude-3-5-sonnet-20240620-v1:0 \
    --messages '{"role": "user", "content": [{"text": "Alice has N brothers and she also has M sisters. How many sisters does Alice’s brother have?"}]}' \
    --region us-east-1
    --query output.message.content

In the output, I use the query option to only get the content of the output message:

[
    {
        "text": "Let's approach this step-by-step:\n\n1. First, we need to understand the relationships:\n   - Alice has N brothers\n   - Alice has M sisters\n\n2. Now, let's consider Alice's brother:\n   - He is one of Alice's N brothers\n   - He has the same parents as Alice\n\n3. This means that Alice's brother has:\n   - The same sisters as Alice\n   - One sister more than Alice (because Alice herself is his sister)\n\n4. Therefore, the number of sisters Alice's brother has is:\n   M + 1\n\n   Where M is the number of sisters Alice has.\n\nSo, the answer is: Alice's brother has M + 1 sisters."
    }
]

I copy the text into a small Python program to see it printed on multiple lines:

print("Let's approach this step-by-step:\n\n1. First, we need to understand the relationships:\n   - Alice has N brothers\n   - Alice has M sisters\n\n2. Now, let's consider Alice's brother:\n   - He is one of Alice's N brothers\n   - He has the same parents as Alice\n\n3. This means that Alice's brother has:\n   - The same sisters as Alice\n   - One sister more than Alice (because Alice herself is his sister)\n\n4. Therefore, the number of sisters Alice's brother has is:\n   M + 1\n\n   Where M is the number of sisters Alice has.\n\nSo, the answer is: Alice's brother has M + 1 sisters.")

Let's approach this step-by-step:

1. First, we need to understand the relationships:
   - Alice has N brothers
   - Alice has M sisters

2. Now, let's consider Alice's brother:
   - He is one of Alice's N brothers
   - He has the same parents as Alice

3. This means that Alice's brother has:
   - The same sisters as Alice
   - One sister more than Alice (because Alice herself is his sister)

4. Therefore, the number of sisters Alice's brother has is:
   M + 1

   Where M is the number of sisters Alice has.

So, the answer is: Alice's brother has M + 1 sisters.

Even if this was a quite nuanced question, Claude 3.5 Sonnet got it right and described its reasoning step by step.
