Getting Started with Claude 3 and the Claude 3 API
Learn about the Claude 3 models, detailed performance benchmarks, and how to access them. Additionally, discover the new Claude 3 Python API for generating text, accessing vision capabilities, and streaming.
13. März 2024
The AI war is still going strong, with Google's Gemini and Gemma making waves recently, but now Anthropic’s Claude 3 has emerged as a powerful contender, outperforming GPT-4 and Gemini Ultra on all benchmarks.
In this tutorial, we will explore Claude 3 models, performance benchmarks, and how to access them. We will also compare Claude 3 with its predecessor, Claude 2.1, and ChatGPT. Finally, we will learn about Claude 3's Python API for generating text, accessing vision capabilities, streaming responses, and using it asynchronously.
What is Claude 3?
Anthropic has recently introduced a new family of AI models called Claude 3. These models set industry benchmarks in various cognitive tasks. The Claude 3 models include three state-of-the-art models: Haiku, Sonnet, and Opus. These models can power real-time customer chats, auto-completions, and data extraction tasks.
Currently, Opus and Sonnet are available for claude.ai and the Claude API, while the smaller model Haiku will be released soon. The Claude 3 models are better at following complex, multi-step instructions, adhering to brand voice and response guidelines, and generating structured output in formats like JSON.
Compared to previous Claude models, these new models show improved contextual understanding, resulting in fewer unnecessary refusals.
They offer a 200K context window but can process inputs exceeding 1 million tokens. Specifically, Claude 3 Opus achieved near-perfect recall, surpassing 99% accuracy.
To ensure the trustworthiness of the models, Anthropic has dedicated teams to track and mitigate a broad spectrum of risks.

API and SDK
The third way to access the Claude 3 models is through API. Antropic offers client Software Development Kits (SDKs) for Python and Typescript. You can also access the model through the REST API by using the curl command in the terminal.
curl https://api.anthropic.com/v1/messages \
--header "x-api-key: $ANTHROPIC_API_KEY" \
--header "anthropic-version: 2023-06-01" \
--header "content-type: application/json" \
--data \
'{
"model": "claude-3-opus-20240229",
"max_tokens": 1024,
"messages": [
{"role": "user", "content": "How many moons does Jupiter have?"}
]
}'A Dive into Benchmarks
The Claude 3 models have been benchmarked against the top-performing large Language models (LLMs) and have shown significant improvements in various tests.
Claude 3 Opus, in particular, has outperformed GPT-4 and Gemini Ultra on some of the most common evaluation benchmarks, including MMLU, GPQA, and GSM8K. It exhibits near-human levels of comprehension and fluency on complex tasks, making it the first step towards achieving general intelligence.

Claude 3 models have gotten better at analysis and forecasting, code generation, and generating responses in non-English languages, as seen from the Benchmark data below:
Claude 3 model's visual capabilities have significantly improved, enabling it to comprehend complex photos, diagrams, and charts. This advancement benefits businesses with knowledge bases in various formats, such as PDFs, flowcharts, and presentation slides.
The Claude 3 models have also significantly improved in reducing unnecessary refusals and accuracy compared to previous generations of models.
Finally, we can see that the Claude 3 models exhibit a two-fold improvement in accuracy on open-ended questions compared to Claude 2.1. Additionally, the new models show reduced levels of incorrect answers.
Claude 3 Opus vs Claude 2.1
In this section, we will compare the responses of Claude 3 Opus and Claude 2.1 on three common tasks to understand their respective performances.
Q&A
Prompt: I speak without a mouth and hear without ears. I have no body, but I come alive with wind. What am I?
Claude 2.1 refused to answer the question, citing a lack of content. However, the user was asking a riddle, and Claude Opus provided the correct response.
Generating Code
Prompt: Create a FastAPI web application for a simple Scikit-learn classification model.
Claude 2.1 code appeared to have worked initially, but it raised an error after entering the sample values. Upon investigation, we discovered that the code is not optimized and the inference function has some mistakes.
On the other hand, when we compared it with the Claude 3 Opus, we found that the code ran smoothly and provided accurate predictions, as shown below.
Complex Problem
Prompt: How does a neural network with one layer and one input and output compare to a logistic regression?
Both models provided similar answers, but Claude 3 Opus' response was more detailed and easily readable.
Claude 3 Opus vs ChatGPT 4
Let us compare Claude 3 Opus and ChatGPT 4 on similar tasks as above to showcase how Claude 3 has a small edge over the GPT-4 model.
Q&A
Prompt: How many moons does Jupiter have?
Both statements are incorrect. As of February 5th, 2024, Jupiter has 95 moons. This prompt is useful in understanding the cutoff period for datasets. It appears that Claude 3 Opus was trained on an older dataset from 2021, while ChatGPT was last updated in April 2023.
Generating Code
Prompt: Creating a Gradio web application for a simple Scikit-learn classification model.
Claude 3 model generated code ran smoothly, but the code generated by GPT-4 failed to run due to multiple errors and hallucinations.
Complex Problem
Prompt: There are four people in an elevator and four floors in a building. What’s the probability that each person gets off on a different floor?
Both models came up with the correct answer to the famous probability question. One provided the mathematical work, and the other generated and ran Python code to display the same answer. In this case, both win.
Claude 3 Python SDK
In this part, we will learn about Claude 3 Python SDK and how we can use it to generate customized responses.
Getting Started
1. Install the anthropic Python package using PIP.
pip install anthropic2. Before we install the Python Package, we need to go to https://console.anthropic.com/dashboard and get the API key.
3. Set the ANTHROPIC_API_KEY environment variable and provide the value with the API key. Setting up and accessing the environment variable is quite easy in DataLab, DataCamp's AI-enabled data notebook.
4. Create the client object using the API key. We will use this client for text generation, access vision capability, and streaming.
import os
import anthropic
client = anthropic.Anthropic(
api_key=os.environ["ANTHROPIC_API_KEY"],
)Claude 2 Completions API
It's important to note that the newer Claude 3 model does not use the Completion API. If you attempt to use this API for the Claude 3 models, it will result in an error, and you will be advised to use the Messages API instead.
from IPython.display import Markdown, display
from anthropic import HUMAN_PROMPT, AI_PROMPT
completion = client.completions.create(
model="claude-2.1",
max_tokens_to_sample=300,
prompt=f"{HUMAN_PROMPT} What is Matthew effect? {AI_PROMPT}",
)
Markdown(completion.completion)

Claude 3 Messages API
To clarify, we will be testing the Anthropic Messages API for the Claude 3 Opus model. This API is similar to the Completion API, but it requires a messages argument to be provided as a list of dictionaries that contain the role and content.
Prompt = "Write the Go code for the simple data analysis."
message = client.messages.create(
model="claude-3-opus-20240229",
max_tokens=1024,
messages=[
{"role": "user", "content": Prompt}
]
)
Markdown(message.content[0].text)Using IPython Markdown will display the response in Markdown format. Meaning it will show bullet points, code blocks, headings, and links in a clean way.
The code works perfectly, and the explanation is clear enough for anyone to understand what is going on.
Adding System Prompt
We can customize the response by providing the system prompt. We have asked it to convert all the responses into Swedish.
Prompt = "Write a report on climate change."
message = client.messages.create(
model="claude-3-opus-20240229",
max_tokens=1024,
system="Respond only in Svenska.",
messages=[
{"role": "user", "content": Prompt}
]
)
Markdown(message.content[0].text)It has perfectly generated a report on climate change in Svenska.
Claude 3 Vision Block
The Messages API includes vision capabilities. In this section, we will use two photos from Pexels.com to generate a response.
- Image 1: Photo by Debayan Chakraborty: https://www.pexels.com/photo/indian-blue-jay-20433278/
- Image 2: Photo by Rachel Xiao: https://www.pexels.com/photo/brown-pendant-lamp-hanging-on-tree-near-river-772429/
We will load the images using the httpx package and convert it into base64 encoding.
import base64
import httpx
media_type = "image/jpeg"
url_1 = "https://images.pexels.com/photos/20433278/pexels-photo-20433278/free-photo-of-indian-blue-jay.jpeg?auto=compress&cs=tinysrgb&w=1260&h=750&dpr=2"
image_encode_1 = base64.b64encode(httpx.get(url_1).content).decode("utf-8")
url_2 = "https://images.pexels.com/photos/772429/pexels-photo-772429.jpeg?auto=compress&cs=tinysrgb&w=1260&h=750&dpr=2"
image_encode_2 = base64.b64encode(httpx.get(url_2).content).decode("utf-8")Vision with a Single Image
To inquire about the images, we need to provide Claude 3 API with image data, encoding type, and media type. Both the image and prompt are part of the content dictionary for the message argument.
message = client.messages.create(
model="claude-3-opus-20240229",
max_tokens=1024,
messages=[
{
"role": "user",
"content": [
{
"type": "image",
"source": {
"type": "base64",
"media_type": media_type,
"data": image_encode_1,
},
},
{
"type": "text",
"text": "Describe the image."
}
],
}
],
)
Markdown(message.content[0].text)
Vision with Multiple Images
Adding multiple images can be complex, but if you follow the code pattern in the code example, you will understand how it works.
We simply need to create text that points out Image 1 and Image 2, and then ask questions about these two images.
message = client.messages.create(
model="claude-3-opus-20240229",
max_tokens=1024,
messages=[
{
"role": "user",
"content": [
{
"type": "text",
"text": "Image 1:"
},
{
"type": "image",
"source": {
"type": "base64",
"media_type": media_type,
"data": image_encode_1,
},
},
{
"type": "text",
"text": "Image 2:"
},
{
"type": "image",
"source": {
"type": "base64",
"media_type": media_type,
"data": image_encode_2,
},
},
{
"type": "text",
"text": "What do these images have in common?"
}
],
}
],
)
Markdown(message.content[0].text)Perfect. Both images feature birds.
Claude 3 Streaming API
Streaming refers to the process of generating text outputs in a continuous fashion, rather than waiting for the entire sequence to be generated before returning any output. With this technique, the output is generated token by token, which helps to minimize the perceived latency.
Instead of create, we will use the stream function to generate the streaming response.
To display the results, we will use with syntax and for loop to print the token as soon as they are available.
Prompt = "Write a Python code for typical data engineering workflow."
completion = client.messages.stream(
max_tokens=1024,
messages=[
{
"role": "user",
"content": Prompt,
}
],
model="claude-3-opus-20240229",
)
with completion as stream:
for text in stream.text_stream:
print(text, end="", flush=True)
Claude 3 Async API
Synchronous APIs execute requests sequentially and block them until a response is received before initiating the next call. On the other hand, asynchronous APIs allow multiple concurrent requests without blocking, making them more efficient and scalable.
We will initialize the async client using the AsyncAnthropic. Then, we will create the main function using the async keyword and run the function using the asyncio.run function.
Note: If you are using async in the Jupyter Notebook, try using await main(), instead of asyncio.run(main()).
import asyncio
from anthropic import AsyncAnthropic
async_client = AsyncAnthropic(
api_key=os.environ["ANTHROPIC_API_KEY"],
)
Prompt = "Could you explain what MLOps is and suggest some of the best tools to use for it?"
async def main() -> None:
message = await async_client.messages.create(
max_tokens=1024,
messages=[
{
"role": "user",
"content": Prompt,
}
],
model="claude-3-opus-20240229",
)
display(Markdown(message.content[0].text))
asyncio.run(main())
Combining Streaming with Async API
We can easily combine streaming with async methods by using the stream function of the async client. This way, we will be able to receive multiple requests and stream the responses, making the AI application scalable and robust.
async def main() -> None:
completion = async_client.messages.stream(
max_tokens=1024,
messages=[
{
"role": "user",
"content": Prompt,
}
],
model="claude-3-opus-20240229",
)
async with completion as stream:
async for text in stream.text_stream:
print(text, end="", flush=True)
asyncio.run(main())
