Picture by Writer
On this tutorial, we’ll discover ways to arrange and use the OpenAI API for varied use instances. The tutorial is designed to be straightforward to comply with, even for these with restricted information of Python programming. We’ll discover how anybody can generate responses and entry high-quality massive language fashions.
The OpenAI API permits builders to simply entry a variety of AI fashions developed by OpenAI. It offers a user-friendly interface that allows builders to include clever options powered by state-of-the-art OpenAI fashions into their functions. The API can be utilized for varied functions, together with textual content era, multi-turn chat, embeddings, transcription, translation, text-to-speech, picture understanding, and picture era. Moreover, the API is appropriate with curl, Python, and Node.js.
To get began with OpenAI API, you first have to create an account on openai.com. Beforehand, each person was given free credit score, however now new customers are required to buy credit score.
To buy credit score, go to “Settings,” then “Billing,” and at last, “Add Fee Particulars.” Enter your debit or bank card data, and ensure to disable auto-recharge. After getting loaded 10 USD, you should utilize it for a yr.
Let’s create the API key by navigating to “API keys” and deciding on “Create new secret key”. Give it a reputation and click on on “Create secret key”.
Copy the API and create an Setting variable on the native machine.
I take advantage of Deepnote as my IDE. It is easy to create surroundings variables. Merely go to “Integration”, choose “create surroundings variable”, present a reputation and worth for the important thing, and create the combination.
Subsequent, we’ll Set up the OpenAI Python bundle utilizing pip.
%pip set up --upgrade openai
We’ll now create a shopper that may entry varied sorts of fashions globally.
In case you have set your surroundings variable with the title “OPENAI_API_KEY”, you need not present the OpenAI shopper with an API key.
from openai import OpenAI
shopper = OpenAI()
Please notice that it’s best to solely present an API key if the title of your surroundings variable is completely different from the default one.
import os
from openai import OpenAI
shopper = OpenAI(
api_key=os.environ.get("SECRET_KEY"),
)
We’ll use a legacy perform to generate the response. The completion perform requires the mannequin title, immediate, and different arguments to generate the reply.
completion = shopper.completions.create(
mannequin="gpt-3.5-turbo-instruct",
immediate="Write a brief story about Elon Musk being the largest troll.",
max_tokens=300,
temperature=0.7,
)
print(completion.decisions[0].textual content)
The GPT3.5 mannequin have generate wonderful story about Elon Musk.
We are able to additionally stream our response by offering an additional argument `stream`.
As a substitute of ready for the whole response, the stream characteristic permits processing of output as quickly because it’s generated. This method helps to cut back perceived latency by returning the output of the language mannequin token by token slightly than abruptly.
stream = shopper.completions.create(
mannequin="gpt-3.5-turbo-instruct",
immediate="Write a Python code for accessing the REST API securely.",
max_tokens=300,
temperature=0.7,
stream = True
)
for chunk in stream:
print(chunk.decisions[0].textual content, finish="")
The mannequin used API chat completion. Earlier than producing the response, let’s discover the accessible fashions.
You may view the record of all fashions accessible or learn the Models web page on the official documentation.
print(shopper.fashions.record())
We’ll use the newest model of GPT-3.5 and supply it with an inventory of a dictionary for system prompts and person messages. Make sure that to comply with the identical message sample.
completion = shopper.chat.completions.create(
mannequin="gpt-3.5-turbo-1106",
messages=[
{
"role": "system",
"content": "You are an experienced data scientist, adept at presenting complex data concepts with creativity.",
},
{
"role": "user",
"content": "What is Feature Engineering, and what are some common methods?",
},
],
)
print(completion.decisions[0].message.content material)
As we are able to see, we have now generated an identical end result because the legacy API. So, why use this API? Subsequent, we’ll study why the chat completion API is extra versatile and simpler to make use of.
Function engineering is the method of choosing, creating, or reworking options (variables) in a dataset to enhance the efficiency of machine studying fashions. It entails figuring out probably the most related and informative options and getting ready them for mannequin coaching. Efficient characteristic engineering can considerably improve the predictive energy of a mannequin and its capability to generalize to new knowledge.
Some widespread strategies of characteristic engineering embrace:
1. Imputation: Dealing with lacking values in options by filling them in with significant values such because the imply, median, or mode of the characteristic.
2. One-Sizzling Encoding: Changing categorical variables into binary vectors to characterize completely different classes as particular person options.
3. Normalization/Standardization: Scaling numerical options to carry t.........
We’ll now discover ways to have a multi-turn dialog with our AI mannequin. To do that, we’ll add the assistant’s response to the earlier dialog and likewise embrace the brand new immediate in the identical message format. After that, we’ll present an inventory of dictionaries to the chat completion perform.
chat=[
{"role": "system", "content": "You are an experienced data scientist, adept at presenting complex data concepts with creativity."},
{"role": "user", "content": "What is Feature Engineering, and what are some common methods?"}
]
chat.append({"position": "assistant", "content material": str(completion.decisions[0].message.content material)})
chat.append({"position": "person", "content material": "Are you able to summarize it, please?"})
completion = shopper.chat.completions.create(
mannequin="gpt-3.5-turbo-1106",
messages=chat
)
print(completion.decisions[0].message.content material)
The mannequin has understood the context and summarized the characteristic engineering for us.
Function engineering entails deciding on, creating, or reworking options in a dataset to boost the efficiency of machine studying fashions. Widespread strategies embrace dealing with lacking values, changing categorical variables, scaling numerical options, creating new options utilizing interactions and polynomials, deciding on essential options, extracting time-series and textual options, aggregating data, and lowering characteristic dimensionality. These methods intention to enhance the mannequin's predictive energy by refining and enriching the enter options.
To develop superior functions, we have to convert textual content into embeddings. These embeddings are used for similarity search, semantic search, and advice engines. We are able to generate embeddings by offering the API textual content and mannequin title. It’s that easy.
textual content = "Knowledge Engineering is a quickly rising area that focuses on the gathering, storage, processing, and evaluation of huge volumes of structured and unstructured knowledge. It entails varied duties comparable to knowledge extraction, transformation, loading (ETL), knowledge modeling, database design, and optimization to make sure that knowledge is accessible, correct, and related for decision-making functions."
DE_embeddings = shopper.embeddings.create(enter=textual content, mannequin="text-embedding-3-small")
print(chat_embeddings.knowledge[0].embedding)
