In today’s highly competitive e-commerce landscape, personalized product recommendations are crucial for businesses to attract and retain customers. Machine learning algorithms can help achieve this goal by analyzing customer data and providing recommendations based on their preferences and behavior. In this article, I will explore how to code a product recommendation system using Python and the ChatGPT language model. We will leverage its capabilities to create a recommendation system that can suggest products to customers based on their previous purchases and browsing history.
Video explanation what we are going to code
Although the video demonstrates the execution of ChatGPT within the Tracardi platform, we will not be reproducing this process. Instead, we will examine the coding of the plugin to learn the methodology employed, which we can apply to our own projects.
If you’re interested in using Tracardi for your projects or contributing to its development, you can access its repository on GitHub. Tracardi is an open-source project that allows developers to create highly customizable automation workflows and customer journey maps.
I encourage you to give them at least a github star for sharing how to use ChatGPT in product recommendations.
Getting started
To start using ChatGPT API, you will need to create an account with OpenAI and obtain an API key. The API key will give you access to the GPT-4 language model, which you can then use to generate text in a variety of contexts.
There are multiple pricing models available, each with different capabilities and price points. The pricing is based on the number of tokens you use, with 1,000 tokens roughly equivalent to 750 words.
You don’t need to worry about the price of ChatGPT, as the pricing is quite reasonable for programmers and I have personally used it for a while without paying more than a dollar.
Library installation
The OpenAI API can be accessed through HTTP requests from any programming language using either the official Python bindings. To install the official Python bindings, use the command:
pip install openaipip install openaipip install openai

As I mentioned the API uses API keys for authentication, which can be obtained from the API Keys page. Remember to keep your API key secure and not expose it in any client-side code.
All API requests should include your API key in an Authorization HTTP header as follows:
Authorization: Bearer OPENAI_API_KEYAuthorization: Bearer OPENAI_API_KEYAuthorization: Bearer OPENAI_API_KEY

Requesting organization
For users who belong to multiple organizations, you can pass a header to specify which organization is used for an API request. Usage from these API requests will count against the specified organization’s subscription quota.
Example curl command:
curl https://api.openai.com/v1/models \-H "Authorization: Bearer $OPENAI_API_KEY" \-H "OpenAI-Organization: YOUR_ORG_ID"curl https://api.openai.com/v1/models \ -H "Authorization: Bearer $OPENAI_API_KEY" \ -H "OpenAI-Organization: YOUR_ORG_ID"curl https://api.openai.com/v1/models \ -H "Authorization: Bearer $OPENAI_API_KEY" \ -H "OpenAI-Organization: YOUR_ORG_ID"

Making requests
To make your first API request, simply copy and paste the command below into your terminal. Just be sure to replace “$OPENAI_API_KEY” with your own secret API key.
Tracardi utilizes asynchronous API calls using asyncio, so it doesn’t use the openai library. Therefore, I will adopt the same method and use raw REST API calls instead of the library. This approach will make the code more efficient and flexible.
To make an API call, you can use any existing library that you are familiar with. For simplicity, I will use the requests library.
We will be using the “https://api.openai.com/v1/completions” POST endpoint.
The plugin sends the following payload to that API, where prompt is the actual prompt:
<span>prompt_length</span> <span>=</span> <span>len</span><span>(</span><span>prompt</span><span>.</span><span>split</span><span>())</span><span>max_tokens</span> <span>=</span> <span>1024</span> <span>-</span> <span>prompt_length</span><span>payload</span> <span>=</span> <span>{</span><span>"model"</span><span>:</span> <span>"text-davinci-003"</span><span>,</span><span>"prompt"</span><span>:</span> <span>prompt</span><span>,</span><span>"max_tokens"</span><span>:</span> <span>max_tokens</span><span>,</span><span>"temperature"</span><span>:</span> <span>0.5</span><span>,</span><span>"top_p"</span><span>:</span> <span>1</span><span>,</span><span>"n"</span><span>:</span> <span>1</span><span>}</span><span>prompt_length</span> <span>=</span> <span>len</span><span>(</span><span>prompt</span><span>.</span><span>split</span><span>())</span> <span>max_tokens</span> <span>=</span> <span>1024</span> <span>-</span> <span>prompt_length</span> <span>payload</span> <span>=</span> <span>{</span> <span>"model"</span><span>:</span> <span>"text-davinci-003"</span><span>,</span> <span>"prompt"</span><span>:</span> <span>prompt</span><span>,</span> <span>"max_tokens"</span><span>:</span> <span>max_tokens</span><span>,</span> <span>"temperature"</span><span>:</span> <span>0.5</span><span>,</span> <span>"top_p"</span><span>:</span> <span>1</span><span>,</span> <span>"n"</span><span>:</span> <span>1</span> <span>}</span>prompt_length = len(prompt.split()) max_tokens = 1024 - prompt_length payload = { "model": "text-davinci-003", "prompt": prompt, "max_tokens": max_tokens, "temperature": 0.5, "top_p": 1, "n": 1 }

Integrating ChatGPT response with your code
Tracardi has implemented a clever trick to integrate ChatGPT response with their code. They ask the chat to respond in JSON format, which is then parsed into a dictionary that can be used in the code.
To generate the desired response from ChatGPT, you need to provide the right prompt. Tracardi uses the following prompt for their use case:
Customer bought HERE_LIST_OF_PRODUCTS. What other products would you suggest to this customer? Please provide at least 3 suggestions as a pair of product name and category. Respond with a JSON list of objects.Customer bought HERE_LIST_OF_PRODUCTS. What other products would you suggest to this customer? Please provide at least 3 suggestions as a pair of product name and category. Respond with a JSON list of objects.Customer bought HERE_LIST_OF_PRODUCTS. What other products would you suggest to this customer? Please provide at least 3 suggestions as a pair of product name and category. Respond with a JSON list of objects.

Make sure to replace HERE_LIST_OF_PRODUCTS with the actual list of products that the customer bought.
So our code could look like this:

We need to parse “choices” into dict and we can use the response in python code.
Here is the code to do that:

We can certainly improve the accuracy of the prompt by including more specific information about our products. For example:
Customer bought {list_of_products}. What other products would you suggest to this customer, knowing that we sell {list_of_our_product_categories}. Please provide at least 3 suggestions as a pair of product name and category. Respond with a JSON list of objects in "choices" key.Customer bought {list_of_products}.
