1. Overview
Magento 2 ChatGPT extension enables you to integrate ChatGPT into your store to automatically generate high-quality & SEO-friendly content for all your pages.
2. How Does It Work?
Magento 2 ChatGPT module only helps integrate ChatGPT into Magento site. To use the ChatGPT service, you need an OpenAI account.
In your OpenAI account, on Billing overview, you will see what type of account (Free trial or Paid account), and Credit remaining.
To set up a paid account, click Add payment details and set the appropriate payment information.
2.1. Enable the extension
Please go to Stores ⇒ Configuration ⇒ BSS COMMERCE ⇒ ChatGPT ⇒ ChatGPT Configuration.
- Enable: Choose Yes to enable the module or No to disable it.
- API Key: Enter the API key provided by ChatGPT. To get the API key, please follow the ChatGPT API guide.
- Model Type: Choose the model type of the ChatGPT (ChatGPT-3.5 Turbo or ChatGPT-4). For more details, please follow the ChatGPT Model guide.
- Max Tokens (Store view): Enter the token limitation of the model. Only an integer greater than 0 is valid. For more details, please follow the ChatGPT Tokens guide.
*Note:
- You should enter an integer number greater than 1000 and less than the max tokens provided by ChatGPT.
- The value in this field will automatically change to the default value of the respective ChatGPT model.
- If the language you use is not English, you should input a lower number of Max Tokens because ChatGPT may not be able to tokenize your words in a standard way. You can test the token length of your prompt here.
- Learn more about how to set Max Tokens value for Languages Other Than English (LOTE) here. - Temperature: Enter a real number: 0 <= x <= 2. For more details, please follow the ChatGPT Temperature guide.
*Note:
Higher values like 0.8 will make the output more random, while lower values like 0.2 will make it more focused and deterministic. See: ChatGPT Temperature in FAQs. - Call ChatGPT: Click the button to check the configurations after editing them.
*Note: When you click the button, it will use the current configurations on the page to check. You don't need to save configs before calling it.
2.2. Default prompts
Default prompts appear when you use the Get Default Prompt config, which acts like the query to send to the ChatGPT system to command the AI to write content for you.
Go to Stores ⇒ Configuration ⇒ BSS COMMERCE ⇒ ChatGPT ⇒ Default Prompts.
Default Prompts are divided into smaller sections: Product Prompts, Category Prompts, CMS Prompts, and SEO Prompts.
- ChatGPT System role: Each of these prompts will include the ChatGPT System role section to define the role of ChatGPT when generating answers for the section below. Example: A professional eCommerce advertisement content writer who is proficient in SEO, A professional SEO expert in eCommerce, ….
- Product Prompts: The default prompt to write content for long and short product descriptions.

3. Set Max Tokens value for non-English language
Our module uses ChatGPT's fixed formula to calculate the max token for the answer (completion).
According to the ChatGPT's doc: A helpful rule of thumb is that one token corresponds generally to 4 characters of text for common English text. This translates to roughly ¾ of a word (so 100 tokens = 75 words).
For example: You're using Chinese (a non-English language).
Given that the max token input in ChatGPT configuration is 4097 tokens.
If your prompt has 260 characters, the module calculates that:
- The token number of the prompt is 260/4 = 65 tokens.
- The max tokens for the answer that the module request ChatGPT to generate is approximately 4097 - 65 = 4032 tokens.
However, because you're using Chinese, ChatGPT calculates the token number of the prompt as 434 tokens (test it here). The reason is that it takes a lot of tokens to tokenize figurative language (Chinese in this case) for ChatGPT to understand, increasing the prompt token significantly.
So after you use that prompt and call ChatGPT, ChatGPT will automatically generate an answer according to the max token value the module request sent (in this case, 3931 tokens), and then compare it with the model's max token.
An error occurred due to: 434 (prompt) + 3931 (completion) = 4365 tokens => Exceeded max token of the module => The module will report the error and did not print that completion in the Magento text field.
Thus, if the language is not English, you should input a lower number of Max Tokens.
