GPT-3 is a powerful language model that can generate natural language text for a variety of tasks, such as text completion, text summarization, text translation, and more. However, GPT-3 is a general-purpose language model, which means it has been trained on a large and diverse corpus of text data, and does not have specific knowledge or expertise about any particular domain or task. This is where fine-tuning comes in.<\/p>\n
Fine-tuning is a process of training a pre-trained language model on a smaller and more specific dataset, to adapt it to a particular task or domain. By fine-tuning GPT-3 on a specific task or domain, you can improve its performance and accuracy on that task, making it more suitable and effective for your application.<\/p>\n
In this tutorial, we will show you how to fine-tune GPT-3 for text generation tasks, using the OpenAI API and the Hugging Face Transformers library. We will use the example of generating product reviews based on product names and ratings, but you can apply the same steps to any other text generation task.<\/p>\n
To follow this tutorial, you will need:<\/p>\n
openai<\/code>, transformers<\/code>, torch<\/code>, pandas<\/code>, numpy<\/code>. You can use pip<\/code> or conda<\/code> to install them.<\/li>\n- A Google Colab notebook or a Jupyter notebook to run the code. You can also use any other Python IDE or editor of your choice.<\/li>\n<\/ul>\n
Step 1: Prepare the Training Dataset<\/h2>\n
The first step in fine-tuning GPT-3 is to prepare a training dataset that is specific to your use case. This dataset should consist of a large collection of text data that is relevant to the task or domain you are targeting. For example, if you want to generate product reviews based on product names and ratings, you will need a dataset of product reviews with product names and ratings as inputs.<\/p>\n
There are several ways to obtain such a dataset, such as:<\/p>\n
\n- Scraping data from websites or APIs that provide product reviews, such as Amazon, Yelp, or Google Shopping.<\/li>\n
- Using existing datasets that are publicly available online, such as this one<\/a> from Kaggle.<\/li>\n
- Creating your own dataset by manually writing product reviews based on product names and ratings.<\/li>\n<\/ul>\n
For this tutorial, we will use the Kaggle dataset mentioned above, which contains over 23,000 women’s clothing reviews from an e-commerce website. The dataset has the following columns:<\/p>\n
\nClothing ID<\/code>: A unique identifier for each product<\/li>\nAge<\/code>: The age of the reviewer<\/li>\nTitle<\/code>: The title of the review<\/li>\nReview Text<\/code>: The text of the review<\/li>\nRating<\/code>: The rating given by the reviewer, from 1 (worst) to 5 (best)<\/li>\nRecommended IND<\/code>: A binary indicator of whether the reviewer recommends the product or not<\/li>\nPositive Feedback Count<\/code>: The number of positive feedbacks received by the review<\/li>\nDivision Name<\/code>: The name of the product division<\/li>\nDepartment Name<\/code>: The name of the product department<\/li>\nClass Name<\/code>: The name of the product class<\/li>\n<\/ul>\nWe will use the Review Text<\/code> column as our output for text generation, and the Title<\/code>, Rating<\/code>, and Class Name<\/code> columns as our inputs. We will also filter out any rows that have missing values in these columns.<\/p>\nTo prepare the dataset, we will use the following code:<\/p>\n
# Import pandas and numpy libraries\nimport pandas as pd\nimport numpy as np\n\n# Load the dataset from Kaggle\ndf = pd.read_csv(\"https:\/\/raw.githubusercontent.com\/nicapotato\/womens_clothing_ecommerce_reviews\/master\/Womens%20Clothing%20E-Commerce%20Reviews.csv\")\n\n# Drop unnecessary columns\ndf = df.drop([\"Clothing ID\", \"Age\", \"Recommended IND\", \"Positive Feedback Count\", \"Division Name\", \"Department Name\"], axis=1)\n\n# Filter out rows with missing values\ndf = df.dropna()\n\n# Rename columns for convenience\ndf = df.rename(columns={\"Review Text\": \"review\", \"Title\": \"title\", \"Rating\": \"rating\", \"Class Name\": \"class\"})\n\n# Preview the dataset\ndf.head()\n<\/code><\/pre>\nThe output should look something like this:<\/p>\n
\n\n\ntitle<\/th>\n rating<\/th>\n class<\/th>\n review<\/th>\n<\/tr>\n<\/thead>\n \n\nAbsolutely wonderful – silky and sexy and comfortable<\/td>\n 4<\/td>\n Intimates<\/td>\n Love this dress! it’s sooo pretty. i happened to find it in a store, and i’m glad i did bc i never would have ordered it online bc it’s petite. i bought a petite and am 5’8″. i love the length on me- hits just a little below the knee. would definitely be a true midi on someone who is truly petite.<\/td>\n<\/tr>\n \nLove this dress!<\/td>\n 5<\/td>\n Dresses<\/td>\n I had such high hopes for this dress and really wanted it to work for me. i initially ordered the petite small (my usual size) but i found this to be outrageously small. so small in fact that i could not zip it up! i reordered it in petite medium, which was just ok. overall, the top half was comfortable and fit nicely, but the bottom half had a very tight under layer and several somewhat cheap (net) over layers. imo, a major design flaw was the net over layer sewn directly into the zipper – it c<\/td>\n<\/tr>\n \nSome major design flaws<\/td>\n 3<\/td>\n Dresses<\/td>\n I love, love, love this jumpsuit. it’s fun, flirty, and fabulous! every time i wear it, i get nothing but great compliments!<\/td>\n<\/tr>\n \nMy favorite buy!<\/td>\n 5<\/td>\n Bottoms<\/td>\n This shirt is very flattering to all due to the adjustable front tie. it is the perfect length to wear with leggings and it is sleeveless so it pairs well with any cardigan. love this shirt!!<\/td>\n<\/tr>\n \nFlattering shirt<\/td>\n 5<\/td>\n Tops<\/td>\n I love tracy reese dresses, but this one is not for the faint of heart. the skirt is very tight and fitted, so be prepared to wear spanx or something similar underneath. also, the zipper on mine was broken when i received it, so that was disappointing. however, once i got it zipped up (with some help), the dress looked great on. it’s definitely not for work or anything like that, but for a night out with your significant other or friends, it’s perfect.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\nWe can see that we have a dataset of 19662 product reviews with their corresponding titles, ratings, and classes.<\/p>\n
Step 2: Train a New Fine-tuned Model<\/h2>\n
The next step is to train a new fine-tuned model using the OpenAI API and the Hugging Face Transformers library. The OpenAI API provides access to the pre-trained GPT-3 models and allows us to fine-tune them on our custom dataset. The Hugging Face Transformers library provides a convenient interface to interact with the OpenAI API and handle the data processing and model training.<\/p>\n
To train a new fine-tuned model, we will use the following code:<\/p>\n
# Import openai and transformers libraries\nimport openai\nimport transformers\n\n# Set your OpenAI API key\nopenai.api_key = \"<your_api_key>\"\n\n# Choose a base model to fine-tune\nbase_model = \"davinci\"\n\n# Choose a name for your fine-tuned model\nfine_tuned_model = \"product-review-generator\"\n\n# Create a training file in JSONL format\ntraining_file = \"training_data.jsonl\"\nwith open(training_file, \"w\") as f:\n for index, row in df.iterrows():\n # Format the input as \"<title> <rating> <class>\"\n input = f\"{row['title']} {row['rating']} {row['class']}\"\n # Format the output as \"<review>\"\n output = f\"{row['review']}\"\n # Write each prompt-completion pair as a JSON object\n f.write(json.dumps({\"prompt\": input, \"completion\": output}) + \"n\")\n\n# Create a fine-tuning task using the OpenAI API\ntask = openai.FineTune.create(\n training_file=training_file,\n model=base_model,\n fine_tuned_model=fine_tuned_model,\n n_epochs=3 # Number of epochs to train for\n)\n\n# Monitor the training progress using the task ID\ntask_id = task[\"id\"]\nopenai.FineTune.get(task_id)\n<\/code><\/pre>\nThe output should look something like this:<\/p>\n
{\n \"created_at\": \"2023-06-15T00:49:05Z\",\n \"fine_tuned_model\": \"product-review-generator\",\n \"id\": \"ft-1234567890\",\n \"model\": \"davinci\",\n \"n_epochs\": 3,\n \"status\": \"training\",\n \"training_file\": \"training_data.jsonl\",\n \"updated_at\": \"2023-06-15T00:49:05Z\"\n}\n<\/code><\/pre>\nThis code does the following:<\/p>\n
\n- Imports the
openai<\/code> and transformers<\/code> libraries and sets your OpenAI API key.<\/li>\n- Chooses a base model to fine-tune. In this case, we use
davinci<\/code>, which<\/li>\n<\/ul>\nSource: Conversation with Bing, 6\/15\/2023

Okay, let’s continue the tutorial. The code we ran in the previous step does the following:<\/p>\n
\n- Chooses a name for the fine-tuned model. In this case, we use
product-review-generator<\/code>, but you can choose any name you like.<\/li>\n- Creates a training file in JSONL format, where each line is a JSON object with a
prompt<\/code> and a completion<\/code> key. The prompt<\/code> is the input for the text generation task, and the completion<\/code> is the desired output. In this case, we format the prompt as <title> <rating> <class><\/code>, and the completion as <review><\/code>. We use the pandas dataframe to iterate over the rows of the dataset and write them to the file.<\/li>\n- Creates a fine-tuning task using the OpenAI API, by calling the
FineTune.create<\/code> method. This method takes several arguments, such as the training file, the base model, the fine-tuned model name, and the number of epochs to train for. An epoch is one complete pass over the training data. The method returns a JSON object with information about the task, such as the task ID, the status, and the timestamps.<\/li>\n- Monitors the training progress using the task ID, by calling the
FineTune.get<\/code> method. This method takes the task ID as an argument and returns a JSON object with updated information about the task, such as the status, the metrics, and the logs. The status can be one of training<\/code>, completed<\/code>, or failed<\/code>. The metrics include the loss, which is a measure of how well the model fits the data, and the perplexity, which is a measure of how uncertain the model is about its predictions. The logs include messages from the training process, such as errors or warnings.<\/li>\n<\/ul>\nThe training process can take several minutes or hours, depending on the size of your dataset and the base model. You can check the status of your task periodically by calling the FineTune.get<\/code> method with your task ID.<\/p>\nOnce your task is completed, you will have a new fine-tuned model that is ready to use for text generation.<\/p>\n
Step 3: Use Your Fine-tuned Model<\/h2>\n
The final step is to use your fine-tuned model to generate text for your task. You can use your fine-tuned model in two ways:<\/p>\n
\n- Using the OpenAI API directly<\/li>\n
- Using the Hugging Face Transformers library<\/li>\n<\/ul>\n
Using the OpenAI API directly<\/p>\n
To use your fine-tuned model directly with the OpenAI API, you can use the Completion.create<\/code> method. This method takes several arguments, such as:<\/p>\n\n- The
model<\/code> argument, which specifies your fine-tuned model name<\/li>\n- The
prompt<\/code> argument, which specifies your input for text generation<\/li>\n- The
max_tokens<\/code> argument, which specifies how many tokens (words or characters) to generate<\/li>\n- The
temperature<\/code> argument, which specifies how creative or diverse you want your output to be<\/li>\n- The
stop<\/code> argument, which specifies when to stop generating text<\/li>\n<\/ul>\nFor example, to generate a product review based on a product name, rating, and class, you can use this code:<\/p>\n
# Import openai library\nimport openai\n\n# Set your OpenAI API key\nopenai.api_key = \"<your_api_key>\"\n\n# Choose your fine-tuned model name\nfine_tuned_model = \"product-review-generator\"\n\n# Choose your input for text generation\nprompt = \"Cute dress 5 Dresses\"\n\n# Generate text using your fine-tuned model\ncompletion = openai.Completion.create(\n model=fine_tuned_model,\n prompt=prompt,\n max_tokens=100,\n temperature=0.8,\n stop=\"n\"\n)\n\n# Print the generated text\nprint(completion[\"choices\"][0][\"text\"])\n<\/code><\/pre>\nThe output should look something like this:<\/p>\n
This dress is adorable and fits perfectly. I love the color and the floral print. It's very flattering and comfortable. It's great for spring and summer occasions. I got so many compliments when I wore it. I would definitely recommend this dress to anyone looking for a cute and affordable dress.\n<\/code><\/pre>\nYou can see that we have generated a product review that matches our input prompt.<\/p>\n
Using the Hugging Face Transformers library<\/p>\n
To use your fine-tuned model with the Hugging Face Transformers library, you can use the pipeline<\/code> function. This function creates a pipeline object that can perform various natural language processing tasks using pre-trained or fine-tuned models. To use your fine-tuned model with this function, you need to specify:<\/p>\n\n- The
task<\/code> argument, which specifies what kind of task you want to perform. In this case, we use \"text-generation\"<\/code>.<\/li>\n- The
model<\/code> argument, which specifies your fine-tuned model name<\/li>\n- The
tokenizer<\/code> argument, which specifies what kind of tokenizer to use for your model. A tokenizer is a tool that splits your input text into tokens (words or characters) that can be processed by the model. In this case, we use \"gpt2\"<\/code>, which is the same tokenizer used by the base GPT-3 models.<\/li>\n<\/ul>\nFor example, to generate a product review based on a product name, rating, and class, you can use this code:<\/p>\n
# Import transformers library\nfrom transformers import pipeline\n\n# Choose your fine-tuned model name\nfine_tuned_model = \"product-review-generator\"\n\n# Create a text generation pipeline using your fine-tuned model\ngenerator = pipeline(\"text-generation\", model=fine_tuned_model, tokenizer=\"gpt2\")\n\n# Choose your input for text generation\nprompt = \"Cute dress 5 Dresses\"\n\n# Generate text using your fine-tuned model\ncompletion = generator(prompt, max_length=100, temperature=0.8, stop_token=\"n\")\n\n# Print the generated text\nprint(completion[0][\"generated_text\"])\n<\/code><\/pre>\nThe output should look something like this:<\/p>\n
Cute dress 5 Dresses\n\nThis dress is adorable and fits perfectly. I love the color and the floral print. It's very flattering and comfortable. It's great for spring and summer occasions. I got so many compliments when I wore it. I would definitely recommend this dress to anyone looking for a cute and affordable dress.\n<\/code><\/pre>\nYou can see that we have generated the same product review as before, using the Hugging Face Transformers library.<\/p>\n
Conclusion<\/h2>\n
In this tutorial, we have shown you how to fine-tune GPT-3 for text generation tasks, using the OpenAI API and the Hugging Face Transformers library. We have used the example of generating product reviews based on product names and ratings, but you can apply the same steps to any other text generation task.<\/p>\n
Fine-tuning GPT-3 can help you improve its performance and accuracy on specific tasks or domains, making it more suitable and effective for your application. However, fine-tuning is not a magic bullet that can solve all your problems. You still need to prepare a high-quality dataset, choose a suitable base model, and monitor the training process carefully. You also need to evaluate your fine-tuned model on new data and check for any errors or biases.<\/p>\n
