Model Architecture and Training
Understanding the architecture and training methodologies of AI models is crucial for appreciating their capabilities and potential applications. Let's take a closer look at the inner workings of ChatGPT and Bard.
ChatGPT Architecture and Training
ChatGPT is built on a transformer-based model, a type of model architecture that has revolutionized the field of Natural Language Processing (NLP). Transformer models, introduced by Vaswani et al. in their paper "Attention is All You Need", use a mechanism called 'attention' to understand the context and generate responses.
The attention mechanism allows the model to focus on different parts of the input when generating each word in the output. This enables the model to generate highly coherent and contextually relevant text, a key feature of ChatGPT.
Training of ChatGPT is carried out in two main steps: pretraining and fine-tuning. During pretraining, the model is exposed to a vast corpus of text data from the internet, learning to predict the next word in a sentence given the previous words. This forms the model's base knowledge.
In the fine-tuning stage, the model is further trained on a narrower dataset, generated with the help of human reviewers following specific guidelines provided by OpenAI. This process helps the model to refine its responses, ensuring it adheres to a set of ethical and policy guidelines.
Bard Architecture and Training
Like ChatGPT, Bard also utilizes a transformer-based model architecture, capitalizing on the advantages of the attention mechanism to generate detailed narratives. Google has introduced unique enhancements to this architecture, optimizing it for narrative generation. The specifics of these modifications, however, are proprietary to Google and not publicly available.
The training methodology of Bard is also not fully disclosed. However, it's known that Google uses a combination of supervised and unsupervised learning techniques, leveraging its vast datasets to optimize the performance of Bard.
In supervised learning, the model is trained on a dataset where the 'correct' answers are already known, allowing the model to learn by comparing its output to the correct output. In unsupervised learning, the model is given unlabelled data and must find patterns and relationships within the data on its own.
These training methodologies allow both ChatGPT and Bard to not only understand and generate human-like text but also demonstrate a certain level of 'creativity' in their responses. In the following sections, we will discuss the capabilities and applications of these models, their limitations, and ethical considerations.

Real World testing and comparison
When using new technologies it is important to test them better understand both their strengths and weaknesses. This helps you choose which system to utilize for the tasks you are performing, providing you the best outcomes.
Content Structuring
The first test I ran both ChatGPT and Bard through was to create a blog structure that could be used in creating a blog post.
To test each systems ability to create a blog structure I used the following prompt: Write a blog structure over the current state of AI.
Both AI technologies provide a sound blog structure over the current state of AI. There were some similarities between the topics with a few deviations. All in all they both provided a structure that could be turned into an engaging and informative blog post.
Context Retention
Now to continue testing I wanted to see the ability of each system to pivot off of their previous answer and create an introduction using the previous structure and bullet points. This test would show the ability of these AI system to perform a more conversational interaction when creating content.
I created the following prompt to see if each system could create an introduction:
Using the introduction bullet points create a full introduction for this blog post.
ChatGPT was able to create a full introduction for the blog post using the previously provided introduction structure.
Bard was not able to use its own previously provided introduction structure to create an introduction. Instead of having Bard use its own previous answers to create the introduction it was necessary to create a new prompt so that Bard would create the needed introduction.
Content Creation
Since we were able to create blog structures and introductions now I wanted to see if each system could create an entire blog post using the following prompt:
Write a blog over the current state of AI.
Both ChatGPT and Bard were able to write a complete blog article, while there were some similar topics in both articles and the structure was similar I felt that ChatGPT went into more detail than Bard did. Both systems talked about the benefits and cited some drawbacks to the use of AI. Bard dove into some privacy and warfare topics while ChatGPT seemed to talk about replacing people’s jobs with AI.
Social Media Posts
Moving on from blog creation I want to move into social media, specifically Instagram and Twitter since there are usually some constraints around writing posts for these platforms.
I asked both systems to create an instagram post about the brand new Samsung Z Fold 5 which just came out in 2023 using the following prompt:
Create an Instagram post over the Samsung Z Fold 5.
ChatGPT was able to create an instagram post but the post was pretty generic mostly due the data used to train the AI. ChatGPT is only trained on data up to September of 2021 and the new Z Fold 5 was released in 2023.
Bard was able to create a much better Instagram post with detailed information on the Z Fold 5 since it is continually updated almost real time. This data provided a much more accurate post that readers would be interested in.
Now we pivoted to Twitter, this social media platform as a stricter character limit, to test each system's ability to create an engaging post while adhering to the limits. I used the same prompt as I did for Instagram.
Create a Twitter post over the Samsung Z Fold 5.
ChatGPT was able to create a twitter post but again it was pretty generic due to the outdated data that ChatGPT is trained on. The post was within Twitter's character limits and I didn’t have to make any changes to the prompt before posting it on Twitter.
Bard missed the mark on keeping the post that was based on the same prompt within the character limits. This was easily overcome by modifying the prompt to the following.
Create a Twitter post over the Samsung Z Fold 5 keeping it within the twitter character limit.
Once I added the extra criteria to keep the post within Twitter’s character limit, not only did Bard create an acceptable post but also provided the limits and a character count of the tweet it created. As before there were more accurate details about the Z Fold 5 that ChatGPT wouldn’t know about.
Code Writing
Moving on to other skills that these AI systems have that can assist in tasks such as writing Code. To test the code writing abilities of both systems I used the following prompt asking each system to create a python script that would pull weather data from an api and display it.
Create a python program that will call the OpenWeather API, pull down the latest weather and print them in an easy to read format.
Both systems were able to create a python script that would use the OpenWeather API to pull weather data. Both systems also provided an example of how to use the code but Bard went as far as to show what the output of the data would look like if you ran the code. Outside of that extra touch both programs were usable and correct. Both ChatGPT and Google’s Bard systems provided code that was pretty much exactly the same.
ChatGPT Python Code
Realtime Questions
Now to put the two AI systems to the test by asking a question requiring up to date information. To do this I used the following prompt:
What is the release date of the Samsung Galaxy Watch 6?
ChatGPT was unable to provide information and instead displayed the disclaimer that the last data update was September of 2021.
ChatGPT failed to answer
Bard was able to provide a release date and a pre-order data along with model information and details about the watch.
This question highlighted a drawback in using ChatGPT for certain prompts or when looking for specific information that is after the 2021 cutoff date.
Conclusions
In the comparison of the two artificial intelligence systems' capabilities in terms of content creation, code generation, and question answering, both have demonstrated commendable competence. However, discernible limitations could guide users in choosing a system depending on the particular task at hand.
Both systems have shown capacity to generate satisfactory content, provided that the subject matter predates September 2021. Notably, the usability of ChatGPT tends to surpass that of Bard due to its capacity for context retention, allowing users to pose follow-up questions and receive responses based on the ongoing conversation. Conversely, with Bard, a consistent restatement of the prompt is necessary for the system to deliver the requisite information.
As for the generation of code, both systems demonstrated equivalent performance, producing practically identical results.
When the AI systems were tested on their ability to craft social media posts, they each successfully generated content suitable for platforms like Instagram and Twitter. Provided that the subject matter is within ChatGPT's knowledge cut-off, both systems will yield adequate content. For instance, when tasked to create a post about the new Samsung Z Fold 5, Bard was able to produce a detailed post, while ChatGPT, constrained by its knowledge cut-off, had to generate a more generic post.
Lastly, in terms of retrieving specific information, such as the release date for the Samsung Watch 6, Bard proved superior. ChatGPT failed to produce a response, while Bard was able to provide not only the release date, but also pre-order data and additional details about the product.
