Why Google Bard is Inferior to Open AI’s ChatGPT: Personas and Imagination

Artificial Intelligence (AI) is an ever-evolving field, with tech giants like Google and OpenAI leading the charge in innovation. Both have developed state-of-the-art language models – Google’s Bard and OpenAI’s ChatGPT – that are capable of generating human-like text. While both are groundbreaking in their own ways, there is a key factor that sets them apart: the power of imagination.


In this context, imagination refers to the ability of a language model to adapt its responses based on specific characters, or ‘personas’, and to be fine-tuned for different tasks or domains. While both models possess remarkable language generation capabilities, it is ChatGPT’s ability to imagine – to take on personas and fine-tune its responses – that gives it the upper hand over Google’s Bard.


In this article, we will delve into why this is the case, and how this “lack of imagination” in Google Bard impacts its overall effectiveness when compared to ChatGPT.

Understanding the Power of Personas

The concept of ‘personas’ in AI language models refers to a set of characteristics or attributes that guide the model’s behavior and responses. As we discussed in our previous blog post, a well-crafted persona can dramatically enhance the interaction quality with an AI, making it more relatable, engaging, and personalized.


But why is this concept so powerful? Simply put, personas allow a language model to become an expert in virtually any field. Whether you need a trivia guru, a financial advisor, or a creative story writer, the skillset defined in the persona will shape the expertise of your AI model.



This ‘imagination’ empowers AI language models like ChatGPT to adapt their responses according to the persona’s background, personality, skillset, likes, and dislikes, hence creating a more context-aware and expert-like user experience.


On the contrary, the lack of this imaginative ability in Google Bard hinders its flexibility and adaptability, limiting its use-cases and overall effectiveness.

ChatGPT’s Fine-Tuning Flexibility and Bard’s Lack of Imagination

Fine-tuning is the process of training a pre-trained language model on a specific task or domain. In essence, it refines the model’s responses to be more accurate and applicable to the task at hand. The extent to which a model can be fine-tuned is often a key determinant of its utility and versatility.



OpenAI’s ChatGPT stands out in this regard, exhibiting a remarkable level of flexibility in fine-tuning. ChatGPT can be meticulously fine-tuned for various tasks including language translation, summarization, text completion, and persona embodiment. This means that ChatGPT can be calibrated to “become” a specific persona, assuming traits, skillsets, and backgrounds that enhance the AI’s interaction with users. This ability creates a more immersive, engaging, and personalized user experience.


Contrastingly, Google Bard, despite being a robust AI model, has significant limitations in terms of fine-tuning and persona creation. Bard is specifically designed for sequence-to-sequence tasks, such as language translation, text summarization, and text generation. Unlike ChatGPT, Bard cannot assume personas or be fine-tuned beyond these initial tasks.


This limitation leads to a significant shortcoming in Bard: a lack of imagination. Bard’s inability to adopt a persona affects its capacity to provide personalized, context-aware responses. Without the ability to ‘become’ a character or an expert in a specific field, Bard’s interactions are more generic and less engaging.



Moreover, Bard lacks the robustness in managing long conversations, maintaining context, and adapting to changing prompts – capabilities at which ChatGPT excels. This distinction is critical when creating an AI model that can engage in dynamic, context-aware interactions, serving as a personal assistant, an expert advisor, or an entertaining conversationalist.

Expert Personas in ChatGPT Vs. Google Bard

To fully illustrate the difference between ChatGPT and Google Bard, let’s explore a hypothetical scenario.

Imagine a user wants to interact with an AI model that embodies a persona of a seasoned financial analyst. This ‘analyst’ would need to understand intricate financial terminologies, possess knowledge about market trends, and give advice on financial planning and investment strategies. Furthermore, to be truly engaging, the persona should be able to maintain a professional, yet friendly tone, provide personalized responses, and sustain a consistent interaction over time.

Creating a Financial Analyst Persona with ChatGPT

With ChatGPT, the creation of this persona is achievable. ChatGPT can be fine-tuned to embody a financial analyst’s persona, with all the necessary knowledge and skills. Through careful prompt design and persona traits specification, ChatGPT can be guided to respond accurately to financial queries, emulate the professional tone, and even remember past interactions for a consistent user experience. Thus, the user receives expert, personalized advice in an engaging and consistent manner.

The Bard Experience

Conversely, when we try to create a similar persona with Google Bard, we face challenges. Bard, while able to respond to financial queries owing to its pre-trained language model, lacks the ability to ’embody’ the persona of a financial analyst. The responses, while factual, may lack the professional tone, the personalized advice, and the ability to maintain consistency across multiple interactions. Moreover, Bard struggles with long conversations and adapting to changing prompts, which further hampers its capacity to serve as a personal financial advisor.

Whether serving as a personal assistant or an expert advisor, ChatGPT’s imaginative power makes it a versatile and powerful tool in the realm of AI language models.

Why Imagination Matters in AI

In a world increasingly reliant on artificial intelligence, the ability of an AI model to “imagine,” to embody a persona, and to fine-tune its responses is not just an interesting feature—it’s a game changer.


This imaginative capacity, embodied by OpenAI’s ChatGPT, allows for more engaging, personalized, and expert-level interactions, significantly enhancing the user experience. Through careful fine-tuning and the strategic implementation of personas, ChatGPT transcends the limitations of a conventional AI language model, evolving into a tool that can cater to diverse requirements across various domains.


While Google Bard is a formidable AI model in its own right, its limitations become apparent when it comes to the creative and dynamic aspects of persona creation. Bard’s difficulty with long conversations, adaptability to changing prompts, and most importantly, its lack of ability to “embody” a persona, highlight its shortcomings in comparison to ChatGPT.


In the end, it’s clear that the future of AI language models is not just about information processing or task completion—it’s about creativity, adaptability, and imagination. And it’s in these areas that OpenAI’s ChatGPT truly shines, paving the way for a new era of artificial intelligence.
