The development of artificial intelligence (AI) systems that can converse with humans in natural language has progressed rapidly in recent years. Advanced AI chatbots utilize machine learning models called language models to generate human-like text responses to questions and conversations.

Two of the most advanced chatbots that have emerged are ChatGPT, created by the research company OpenAI, and Bard, developed by Google. ChatGPT was released to the public in late 2022 while Bard was announced in February 2023 as Google’s response to the popularity of ChatGPT. Both chatbots demonstrate the immense progress that has been made in natural language processing and the potential for AI to have human-like conversational abilities.

ChatGPT and Bard represent a new generation of chatbots that are powered by large language models trained on massive amounts of text data from the internet. This training enables the AI models to generate coherent, nuanced, and seemingly intelligent responses on a wide range of topics when prompted with natural language questions and conversation. The goal with both ChatGPT and Bard is to create conversational AI assistants that can be helpful, harmless, and honest.

ChatGPT Overview

ChatGPT is a generative artificial intelligence system created by Anthropic, an AI safety startup based in San Francisco. It was released to the public in November 2022 and quickly gained widespread popularity due to its advanced conversational abilities.

ChatGPT is powered by a large language model that was trained on vast amounts of text data from the internet. This allows it to generate human-like responses on a wide range of topics in a conversational manner. Users can interact with ChatGPT by giving it natural language prompts, to which it will respond in paragraph-form.

Some key capabilities of ChatGPT include:

• Conversing coherently on open-ended topics
• Answering follow-up questions and adjusting responses based on new information
• Explaining concepts simply and generating content on demand
• Admitting mistakes and rejecting inappropriate requests

Despite its impressive language skills, ChatGPT does have some limitations. It lacks common sense and doesn’t have true comprehension. All of its knowledge comes from training data up to 2021, so it lacks current real-world knowledge. It may also occasionally generate false information or biased responses.

Overall, the launch of ChatGPT represents a major advancement in AI’s language and reasoning abilities. Its conversational nature and versatility make it an exciting new tool, although users should be aware of its limitations.

Bard Overview

Bard is an experimental conversational AI service created by Google. It was announced in February 2023 as Google’s rival to ChatGPT.

Bard aims to provide helpful, high-quality information to users through natural conversations. It utilizes Google’s own language model called LaMDA (Language Model for Dialogue Applications). This allows Bard to understand complex contexts and generate responses based on its training data.

Unlike ChatGPT which is owned by OpenAI, Bard is designed and built solely by Google. The company highlighted Bard’s ability to leverage information from the internet to provide up-to-date responses. During the launch announcement, Google CEO Sundar Pichai stated that Bard will combine the breadth of world knowledge with the power, intelligence and creativity of Google’s language models.

Bard is currently being tested internally at Google. The company plans to open it up to trusted external testers soon before making it more widely available to the public later in 2023. Google has positioned Bard as central to the future of its business, touting it as its AI chatbot that can have natural conversations on any topic.

Language Model

ChatGPT and Bard rely on fundamentally different language models. ChatGPT uses GPT-3, an autoregressive language model developed by OpenAI. GPT-3 has over 175 billion parameters and was trained on a massive dataset of online text. This allows it to generate remarkably human-like text by predicting the next word in a sequence based on the previous words.

In contrast, Bard uses LaMDA (Language Model for Dialogue Applications), Google’s own language model designed specifically for dialogue. LaMDA has over 130 billion parameters and was trained not just on text but also conversational data. This allows it to have more natural conversations. While GPT-3 aims to generate any type of text, LaMDA is focused on dialogue.

The different underlying language models contribute to differences in capabilities between ChatGPT and Bard. GPT-3’s strength lies in long-form text generation while LaMDA aims to have more natural, contextual conversations. It remains to be seen which approach will prove more capable over time. But the language model is central to how these AI systems operate.

Knowledge Base

ChatGPT was trained on data across the internet up until 2021. This gives it an extensive foundation of knowledge on topics ranging from pop culture to science and technology. However, since the model is not being updated, its knowledge base is fixed as of 2021.

Bard, on the other hand, has been trained on more recent data across the web. This gives Bard an advantage in terms of understanding the latest topics, events, and information across domains. While the details of Bard’s training data are not fully disclosed, it likely includes data from 2022 and potentially into 2023. This means Bard may have stronger knowledge about emerging topics like ChatGPT itself, new AI systems, crypto/Web3 trends, and other recent events.

The recency of Bard’s training data gives it an edge for questions and conversations about the present day. However, ChatGPT’s extensive foundation on data through 2021 grants it in-depth knowledge that may sometimes surpass Bard, depending on the topic. Both models have strengths and weaknesses in their knowledge that stem from their different training periods.

Capabilities

ChatGPT and Bard have some overlapping capabilities, but also differ in key areas based on their underlying AI models.

ChatGPT has demonstrated extremely strong natural language text generation abilities. It can understand prompts and contexts, then generate coherent and fluent text responses on a wide array of topics. This includes conversational responses, explanatory texts, creative writing samples, code generation, and more. However, the tradeoff is that ChatGPT sometimes generates plausible-sounding but incorrect or nonsensical responses. It does not have a robust mechanism for checking facts.

In contrast, Bard aims to provide more accurate and factual responses by incorporating additional knowledge sources. Google states Bard is designed to combine the breadth of the web with the depth, nuance and factual grounding of high-quality reference materials. Early tests indicate Bard exhibits stronger factual accuracy compared to ChatGPT, but may have some limitations around creative text generation.

So in summary, ChatGPT leads in natural language prowess and text generation capabilities, while Bard aims to harness knowledge from the web and vetted sources to provide more useful, factual responses. Both have advantages and disadvantages that may make one better suited than the other depending on the use case.

Limitations

Despite the impressive capabilities of ChatGPT and Bard, they do have limitations. As AI systems, they face issues with factual accuracy. Neither current system can be fully trusted as an authority on factual information. Their knowledge comes from analyzing available data, but there will naturally be gaps that lead to incorrect or biased responses. Even with the most advanced content filters, some inaccurate or biased information can slip through.

For example, some of ChatGPT’s responses may rely on outdated sources and present out-of-date facts as current. Other responses can seem certain of an answer when the system actually lacks the full context to make such an assertion. Both systems may exhibit biases from their training data as well. This is especially concerning for sensitive topics related to race, gender, politics and more. Neither AI can necessarily override harmful stereotypes and assumptions that exist in the available data.

In summary, users should be aware that while ChatGPT and Bard can offer conversational explanations on many topics, they do not possess true understanding. Their knowledge consists of patterns from data, not lived experience and critical thinking skills. So while these AI can offer useful information, they cannot be fully relied upon for complete accuracy and neutral perspectives. Human oversight is still required to catch potential factual errors, logical inconsistencies, and biased assertions. More work is needed to improve the factual diligence and ethical alignment of such AI systems.
