Introduction

The landscape of AI assistant "co-pilots" is rapidly evolving, with major updates for Google's Bard and Anthropic's Claude 2 in the last week. AI copilots are becoming indispensable tools for everyday tasks, ranging from quick knowledge searches to longer writing endeavors. In this blog, I'll explore and the four leading AI copilots: ChatGPT, Bing AI, Google Bard, and Claude 2. To provide a comprehensive evaluation, I complimented my own research with asking each chatbot to pitch why they are the best AI co-pilot.

Prompt: Give me a short pitch why X is the best AI co-pilot chatbot to use in day to day compared to others on the market (Claude, ChatGPT, Google Bard). Make this pitch in the form of concise bullet points. Highlight unique features that X has that the competitors do not.Include technical information about that X has been trained on and why this is advantageous.

ChatGPT

Chatbot GPT-3.5, also known as ChatGPT (the OG), is an AI language model developed by OpenAI. It is designed to engage in natural language conversations with users, providing human-like responses and generating coherent text on various topics. It was trained on a dataset of 175 billion parameters (570GB of text data).

Pros

• Familiar UX: Enabling you easily separate and save conversations, and edit & regenerate prompts.
• Rich API Integration: ChatGPT offers a seamless integration with a wide array of applications.

Cons

• Out of date: training data only up to 2021.
• Writing Style: Given popularity, its writing style can be identifiable.

‍

Bing AI

Bing AI is a chat mode of Microsoft Bing Search that can understand and communicate fluently in the user’s language of choice. It can also generate content such as poems, stories, and articles (not this one, I promise).

Pros

• Web Search: Bing AI can search the web, and will provide citations from sources for its answers, enabling you to quickly go one level deeper
• Excellent UX: When working in Microsoft edge, Bing sits on the right of your screen for easy access
• Up-to-date model: Bing AI is powered by GPT-4, trained on over 500 billion words from the web, books, news, and social media.
• Bing was the most accurate and concise in answering my prompt

Cons

• Reference: Bing does not save conversations in an easily reviewable format.
• Character limit: Bing has a 2000 character limit for generations.

‍

Google Bard

Bard is a large language model (LLM) developed by Google AI. It can be used for a variety of tasks, including generating text, translating languages, and answering your questions. Bard was trained on 187 billion parameters, 50% of which was dialogue information from public forum, and the remainder from Wikipedia and the web.

Pros

• Integration with Google Lens: Enabling some amazing use cases from uploading images, including i) Upload a picture of a product and ask Bard to shop and find the best deal online; Upload a picture of a landmark, and Bard will identify it, and give you its history and context; iii) Upload a picture of a plate of food and get the recipe
• Voice controlled: You can use the microphone to speak, and listen back your response
• Export Integrations: You can export and  share conversations via google docs, sheets, or Gmail drafts

Cons

• Google Bard gave the most generic response to my prompt out of all the chat bots. Its response also did not highlight the above unique features.

‍

Claude 2

Claude 2 is an AI assistant created by Anthropic. The goal of Claude 2 is to have natural conversations while avoiding harmful responses.

Pros

• Natural Langue: Claude’s writing style is the most human like
• Conversation Length: Claude can handle inputs and conversations up to 75k words, vs 24k words of ChatGPT
• Up-to-date: Claude 2’s training data cut off is early 2023
• You can upload and analyse files

Cons

• UX: Frustratingly, you can't stop and edit prompts mid generation
• Whilst well written, Claude’s response to my prompt were generic, and did not capture the above points

‍

Conclusion

For quick and accurate knowledge searches, Bing AI is my preference with its superior UX integrated into Microsoft edge and reliable, cited information. For longer writing tasks, Claude 2's natural language quality makes it the preferred choice, despite a less friendly UX than ChatGPT. However, the AI copilot that shows immense potential for the future is Google Bard, thanks to its integration with Google Lens and wider Google suite of tools, offering a plethora of use cases and seamless user experience. Given Google's deep pockets, existing suite of free tools and real ambition to dominate in this space, I would imagine Bard to keep on improving to eventually be the default choice in the future.
