Copilot vs ChatGPT: An Experiment 

To explore how different AI tools can assist in work tasks, we conducted a couple of experiments comparing Copilot and ChatGPT. Our goal was to understand how each tool interprets instructions, generates outputs, and potentially impacts productivity.

Experiment one: Draw a Square 

We started by asking both ChatGPT and Copilot to draw a square, and the results were quite different. 

ChatGPT: 

Co-Pilot:

Conclusion

When we asked Co-pilot to draw a square, it created an actual graphic image of a square,  a visual, downloadable picture.  ChatGPT, on the other hand, interprets the request in a text or code-based way, producing a square made of characters (ASCII art) instead of a real image. 

Experiment Two: Automating Tasks 

Our next experiment was to see how AI could help automate tasks and improve employee productivity. We asked both AI models to draft a potential email to a client, informing them about the status of their IT services, including any scheduled maintenance, system upgrades, or unexpected outages.

ChatGPT:

Co-Pilot: 

Conclusion

The two draft emails differ in tone, structure, and level of detail. The first email from ChatGPT is a straightforward scheduled maintenance notice, brief, formal, and focused solely on informing the client of a specific service interruption. It lacks personalisation, offering only a general invitation to reach out.

The second email from Co-pilot is more detailed and client-friendly. It includes a clear call to action and provides full contact information. This level of detail makes it easier for clients to follow up and reinforces transparency and trust.

Experiment Three: 

Our final experiment was to ask both AI models to summarise one of our most recent blog posts on the Halcyon website. Here is what each model returned: 

ChatGPT:

Co-Pilot:

Conclusion

Both blog summaries outline the differences between OneDrive and SharePoint, but they vary in depth and presentation. The first summary from ChatGPT offers a structured breakdown of features, use cases, and implementation tips, making it ideal for readers who prefer a more analytical overview.

The second summary is more visual and concise, using icons and bullet points to highlight key distinctions and support options. It focuses on practical advice and quick takeaways, making it more digestible for busy readers. Overall, the first is more detailed and strategic, while the second is punchier and action-oriented.

Limitations and Concerns of AI

While AI offers powerful capabilities, it also comes with limitations and concerns that users should be aware of. Accuracy remains a major issue, as AI can produce incorrect or misleading information, making human verification important.. AI models do not truly understand context, so nuanced tasks or complex reasoning can be misinterpreted.

AI tools can also introduce cybersecurity risks, such as exposing systems to attacks if vulnerabilities in AI applications are exploited or if sensitive data is handled insecurely. Businesses should assess these risks carefully and consider strong cybersecurity measures.

Bias is another concern. AI can reflect and amplify biases present in its training data, leading to unfair outcomes. Other challenges include ethical and legal questions, such as content ownership and accountability, as well as the potential for over-reliance, which can reduce human skill development. Running advanced AI models can also be costly and resource-intensive, limiting access for smaller businesses or individuals.
