With 40% of global companies now using AI, new data reveals that businesses need to consider how these tools differ from one another and what that means for the workplace.
Research from Online DISC Profile has determined that Large Language Models (LLMs) each possess a different personality type, meaning that responses or written copy will differ in tone depending on the LLM used, which might then differ from what the user intended.
The personality that has been determined for each LLM is the DISC type, which Online DISC Profile offers assessments so people can understand their behavioral preferences, traits, communication style and ideal work environments.
Gemini, Perplexity, CoPilot, DeepSeek and ChatGPT were put to the same test, meaning you can determine the tone of messaging you’ll get, any authoritativeness in its answers or whether it’s a “good listener”.

What does this mean for the workplace?
With this new data showing LLMs having differing personality types, it highlights that employees need to check that the tone coming from these platforms aligns with what they intend, or else it could be misinterpreted.
Adam Stamm, co-owner of Online DISC Profile, says: “It also comes down to the amount of editing you do as well, no one should take what an LLM writes as verbatim and run with it – always edit what comes from these sources.”
If your workplace only has access to one LLM, like ChatGPT, and you don’t want the tone of your work to come across too direct, consider training it so it aligns more to your style. Workplaces will have a mixture of personality types, and you would adapt communication styles to align, so training LLMs would be no different.
As with all AI tools, you have to be careful with usage and always check any information it gives you. The danger of these tools being able to adapt to any personalities increases the risk of people creating “fake personas”, which could be used in workplace settings.
Someone could use an LLM to draft a job application in a style completely different to theirs, reach the interview stage where they then appear completely different and result in wasted time and money for both parties.
If used correctly, these tools can help workplaces on a variety of important tasks, such as training new employees. And if you consider a person’s DISC type, you can use the matching tool to help deliver work in the right tone and style.
