ChatGPT is a variant of the GPT (Generative Pre-trained Transformer) model developed by OpenAI. It is designed specifically for natural language understanding and generation in a conversational context. ChatGPT is trained on a large dataset of text from the internet and can generate human-like responses to text prompts. It is capable of answering questions, engaging in conversations, generating text, and more, making it useful for a wide range of natural language processing tasks.

OpenAI has released different versions of GPT models, and ChatGPT represents one of those iterations. It’s a powerful tool for chatbots, virtual assistants, content generation, and various other applications where natural language processing and generation are required. Developers and organizations can use ChatGPT to build applications that interact with users through text-based conversations.

You can use ChatGPT for personal reasons or for professional tasks.

How is ChatGPT different from Microsoft 365 Copilot?

ChatGPT and Microsoft Copilot are both AI-powered language models, but they serve different purposes and contexts. ChatGPT is designed for natural language understanding and generation, making it versatile for various applications like chatbots and content generation.

In contrast, Microsoft 365 Copilot is a coding assistant specifically tailored for Microsoft 365 users, assisting them with collaboration, content creation, autocompletion, and documentation within Office 365 apps. While ChatGPT is focused on general natural language tasks and is accessible through APIs, Copilot is integrated directly into Microsoft 365 and is trained on task connected with Office 365 apps.

ChatGPT is trained based on the publicly available data on the Internet. It’s trained on a broad range of sources, including websites, books, articles, and other publicly available text on the web. This training data covers a wide array of topics and languages.

On the other hand, Microsoft 365 Copilot uses LLM, and the data gathered in your Microsoft 365 environment. Copilot will use your emails, documents, or company data structure to deliver tailored responses to your needs.

How security of your data look like in ChatGPT vs. Microsoft Copilot?

Security and privacy of your data are some of the biggest concerns in the area of using Generative-AI, like ChatGPT or Microsoft 365 Copilot.

When you are using OpenAI ChatGPT you need to remember that this publicly available service uses the data shared by you based on its Terms of Use and Privacy Policy. OpenAI can gather information about you and your use of ChatGPT to evolve their product.

In such a case using organization data in ChatGPT could be quite risky. At some point, you can lose control of what happening with your data.

On the other hand tools like Bing Chat Enterprise and Microsoft 365 Copilot are focused on delivering Commercial Data Protection to allow you to use your organization’s data in a safe way.
