M365 Copilot vs. Corporate LLM: What is Sufficient for SMEs? | Blog

1. The Initial Situation

With the increasing adoption of AI technologies, many SMEs face the decision of which solution best fits their existing infrastructure and strategic goals. This brings us to the central question: Should companies rely on the extensive and immediately usable capabilities of Microsoft 365 Copilot, or is it more sensible to invest in developing their own corporate LLM?

2. The Strategic Solution Approach

Microsoft 365 Copilot is particularly attractive when it comes to quickly integrating AI into existing Microsoft ecosystems. The main advantages lie in implementation speed and lower entry costs. In contrast, custom corporate LLMs offer more adaptability, which is especially beneficial for companies with specific requirements or data protection concerns.

3. Practical Example: Mechanical Engineering Company

Let’s assume a medium-sized mechanical engineering company with around 200 employees is faced with the decision to integrate one of the mentioned AI solutions. With its existing IT infrastructure, which is heavily integrated into the Microsoft ecosystem, Microsoft 365 Copilot could be a faster and more cost-effective solution. However, since this company has specific requirements regarding product data security, developing its own LLM could be considered to allow for more targeted control.

4. Business Value and ROI

The choice between Microsoft 365 Copilot and a corporate LLM must be viewed in terms of business values. The Copilot can bring significant time savings by automating routine tasks, while a custom LLM offers long-term competitive advantages through tailored AI features.

5. The First Three Steps to Implementation

• Analysis of Corporate Requirements: Identify the specific pain points and potentials in your business processes.
• Evaluation of Solution Options: Compare the functionalities of Microsoft 365 Copilot and a customized LLM regarding your business goals.
• Prototyping and Testing Phase: Implement a pilot project to test the chosen solution on a small scale for informed decision-making.
