While this "persona prompting" is great for nailing a specific tone of voice, recent empirical research reveals a surprising truth: when it comes to logical reasoning, coding, and factual accuracy, role-playing actually degrades AI performance.

The key to sustainable AI success, on the other hand, lies in a simple principle: start small and then, based on your own individual service processes, look at which use cases AI can actually be a relief.

Choosing the right model can be crucial, especially for more complex tasks. Different large language models have different strengths - and sometimes a change of model is the quickest way to achieve the goal.

Large language models (LLMs) are currently outdoing each other not only through better performance, but also through ever larger so-called context windows. But what does that actually mean?

Technological developments are happening one after the other, and this also applies to the further development of LLMs. What used to be text-based language models are now omni-modal.

AI is more than just a tool for quickly answering questions – it can uncover in-depth patterns and thought processes. This requires the right prompts.

Germany is in the midst of an economic crisis. And if you not only want to survive it, but end it, the issue of efficiency gains is key. AI-based solutions and AI technology can bring significant benefits here.

To really meet customer needs, companies need to listen to their customers better. This requires analyses and predictions of customer behavior. But here, as the CEX Trend Radar 2025 shows, too little is happening.

How can chatbots and voicebots be used to access current and internal knowledge? This is where RAG comes into play.

Comprehensive testing is crucial for companies to be able to use large language models (LLMs) safely and effectively. This is because models that are not thoroughly tested can deliver incorrect or biased results.

One urgent security issue at the moment is the implementation of the EU AI Act - and therefore the protection of personal data through anonymization and pseudonymization. Tip: There is technical support for this.

Cyber threats are becoming increasingly sophisticated. This means that our defenses must become smarter as well.

With AI, it's easy to get carried away by technological breakthroughs and the potential. But we must not lose sight of one critical aspect: ethics.

There is hardly a sector of the economy that is not yet looking at the opportunities offered by AI. But instead of jumping on the bandwagon, many companies are afraid of - well, what actually?

AI is permeating companies and our work. We are confronted with new announcements almost every day. One of the main drivers for the implementation of AI is the pursuit of greater efficiency. A major obstacle is uncertainty.

The EU AI Act provides for the categorization of AI systems into risk groups. Many systems in customer service will probably be categorized as "minimal risk" or "limited risk".

Previously, the legal requirements for the use of AI in customer service were primarily shaped by laws and regulations governing the processing of customers' personal data. With the EU AI Act, additional regulations have been introduced.

The extremely powerful AI chatbot ChatGPT is the talk of the world – but what are the benefits of using it specifically in customer service?

I'm holding the first results of the Contact Center Trend Study in my hand and I can see: The potential of AI is not yet fully exploited!

Automation can be customer-friendly and service-oriented. And it can support employees instead of replacing them.

In the competition for qualified talent, contact centers often miss out. So it's high time to focus on the employee experience.

Language shapes communication and interaction. If you understand its effect, you can use it in a targeted and effective way.

Although AI and psychology are closely related, the two branches of science have mostly gone their separate ways. However, the two research approaches can now be combined. This leads to interesting findings and possibilities.

Where people still like to make a lot of phone calls, AI is able to provide effective support to make calls more successfully.

We all know the cost pressure in call, contact and service centers. Unfortunately, they are still far too often run as cost centers.
