Introduction: The Artificial Intelligence Revolution in Business

Artificial intelligence (AI) is no longer just a futuristic concept in sci-fi movies. It’s here, and it’s real. From self-driving cars to chatGPT code interpreters that provide automated customer service solutions, AI is changing the way business is done. But what makes it so revolutionary? And how can companies take advantage of the flood of data these technologies generate?

Why data analytics is more than just numbers

Data is the new gold, they say. But data alone is like a diamond in the rough. It takes the right technology and expertise to discover its true value. It’s not just about numbers and statistics. It’s about pattern recognition, predictive analytics and data-driven decision making

A few examples that illustrate the point

  • Analyzing customer behavior for personalized marketing strategies.
  • Optimizing supply chains through real-time tracking and predictive models.
  • Risk assessment in the financial industry through complex algorithms.

So data analytics is not just a numbers game, but a powerful tool for strategic planning and operational excellence

AI technologies that change the game

The AI market is like a lavish buffet with a wide range of technologies. We have chatbots that answer customer queries and voice assistants that turn your home into a smart home. But that’s just the tip of the iceberg

Table: Revolutionary AI technologies

Technology Application Example
NLP (Natural Language Processing) Chatbots, translation software WonderChat chatbot
Computer vision Facial recognition, automated inspection Overview Text & Image AI
Machine learning Predictive models, algorithm trading Finetuning OpenAI GPT

We’re just scratching the surface here. AI technologies are versatile and can provide a real competitive advantage.”

As you can see, that’s already a pretty good output. Now, we haven’t defined any text length or parameters, such as temperature. This should be just a short presentation of the possibilities of the Custom Instructions, how you can control the output well and directly also create internal links in the output

A small tip from us: If you use the Custom Instructions, please always remember that you have to redefine them partially for new chats. For example, if you want to create texts for your private purposes once and then work for your or a company in the next chat, don’t forget to adjust the Custom Instructions. The default setting is that they should apply to new chats as well. You can disable this in the small slider below the 2nd field here
