From Scientific Contribution to Digital Fraud: What Are the Real Faces of Modern AI Models?

June 20, 2026 jarvis

    Welcome to the era where artificial intelligence is no longer just an experiment in laboratories, but a tool used by millions of people every day. While scientists like Maty Boháček from Stanford point to the incredible usefulness of large language models (LLMs), tech giants like Google face a new challenge: the abuse of these capabilities for massive fraud. Are we standing on the threshold of a new era of productivity, or are we just learning to control the most powerful tool for disinformation?

The world of large language models (LLMs) is going through a period of extreme growth and, at the same time, deep polarization. On one side, we have developers whose models are becoming an integral part of the digital lives of millions of users, and on the other side, we see growing risks related to cybersecurity and the misuse of AI to manipulate people.

Usefulness vs. intelligence: What do LLMs actually do?

Maty Boháček, who works in the research environment of Stanford University, presents a perspective that is crucial for the average user: AI is not just a toy, but a tool with real benefits. His models, just like those from OpenAI or Google, can speed up work, help with programming, or serve as a creative partner.

Here, however, we encounter a fundamental scientific dispute. As Radio Wave states, experts like Gary Marcus warn that these models are not truly intelligent in the human sense of the word. They distinguish between pattern matching and genuine understanding of reality. LLMs are masters at predicting the next probable word, but they cannot guarantee that their answer corresponds to physical reality.

For the Czech user, this means one crucial thing: AI is a great assistant, but a poor authority. If you use models like ChatGPT or Gemini for creating texts in Czech, the results are excellent, but you must always verify the facts. Czech localization among the biggest players is currently at a very high level.

Comparison of top models (as of June 2026)

To understand where we stand, we need to look at the current top of the market. Most of these tools offer a free tier (at no cost) and a paid version around 20 USD / month (approx. 470 CZK), which is standard for both individuals and businesses.

GPT-4o/GPT-5 (OpenAI): Still the leader in logical reasoning and complex programming. Great Czech language support.
Gemini 2.0 (Google): The strongest integration with the Google Workspace ecosystem. Extremely fast processing of long contexts (e.g., entire books or hours of video).
Claude 3.5/4 (Anthropic): Often preferred for its "more human" and less robotic writing style, appreciated by authors and copywriters alike.

The dark side: AI as a tool for fraud

While Maty Boháček talks about usefulness, the reality on the market also shows very dangerous aspects. Recent reports of legal disputes between Google and other parties (e.g., in connection with Samsung) point to a phenomenon where the capabilities of AI models like Gemini are abused to create highly convincing scams. Samsung Magazine reported on million-dollar frauds where attackers use AI to generate personalized phishing attacks or fake identities.

For the average person, this means that digital trustworthiness is becoming a rare commodity. It is no longer enough to trust an email from a "bank" or a voice message from an "acquaintance," because AI can imitate any communication style and voice tone with incredible accuracy.

Impact on the Czech market and EU regulation

For Czech businesses and individuals, a key factor is the EU AI Act. Unlike the USA or China, where the approach to AI development is much more open, the European Union is introducing strict rules for high-risk systems. This has two impacts:

Higher security: Companies in the Czech Republic will have to demonstrate that their AI tools are transparent and safe.
Implementation complexity: For small Czech businesses, complying with regulations can be administratively demanding, but at the same time, it provides a competitive advantage in the form of customer trust.

If you are looking for tools for your company in the Czech Republic, we recommend focusing on models that guarantee data protection within the EU (e.g., Microsoft Azure AI or local implementations via API with European servers). The price for business versions usually starts from 25 USD/month, but includes a critical security layer.

Conclusion: How to survive in this world?

Artificial intelligence is neither a miracle nor the end of the world. It is an extremely powerful statistical tool. The key to success is the combination of AI speed and human critical thinking. Use models for efficiency, but never trust them without verification, especially on matters of security and factual data.

Is my data safe when I use ChatGPT or Gemini in Czech?

Standard free versions often use your conversations to train models. If you work with sensitive company data, you need to use paid business versions (Enterprise/Team), which guarantee that your data will not be used for further training.

How do I know if I'm communicating with AI and not a human?

Look for signs of "hallucinations" (making up facts), overly repetitive sentence structure, or unusually fast response times. In case of suspicious financial requests, always switch to another communication channel (e.g., a phone call).

Can AI truly replace human intelligence?

According to current scientific knowledge, no. AI excels at data analysis and generating content based on patterns, but lacks true consciousness, emotions, and the ability to understand the deep context of the world beyond textual/visual data.
