Over the last few days, a small AI experiment has been circulating across LinkedIn and Reddit: open a completely fresh ChatGPT session, ask for a random number between 1 and 100, and observe what happens. Surprisingly often, the answer is 73. Sometimes it is 42. In English sessions, 79 also appears more often than true […]

AI-driven stock picking agents are often presented as the next step in quantitative investing. The narrative is compelling: autonomous systems ingest market data, reason over it, and continuously improve decisions through feedback loops. In theory, this aligns well with modern machine learning paradigms and agent-based architectures. In practice, the situation is more constrained. These systems

If you believe hallucinations in AI will disappear with the next model release, this blog post might be uncomfortable to read. Because they won’t. And this is not because the technology is broken or because engineers haven’t tried hard enough. It’s because this is not a product problem in the first place. And for everyone

Over the past year, the discussion in AI has gradually shifted away from models as isolated reasoning engines and toward agents as autonomous operational systems. Large language models are no longer framed merely as tools for generating text or answering questions. They are presented as components capable of planning, acting, coordinating across APIs, and making

This project did not start as an attempt to build a generic image recognition system or to benchmark computer vision frameworks. It started with three teddy bears that have been traveling with me since 2017. Over the years, they have accompanied me on flights, through airports, into hotel rooms, conference venues, cafés, and occasionally onto

This „project“ did not start with the ambition to build a generic document classifier or to compete with existing document management systems. It started with a much more personal and probably familiar situation. I wanted to explore whether machine learning could help me to organize my PDFs better. Not reminding me of deadlines or summarizing

Why equating generative models with intelligence is technically wrong — and dangerous. At some point in the last two years, the term Artificial Intelligence stopped meaning what engineers and scientists meant by it.It became shorthand for anything that calls an OpenAI API or produces text that sounds clever. But a system that completes your sentences

You’ve heard the buzz. AI is changing everything. Machine learning is everywhere. And yet, behind all the jargon and hype, the basic mechanics of how it works often get lost in translation. So let’s fix that.Here’s a no-fluff, clear-eyed walkthrough of how machine learning actually works—broken into five essential steps. No advanced math. No mysterious

The world of investing has always been a numbers game, but in the age of AI, those numbers are being processed at an unprecedented scale and speed. Financial markets generate vast amounts of data every second—price movements, trading volumes, earnings reports, economic indicators, and news sentiment. AI is transforming how investors analyze this information, identify

The phrase “data is the new oil” has become a common metaphor in the digital economy, emphasizing data’s immense value as a driver of business and technological innovation. However, like crude oil, raw data in its unprocessed form is not inherently useful. Just as oil must undergo refining before it can power industries, data must
