, agents perform actions. That’s exactly what we’re going to try out in today’s article. In this article, we’ll use LangChain and Python to build our own CSV sanity check agent. With this agent, we’ll automate typical exploratory data analysis (EDA) tasks as displaying columns, detecting missing values (NaNs) and retrieving descriptive statistics. Agents decide step by step which tool …

Carl Gauss was a German mathematician and astronomer, also known as the “Prince of Mathematics”. He is widely recognized for his contributions in the fields of science and mathematics, such as number theory, geometry, algebra, astronomy, magnetism, etc. Even today, a number of mathematical and scientific concepts are named after him. One such concept is the Gaussian Addition, which we …

arXiv:2509.05197v1 Announce Type: cross Abstract: Automated web testing plays a critical role in ensuring high-quality user experiences and delivering business value. Traditional approaches primarily focus on code coverage and load testing, but often fall short of capturing complex user behaviors, leaving many usability issues undetected. The emergence of large language models (LLM) and AI agents opens new possibilities for web …

How can startups and developers actually monetize their AI products? A startup called Koah, which recently raised $5 million in seed funding, is betting that ads will be a big part of the answer. If you spend any time online, there’s a good chance you’ve seen plenty of ugly, AI-generated ads — but few to none when interacting with AI …

Mistral AI, the French company behind AI assistant Le Chat and several foundational models, is officially regarded as one of France’s most promising tech startups and is arguably the only European company that could compete with OpenAI. It is reportedly in the process of raising another round that would value it at $14 billion, up from about $6 billion in …

exploring features in the OpenAI Agents SDK framework, there’s one capability that deserves a closer look: input and output guardrails. In previous articles, we built our first agent with an API-calling tool and then expanded into a multi-agent system. In real-world scenarios, though, building these systems is complex—and without the right safeguards, things can quickly go off track. That’s where …

On Friday, a startup called Fable announced an ambitious, if head-scratching, plan to recreate the lost 43 minutes of Orson Welles’ classic film “The Magnificent Ambersons.”  Why is a startup that bills itself as the “Netflix of AI,” and that recently raised money from Amazon’s Alexa Fund, talking about remaking a movie that was first released in 1942?  Well, the …

OpenAI is reorganizing its Model Behavior team, a small but influential group of researchers who shape how the company’s AI models interact with people, TechCrunch has learned. In an August memo to staff seen by TechCrunch, OpenAI’s chief research officer Mark Chen said the Model Behavior team — which consists of roughly 14 researchers — would be joining the Post …
