Large AI models can lie to their users under pressure, according to a study called Model Alignment between Statements and Knowledge (MASK). While various tests and tools test AI for accuracy, the MASK benchmark was designed to determine whether an AI believes what it tells users — and under what circumstances it might provide incorrect information. The study tested 27 models from the GPT, Llama, Qwen, Claude, and DeepSeek families.

Two childhood friends, developer Roman Galdava and graphic designer Vadym Yaremchuk, created a tool to increase video views on YouTube — Thumbnailed it. It analyzes audience preferences and creates optimized cover, title, and description with a focus on clickability. Thanks to this, the user quickly receives a ready-made design for a YouTube video by simply sending a link to the script to the bot. The startup is already on its way to its first investment, and in the future it plans to expand the list of niches, including Amazon.

My name is Diana, I am a software developer at the product company BOTMAKERS LLC. For some time, I have been actively working on Instafill.ai technology, the main task of which is to relieve lawyers and ordinary users from the routine of filling out PDF forms. In this article, I want to reveal what solution became the foundation for our project and show how we improved it in practice. My task is not just to tell about my own experience, but also to show the evolution of the Instafill.ai idea: from the initial concept in the form of a simple Python script to a modern tool. This material will be useful for developers who want to optimize work with documentation and create intelligent systems for automation. Who knows — maybe our experience in developing Instafill.ai will become a starting point for your experiments!

A 32-year-old Ukrainian developer from Uzhhorod, before the full-scale invasion, had been working peacefully for more than 10 years in many companies, creating various software for his customers, and had never thought about a different fate. However, since February 2022, a full-scale invasion has turned his life and work upside down, as it has for many Ukrainians. The man joined the hacker community, but chose the «white» side of the force. The hunter under the nickname «stopwar» told dev.ua about what attracted him to this field, what distinguishes «black» hackers from «white» or «ethical» hackers, and what a specialist can expect in the future.

Hello! It’s #vsrativakansii again. And again, there are a few crony offers and HR stories that are being hotly discussed by IT people.

A few years ago, the profession of a producer was associated with show business, celebrities, and big money. Today, this is a person who explains to a senior with 10 years of experience that recording a video about bugs is more important than the bugs themselves. And rehearsing a webinar is more serious than a code review. If this seems like a simple task to you, try persuading an IT guy to re-record a lesson because of one mispronounced word. IT education has already turned into a separate industry, in which the producer plays one of the key roles. Darya Bilokon, Producer Team Lead of the Laba and robot_dreams online schools, told dev.ua about the profession and its features in the section on IT professions.

OpenAI has trained its GPT-4o model to generate images and has made it available to paid subscribers. The model has been shown to be adept at imitating the distinctive style of famous cartoons and anime, which has led social media users to take a liking to the way it converts famous images (including the White House brawl) into different settings. Here’s what intellectual property experts have to say about it.

Justin C. Pearson, founder and CEO of recruiting service Mission Box Solutions, compared a virtual interview to a first date. That’s why he advises dressing to make an impression. What do IT professionals think about this and how do they dress for an online interview?

The recent delisting of the JELLY token from the Hyperliquid platform has sparked widespread discussion about the risks in decentralized finance (DeFi), as well as raised questions about market trust and transparency. Together with an expert from Bitget Research, we took a detailed look at why this incident occurred and how it will affect the market.

My name is Vlad Chukhrai, and before becoming a project manager at the fintech company bill_line, I held a position in business support. In the case of payment service providers, support does not solve problems with payments of specific customers — this is done by the merchant we work with. The support team that handles processing looks at a more strategic level: how to solve a specific merchant problem in the context of the full transaction processing cycle and how to avoid illegal actions with people’s money. Today I would like to talk about my own experience based on cases and rules that the company has.

22-year-old Bohdan Oliynyk has been working as a DevOps Engineer for 8 months, has already worked on more than one project and has brought many solutions, having a Strong Junior level closer to Middle. However, he recalls that he never thought that he would choose this specialty, and he managed to get into IT only on the fourth attempt. Twice he started learning Front-end, twice — Python, at some point he even had the thought that this field was not for him. But the young man did not give up his attempts and in the end they were crowned with success. He told dev.ua about all the ups and downs and shared life hacks that can help other beginners find themselves in the technosphere.

A powerful historical update of ChatGPT has taken place. Now the chatbot can be used to generate images and process existing visuals and photos. Previously, I always said that ChatGPT or Gemini are, to put it mildly, not the best AI services for generating images and working with this content format. This is not their main profile. But the situation is changing.

On March 25, the taxman exposed two chains of appliances and electronics stores in evading taxes by UAH 286 million. According to «Ekonomichna Pravda», these are the chains «Yabko» and «Yabluka», in which massive facts of sales without the use of RRO/PRRO, as well as the lack of accounting for goods and documents on the origin of equipment were revealed. It is known that legal entities involved up to 300 related individual entrepreneurs on a simplified system. dev.ua found out who owns the stores and what is happening in the gadget market.

OpenAI CEO Sam Altman has unveiled a major update to ChatGPT’s image generation capabilities. Now, the AI ​​chatbot can use OpenAI’s GPT-4o model to create and modify images and photos. What are the advantages and disadvantages of image generation in GPT-4o?

Many professionals have already realized that IT is not only about code, startups and remote work from anywhere in the world. It is also about money. Big money. And if you work in the industry, why not find out where there is the most of it? This question made me dive into numbers, trends and analytics — and now I share with you the most interesting ones.

Cybercriminals are actively implementing artificial intelligence to scale attacks and generate profit. Malware generation, automated phishing, and self-learning AI worms are just some of the tools used in modern cybercrime. dev.ua tells how malicious AI models are changing the cyberthreat landscape.

The trend of vibe coding, where programmers simply ask AI to perform certain tasks and do not delve into the actual code offered by the chatbot, is gaining momentum, and IT professionals have different (sometimes negative) opinions about this practice. However, a number of representatives of prominent tech companies believe that vibe coding can increase programmer efficiency. Here’s what they advise.

A major leak of information related to the Donald Trump administration has occurred in the US. An American journalist accidentally found himself in a Signal chat room where top officials were discussing an attack on military targets in Yemen. Why are such stories happening more and more often? And how does high-level communication take place in Ukraine?

Google and the Computer History Museum (CHM) have released the source code for AlexNet, a convolutional neural network (CNN) that many credit with transforming the AI ​​field in 2012. The Python code, now available on CHM’s GitHub page as open source software, offers AI enthusiasts and researchers a glimpse into one of the pivotal moments in IT history. We tell the story of the legendary neural network, which was trained on a computer in the bedroom of one of its creators' parents. It was created by Ukrainian Alex Kryzhevsky, OpenAI co-founder Ilya Sutzkever, and computer scientist Jeffrey Hinton.

News streams are so large that information needs to be presented as quickly as possible. Some events crowd out others, so there is no time for several hours of video editing. In this case, artificial intelligence comes to the rescue. And many media outlets are already using its capabilities.

This is a new episode of our show, Sho on AI, in which we analyze the latest news in the field of artificial intelligence, as well as learn a little about how to work with new AI tools, joke around and invite interesting guests. We often show scary things. In this episode, we show how the Chinese AI agent Manus simultaneously manages several dozen X-accounts and more.

Ukrzaliznytsia is under a large-scale cyberattack — online ticket sales have been down for the second day, the SBU has been involved. At this time, the railway continues to operate despite physical attacks on the infrastructure, and insidious cyberattacks cannot stop it. The good news is that the system will be restored from backups. But the company is in no hurry with this. Why is that? De Novo specialists comment.

Game UX/UI Designer Oleksandr Matkovsky asked in his LinkedIn post why a candidate would volunteer to do an unpaid test assignment for a company with which he had not even discussed working conditions. He provoked a lively discussion, to which Ksenia Larina, a marketer and CEO of Larination School, responded, explaining why she has only offered paid test assignments for 6 years.
