OpenAI unveils the O3-Pro model

2025 June 12. 09:58   

OpenAI has launched its O3-Pro model, which replaces O1-Pro and promises significant performance advances in science, education, programming, data analysis and scripting.

The O3-Pro model is designed to provide ChatGPT with more reliable answers with longer think time. Performance tests show that O3-Pro excels in math, science and coding, outperforming both O3 and O1-Pro models. Although O3-Pro response times may be slightly longer than O1-Pro, OpenAI believes that the extra latency is justified, especially for complex and challenging tasks.

OpenAI stresses that O3-Pro makes ChatGPT a more versatile tool. It will be able to search web pages, analyse documents, interpret visual content, use Python, and provide personalised responses through the in-memory feature. It should be noted that for technical reasons, O3-Pro does not currently support Canvas and image generation. For this, users will need to use other models such as the GPT-4o, O3 or O4-Mini. Pricing for the O3-Pro API is $20 per million input tokens and $80 per million output tokens.

The O3-Pro model will be available to ChatGPT Pro/Team subscribers from 11 June and will also be available to developers via the API. Enterprise and Edu subscribers will get access next week.

In addition, OpenAI has updated ChatGPT's enhanced voice mode, which allows for more natural and smoother conversations for subscribers. ChatGPT's voice feature now also offers intuitive and efficient language translation: simply instruct ChatGPT to translate and it will translate continuously throughout the conversation until you ask it to stop or change language.

After a Historic Turn, SK Hynix Becomes the New Market Leader in the Memory Industry

 For three decades, the name Samsung was almost synonymous with leadership in the DRAM market. Now, however, the tables have turned: in the first half of 2025, South Korea’s SK Hynix surpassed its rival in the global memory industry for the first time, ending a streak of more than thirty years. This change signifies not just a shift in corporate rankings but also points to a deeper transformation across the entire semiconductor industry.

The Number of Organized Scientific Fraud Cases is Growing at an Alarming Rate

 The world of science is built on curiosity, collaboration, and collective progress—at least in principle. In reality, however, it has always been marked by competition, inequality, and the potential for error. The scientific community has long feared that these pressures could divert some researchers from the fundamental mission of science: creating credible knowledge. For a long time, fraud appeared to be mainly the work of lone perpetrators. In recent years, however, a troubling trend has emerged: growing evidence suggests that fraud is no longer a series of isolated missteps but an organized, industrial-scale activity, according to a recent study.

Beyond the Hype: What Does GPT-5 Really Offer?

 The development of artificial intelligence has accelerated rapidly in recent years, reaching a point where news about increasingly advanced models is emerging at an almost overwhelming pace. In this noisy environment, it’s difficult for any new development to stand out, as it must be more and more impressive to cross the threshold of user interest. OpenAI carries a double burden in this regard: not only must it continue to innovate, but it also needs to maintain its lead over fast-advancing competitors. It is into this tense landscape that OpenAI’s newly unveiled GPT-5 model family has arrived—eagerly anticipated by critics who, based on early announcements, expect nothing less than a new milestone in AI development. The big question, then, is whether it lives up to these expectations. In this article, we will examine how GPT-5 fits into the trajectory of AI model evolution, what new features it introduces, and how it impacts the current technological ecosystem.

The Most Popular Theories About the Impact of AI on the Workplace

 Since the release of ChatGPT at the end of 2022, the field of AI has seen impressive developments almost every month, sparking widespread speculation about how it will change our lives. One of the central questions concerns its impact on the workplace. As fears surrounding this issue persist, I believe it's worth revisiting the topic from time to time. Although the development of AI is dramatic, over time we may gain a clearer understanding of such questions, as empirical evidence continues to accumulate and more theories emerge attempting to answer them. In this article, I’ve tried to compile the most relevant theories—without claiming to be exhaustive—as the literature on this topic is expanding by the day. The question remains: can we already see the light at the end of the tunnel, or are we still heading into an unfamiliar world we know too little about?
