The artificial intelligence industry is never standing still, and the last 24 hours have been particularly eventful. OpenAI has launched its new model, Amazon has revamped its voice assistant, and a philosophical divide in the market is beginning to shape the future of AI. How should entrepreneurs and innovators navigate this landscape? Let’s take a look at the key developments.

ChatGPT 4.5: OpenAI's new bet for more natural conversations

OpenAI has released ChatGPT 4.5, its new artificial intelligence model for natural language processing. The big difference promised is the ability to maintain “emotionally subtle conversations” and a more natural interaction with users.

According to Earth, ChatGPT 4.5 is considered the most capable model yet, with significant improvements in writing and knowledge skills. The company also claims that it “leaks less” than previous versions, solving one of the biggest problems with this type of technology.

An interesting detail revealed by S.Paulo Newspaper is that OpenAI used training techniques inspired by DeepSeek, a Chinese company that has been gaining prominence in the sector. This move shows how global competition is intensifying technological development, where even market leaders need to observe and incorporate innovations from emerging competitors.

In my experience with startup acceleration, I see that this “observe, adapt, and improve” approach is essential to remain competitive in fast-moving markets. The next major launch expected is GPT-5, scheduled for May, which promises to bring even more significant innovations.

Alexa+: Amazon revamps its assistant with generative AI

Amazon has launched Alexa+, an overhaul of its voice assistant that now incorporates generative artificial intelligence. This isn’t just an incremental update, but a complete reimagining of the virtual assistant.

According to the CNN Brazil, the new version promises more personalized service, storing user preferences and adapting to interactions. Alexa+ will be free for Prime members, showing Amazon's strategy of using AI as a competitive differentiator in its service ecosystem.

This move is extremely strategic. Voice assistants have struggled to find their place as truly indispensable tools. By incorporating generative AI, Amazon can finally transform Alexa from a simple device for basic commands into a genuinely useful contextual assistant.

In my work with corporations, I’ve seen how generative AI is becoming the most important competitive differentiator for digital products and services. Companies that can integrate these capabilities in intuitive and useful ways will be the winners in the next phase of the digital revolution.

The AI War: Cavaliers vs. Roundheads

An interesting philosophical divide is emerging in the AI market, as reported by Brazilian Post Office. The current panorama is separating between two approaches:

• Cavaliers: Focused on the pursuit of artificial general intelligence (AGI), with a more visionary and ambitious approach.
• Roundheads: Focused on solving specific problems with pragmatic and well-defined solutions.

This tension has the potential to significantly impact investments in the sector, leading investors to make crucial choices between these divergent views. The shares of companies such as Nvidia and Google are already reflecting this divide.

As someone who has been following the innovation ecosystem for over two decades, I see that this polarization is not uncommon in times of technological acceleration. In the early days of the internet, we also experienced similar divisions between visionaries and pragmatists.

For Brazilian entrepreneurs, my recommendation is to keep the focus on real problems and practical solutions (Roundhead approach), but without losing sight of the horizon of possibilities that generative AI brings. In the context of emerging markets like ours, solutions that solve specific pain points are more likely to be successful immediately.

AI in healthcare: technology at the service of humanized care

One of the fields where AI is generating the most significant impacts is healthcare. According to the LOOK, artificial intelligence is transforming healthcare, offering tools to reduce bureaucracy and improve interactions between doctors and patients.

Automatic transcription of consultations and analysis of exams by AI allows doctors to focus more time on what really matters: humanized care and accurate diagnoses. The healthcare sector expects significant growth in investments in AI, increasing the efficiency and quality of care.

This is a perfect example of what I have always advocated: technology should serve to make us more human, not less. AI does not replace the doctor, but it frees up their time so they can better exercise their humanity and expertise.

Brazilian startups have a fertile field to explore at this intersection between AI and healthcare. In my mentoring work, I have seen promising initiatives that use AI to democratize access to quality healthcare, a critical problem in our country.

Amazon eliminates candidates who use AI in interviews

A curious case was reported by Economic Value: Amazon is disqualifying candidates who use artificial intelligence in job interviews, considering it an “unfair advantage”.

The company has implemented new guidelines to identify behaviors associated with the use of AI during hiring processes. This raises important questions about ethics, authenticity and the limits of using assistive technology in professional contexts.

This situation illustrates a dilemma we will increasingly face: how to balance the use of AI tools as productivity enhancers versus their use as substitutes for human critical thinking and creativity.

For professionals who are in the job market or seeking new opportunities, my recommendation is clear: use AI as a preparation and learning tool, but in decisive interactions, let your authenticity and original thinking prevail. AI should amplify your capabilities, not replace them.

Tax return with the help of ChatGPT? The limits of AI in specialized tasks

As the Income Tax declaration period approaches, the Accounting Portal analyzed whether tools like ChatGPT can help taxpayers in this task.

The bottom line is that AI has the potential to help interpret tax rules and identify deductions, providing greater efficiency. However, there are significant limitations, especially when interpreting complex tax scenarios, in addition to concerns about the security of sensitive data.

The role of the accountant remains crucial in more complicated tax situations, demonstrating that AI works best as an assistant and not as a replacement for specialized professionals.

This is an important reminder that we are only at the beginning of the AI revolution. There are still many tasks where human judgment, contextual knowledge, and professional responsibility are irreplaceable.

AI in Justice: a delicate balance between innovation and justification

The use of artificial intelligence in the Brazilian Judiciary continues to advance, but not without challenges. Conjur reports that the recent update of CNJ Resolution 332/2020 seeks to ensure that the use of AI preserves fundamental rights, requiring human supervision in decisions.

This is a particularly sensitive area, where transparency and the ability to substantiate are absolutely necessary requirements. Regulation faces the challenge of balancing innovation with legal certainty, ensuring that trust in the justice system is not compromised.

It is fascinating to see how different sectors are approaching the incorporation of AI. The judiciary, naturally conservative by its very nature and function, needs to move at a different pace than sectors such as technology or marketing, for example.

Gen Z trusts AI more than humans at work

A revealing study was reported by Forbes Brazil: Generation Z (born between 1997 and 2012) trusts artificial intelligence more than humans to solve problems at work. About 411% of young people in this generation show a preference for AI as a source of solutions.

This trend raises important concerns about interpersonal communication and trust in the workplace. The study emphasizes that companies should help young people use AI in a balanced way, warning against the risks of blindly trusting the technology.

As an educator and professional who works with talent development for the technology market, I have been watching this phenomenon closely. On the one hand, it demonstrates this generation’s natural ease with digital tools; on the other, it signals a possible deficit in human collaboration skills.

At Sirius, one of the neo-universities I founded, we have always emphasized that technical skills need to be developed in parallel with socio-emotional skills. In an increasingly automated world, the true human competitive advantage will lie precisely in the capabilities that machines cannot replicate.

What can we expect?

The news of the past 24 hours clearly shows that we are in a moment of acceleration in AI development. The launch of ChatGPT 4.5, the redesign of Alexa, and the emergence of models like DeepSeek R1 indicate that competition is intensifying innovation.

As entrepreneurs and leaders, we need to be aware of three main dimensions:

• Technological: Monitor advances and understand how they can be applied to our business;
• Human: Reflect on how these technologies affect behaviors, trust and work relationships;
• Regulatory: Look at how different industries are setting boundaries and guidelines for the responsible use of AI.

In my mentoring work with startups, I have emphasized the importance of a balanced approach: making the most of AI’s capabilities while still maintaining the centrality of the human experience and business ethics. Companies that strike this balance will be best positioned to thrive in this new landscape.

Whether you are developing a startup that uses AI or want to incorporate these technologies into your existing business, remember that the difference lies not only in the technology itself, but in how it solves real problems and generates value for people. In my mentoring, I help entrepreneurs find this balance and navigate this complex but opportunity-filled scenario.

The AI revolution is just beginning, and today’s news is just a glimpse of what’s to come. We are living in a historic moment, and it’s up to us to shape it to create a more prosperous, inclusive, and humane future.
