GPT-5 delayed
OpenAI's development of GPT-5 has encountered delays due to technical challenges and infrastructure constraints. Initially, OpenAI planned to integrate various models into GPT-5 for a unified AI system. However, CEO Sam Altman acknowledged the complexity of this integration and the need for substantial capacity to meet anticipated demand.
Consequently, OpenAI has decided to first release the o3 and o4-mini models in the coming weeks, with GPT-5's launch now expected in a few months. Additionally, GPU shortages and unprecedented demand have further impacted the release schedule, leading to temporary service limitations and delays in new product launches. Despite these setbacks, OpenAI remains committed to delivering GPT-5, aiming for significant advancements in AI capabilities upon its eventual release.

NotebookLM adds "Discover Sources" feature
Google’s NotebookLM, designed to help users understand and explore topics more deeply, has launched a major new feature called Discover Sources, aimed at simplifying the research process. Previously, users had to manually upload documents, like research papers, interviews, or travel plans. Now, with a simple tap of the new Discover button, users can describe any topic of interest, and NotebookLM — powered by Google's Gemini AI — will quickly scan the web to present up to 10 curated sources, each with annotated summaries explaining their relevance.
These sources can be added to a notebook instantly and used alongside other NotebookLM tools such as Briefing Docs, FAQs, Audio Overviews, and citation or note-taking features. A playful “I’m Feeling Curious” option even suggests random topics to explore. This rollout marks the beginning of a broader effort to make NotebookLM smarter and more proactive, using AI to streamline how users gather and organize information. The feature began rolling out this week and will be available to all users within days.

Microsoft Copilot = AI companion
On its 50th anniversary, Microsoft unveiled significant enhancements to its AI assistant, Copilot, introducing features such as the ability to perform actions on most websites (e.g., booking tickets and making reservations), personalized memory to recall user preferences, real-time video analysis via smartphone cameras, and new tools like 'Pages' and 'Deep Research' for organizing information and conducting comprehensive research. These updates aim to provide a more personalized and proactive user experience, positioning Copilot competitively alongside AI counterparts like ChatGPT and Google's Gemini.
GOVERNMENT
DHS plans to slash HQ workforce, including AI experts
In February 2024, the Department of Homeland Security (DHS) initiated a significant effort to recruit 50 artificial intelligence (AI) experts for its newly established AI Corps, aiming to enhance the agency's capabilities in areas such as countering fentanyl trafficking, combating child sexual exploitation, and improving cybersecurity. By December 2024, DHS had successfully onboarded 39 AI specialists, with additional hires in progress.
However, as of April 2025, DHS is planning substantial workforce reductions within its Management Directorate, targeting approximately 50% cuts. This downsizing includes positions within the AI Corps and the Customer Experience Directorate. These cuts align with directives from DHS leadership to identify and eliminate roles deemed non-essential, reflecting a shift in the department's operational priorities.
