In today’s Digest, we cover Musk adding ads to X’s AI chatbot, OpenAI launching GPT-5, and US Secretary of State Marco Rubio ordering a US lobbying blitz against the EU tech law.

Musk to add ads to X’s AI chatbot

Elon Musk is turning to artificial intelligence to revive X’s advertising business, announcing plans to integrate paid ads directly into the answers generated by Grok, the platform’s in-house AI chatbot. 

Speaking during a live session with advertisers on Wednesday, Musk framed the move as a logical step after focusing efforts on making Grok “the smartest, most accurate AI in the world.” 

He added “If a user’s trying to solve a problem [by asking Grok], then advertising the specific solution would be ideal at that point.” 

GPT-5 launches

OpenAI has officially launched GPT-5, a next-generation system designed not just to answer questions, but to act on users’ behalf. GPT-5 combines the deep reasoning abilities of OpenAI’s o-series with the responsiveness of earlier GPT models, making it the first "unified" model from the company. 

With this release, OpenAI shifts focus from simple chatbot interactions toward more autonomous, task-oriented AI agents capable of writing code, managing calendars, and producing research briefs. GPT-5 eliminates the need for users to tweak settings or choose between speed and depth. Instead, it introduces a built-in real-time router that automatically determines how best to respond, opting for quick answers when appropriate, or slowing down to think through more complex queries.

OpenAI CEO Sam Altman called GPT-5 “the best model in the world,” describing it as a major milestone in the company’s path toward artificial general intelligence (AGI), AI that can outperform humans at most economically valuable tasks. “Having something like GPT-5 would be pretty much unimaginable at any previous time in history,” Altman added.

Trump administration orders US lobbying blitz against EU tech law

The Trump administration has directed American diplomats in Europe to actively lobby against the European Union’s Digital Services Act (DSA), branding it a threat to free speech and US tech interests. According to an  internal cable signed by US Secretary of State Marco Rubio, this includes monitoring "any government efforts to suppress protected forms of expression or coerce private companies to do the same,” with a particular focus on incidents affecting US citizens and businesses. 

The State Department’s cable accused the European Union of imposing “undue” restrictions on freedom of expression through its efforts to regulate hate speech, misinformation, and disinformation, arguing that the Digital Services Act (DSA) only deepens these curbs.

The cable instructs US diplomats to actively engage with host governments and digital regulators across Europe, urging them to support amendments or outright repeals of the DSA and similar national laws.
