AI fingerprints, Cursor crashes & more (July 7, 2025)

Happy Monday!

If AI has strategy and fingerprints, what’s next, a conscience? Today’s stories touch on model personalities, peer review hacks, and antitrust headaches. Let’s dive in👇

🧠 LLMs Are Thinking... Strategically?

🤝 LLMs Show Strategic Intelligence

Researchers ran 140,000 rounds of the Prisoner’s Dilemma with OpenAI, Google, and Anthropic models, and found clear behavioral differences. Gemini was ruthless, OpenAI was friendly (even when it hurt), and Claude was surprisingly forgiving. The big idea? These models aren’t just guessing the next word, they’re reasoning.

🔬 “AI Fingerprints” Found in Millions of Research Papers

New research uncovered that LLM-generated content leaves behind subtle, identifiable linguistic patterns, or “AI fingerprints.” These markers have now been spotted in millions of scientific papers, raising fresh questions about how often AI is ghostwriting academic research. Expect a new wave of authenticity tools and policies.

💻 Cursor Faces Developer Revolt

Cursor’s switch to token-based pricing blew up fast. Users torched their quotas in hours, even on $7K plans, with many migrating to Claude Code. Cursor admitted the rollout was a mess and is issuing refunds. The lesson? Bad communication turns billing tweaks into brand crises.

🕵️‍♂️ AI Gets Tricky

🧪 Peer Reviews Hacked with Invisible Prompts

At least 14 universities were caught sneaking invisible text into papers to manipulate AI peer reviewers into returning only glowing feedback. Institutions like KAIST have pulled papers, while others argue they were just exposing lazy AI-assisted reviewing. Either way, AI in science is looking more like a double-edged sword.

🏛️ Google AI Overview Triggers EU Complaint

A group of European news publishers has filed an antitrust complaint against Google’s AI Overviews. The claim: AI answers scrape and summarize publisher content without compensation, siphoning away traffic. Google says Overviews improve access. but regulators may see it as just another form of monopolistic behavior.

🤝 Capgemini Buys WNS, Bets Big on Agentic AI

Capgemini just announced a $7.6B acquisition of WNS to form a new global leader in intelligent operations. The big goal? Dominating the future of agentic, AI-powered enterprise workflows. As every consulting firm rushes toward the AI goldmine, scale and execution are what will separate the contenders from the vaporware.

🧾 TLDR

LLMs are not only strategic, they’re leaving linguistic fingerprints all over academic research. Meanwhile, Google’s AI Overviews face EU scrutiny, Capgemini drops $7.6B on AI workflows, and developers revolt against Cursor's surprise pricing. In short: AI isn’t just evolving, it’s disrupting science, business, and itself.

👋 Until tomorrow,
