1. ChatGPT Gets Smarter and Free Users Get More
OpenAI is making another big change to ChatGPT, and this time free users are getting some of the benefits too.

The company has updated GPT-5.6 Sol for paid users, with a focus on giving clearer answers, making fewer mistakes, and handling difficult questions more reliably. Users can also get more control over how much thinking the model uses before answering.
But the more interesting part for everyday ChatGPT users is the free plan. OpenAI is bringing GPT-5.6 Luna to Free and Go users and says unlimited text chats are coming for free accounts. A new Think option is also being added for questions that need more reasoning.
With ChatGPT now used by around a billion people every week, even a small change to the free version can have a huge impact.
For users, the message is simple: ChatGPT is getting more capable without everyone needing to upgrade to a paid plan.

2. OpenAI Slows Astra After Cybersecurity Warning
OpenAI’s next major model, Astra, is showing impressive abilities—but some of those abilities are creating new concerns.

During safety testing, OpenAI found that Astra could become powerful enough to discover and use serious software weaknesses. The company says it cannot yet rule out the possibility that Astra could reach its highest cybersecurity risk level.
Because of that, OpenAI has tightened its safety rules and paused some internal work until stronger protections are in place.
This doesn’t mean Astra has been cancelled. Instead, OpenAI appears to be taking more time to make sure the model can be released safely.
It also shows how quickly AI is changing. A few years ago, the big question was whether AI could write good text. Now companies are testing whether AI systems could independently find weaknesses in real computer systems.

3. Google Shakes Up DeepMind as Big AI Names Leave
Google is making some major changes inside the team responsible for much of its AI work.

Demis Hassabis, who has led Google DeepMind, is moving into a broader role as Alphabet’s chief scientist and DeepMind chairman. Meanwhile, CTO Koray Kavukcuoglu will take on more of the day-to-day leadership.
At the same time, several major Google AI researchers are leaving the company. The group includes well-known names such as Jeff Dean, Sanjay Ghemawat, Oriol Vinyals and Quoc Le, who are moving on to build a new AI company called Discovery Loop.
The changes arrive at an important time for Google. OpenAI, Anthropic and other companies continue to move quickly, while Google is also under pressure to keep Gemini competitive.
Google is still one of the biggest players in AI, but this week shows that even the largest AI teams are changing rapidly as researchers, companies and new startups compete for talent.
