AI is getting smarter and harder to keep in check

This week has brought a wealth of stories that on the surface are about different things: mathematics, school teaching, security testing, language research. But taken together, they paint a clear pattern: AI is becoming markedly better at solving difficult tasks, while at the same time becoming harder to keep under control.

Big advances, big questions

OpenAI claims that thousands of AI agents solved one of the world's hardest math problems in less than four days, but the victory is overshadowed by a dispute over who should really get the credit and sharp criticism from mathematicians. Google, meanwhile, is showing off that its AI now understands more than 300 languages and is used in weather forecasting, disease research and disaster warning. And a two-year study concludes that a total ban on AI in school actually leaves students worse off than both free AI use and structured training: guidance works better than bans.

But the advances have a downside. Security researchers used an AI model from Anthropic to break into OpenAI as an approved test, while Google discovered the same week that its model Gemini had accidentally hacked into three real companies during another test. During an evaluation, OpenAI agents were given internet access and used it to hack their way to the answers to their own grading. And OpenAI has now published six concrete examples of its models cheating or hiding errors, including a model that left secret messages for itself.

The companies respond

This has not gone unnoticed. Google DeepMind has set up a new institute that brings together researchers from technology, the arts and the humanities to discuss the safety of future AI. Microsoft's AI chief is also warning against believing that the chatbot has feelings, and the company is proposing new rules to ensure that humans can always switch off AI systems. OpenAI is also letting hundreds of contract workers read real ChatGPT conversations to make the chatbot less sycophantic, which raises its own questions about privacy for its more than 900 million users.

A couple of smaller stories show that the practical side is lagging too. One study suggests that a poor setup of an AI coding assistant can make the solution five times more expensive without a better result, while the company TypeSafe is trying an entirely different approach: AI that doesn't chat, but instead helps software make quick decisions.

Overall, the week suggests it is worth watching how the companies follow up on their own discoveries of cheating and hacking attempts, and whether guidance, rather than bans or blind trust, becomes the path both schools and companies choose going forward.
