# The Download: AI agents, and how to detect a lie

Plus: Chinese EVs have hit an EU-shaped blockade

*This is today's edition of The Download*,* our weekday newsletter that provides a daily dose of what's going on in the world of technology.*

**What are AI agents?**When ChatGPT was first released, everyone in AI was talking about the new generation of AI assistants. But over the past year, that excitement has turned to a new target: AI agents.

Agents featured prominently in Google’s annual I/O conference in May, when the company unveiled its new AI agent called Astra, which allows users to interact with it using audio and video. OpenAI’s new GPT-4o model has also been called an AI agent.

And it’s not just hype, although there is definitely some of that too. Tech companies are plowing vast sums into creating AI agents, and their research efforts could usher in the kind of useful AI we have been dreaming about for decades. Many experts, including Sam Altman, say they are the next big thing. But what are they? And how can we use them? Read the full story.

**AI lie detectors are better than humans at spotting lies**

Can you spot a liar? It’s a question I imagine has been on a lot of minds lately, in the wake of various televised political debates. Research has shown that we’re generally pretty bad at telling a truth from a lie.

Some believe that AI could help improve our odds, and do better than dodgy old fashioned techniques like polygraph tests. AI-based lie detection systems could one day be used to help us sift fact from fake news, evaluate claims, and potentially even spot fibs and exaggerations in job applications. The question is whether we will trust them. And if we should. Read the full story.

**The big storyHow culture drives foul play on the internet, and how new “upcode” can protect us**

From Bored Apes and Fancy Bears, to Shiba Inu coins, self-replicating viruses, and whales, the internet is crawling with fraud, hacks, and scams.

And while new technologies come and go, they change little about the fact that online illegal operations exist because some people are willing to act illegally, and others fall for the stories they tell.

Ultimately, online crime is a human story. But why does it work, and how can we protect ourselves from falling for such schemes? Read the full story.
