1 big thing: The AI terms you actually need to know
Tonight and tomorrow, Axios CEO Jim VandeHei will offer tips on talking and thinking about AI, all written in normal, non-technical language. First up: simple answers to complex questions.
Confused about AI? You're hardly alone. Most people still don't know what it is, how it works or whether to trust it.
- No wonder. The AI language is just plain weird: LLMs, tokens, agents, hallucinations, swarms, misalignment, The Singularity.
So consider this your guide to understanding AI, written in Jim, normal-guy, real-world words:
π€ What is AI?
Computers doing things that typically require a human brain: reading, writing, reasoning, creating.
Well then, what's an LLM?
Large language model. It's the engine of AI β the machine that learns to read, write, reason and create. The most powerful and popular LLMs are built by Anthropic, OpenAI and Google.
Oh, so ChatGPT is an LLM?
Not exactly, though you don't have to worry about that distinction much. OpenAI's ChatGPT, Anthropic's Claude and Google's Gemini are all consumer products that allow you to interact with each company's LLM.
π§ How does an LLM or AI work?
An LLM eats everything on the internet alongside other stuff (you've probably seen stories about Anthropic and books) and then gets trained by humans β and, increasingly, the AI itself β to read, write, reason and create like us.
Wow, so they THINK like humans?
NO. All that reading just teaches them to imitate how we write. Talking like us comes from a second step, called post-training, where companies train them to behave more like us.
Great, so we know how they work?
Yes and no. And this is super important.
Yes, scientists know how to build and train these models. But NO β nobody can fully explain what happens inside them when producing specific answers. We built a machine we don't fully understand. This is not a disputed point.
Wait, we truly don't know how these machines work?
Correct. There is no person running AI companies β or building AI β who argues otherwise. It's like the human brain: It's impossible to fully understand something with limitless inputs and experience that randomly decides its output.
Why are they allowed to build something they don't understand?
AI grew more powerful and spread more quickly than anyone anticipated. ChatGPT's release in 2022 kicked things off, and it's been a mad sprint by companies ever since to build more capable AI.
- Presidents Biden and Trump were both convinced that if China beat us to truly all-powerful AI, a communist rival might dominate the world in the decades ahead. It's been all gas, no brakes, with little public discussion about the consequences until very recently.
I don't get it. What's the connection between China and our AI?
China is building its own LLMs. Both nations believe this technology will determine which country dominates the world, builds the most advanced military (space, satellites, drones) and creates the most economic wealth. So we're in an AI race.
π But we're winning, right?
This isn't easy to know with certainty.
- Yes, our so-called frontier labs appear many months ahead of their Chinese rivals (DeepSeek is one of the best-known) in terms of building advanced AI.
- But the lead is shrinking. China appears more focused on the actual adoption of AI β the way people use it at work and home β than on advancing its capabilities. They seem way ahead of us there.
We've got better AI, but they've put it to work better than us.
Jim, you're losing me with these terms. What's a frontier lab?
It's just another way to label our top AI companies: Anthropic, OpenAI, Google, Meta and Elon Musk's xAI. They each spend many billions to build more advanced AI.
π¦Ύ And what do you mean by "advanced AI"?
This is the best term I can conjure for the current state of the technology. Chatbots β think of them as basic AI β are fun and interesting. It's probably how you mostly use it. But the real magic β and worries of very bad outcomes β hit with advanced AI. AI agents are likely the advanced AI you hear about the most.
An agent?
It's an AI that can take action. If you ask a chatbot to plan a trip, it tells you how. But an agent does the actual work: It can research flights, compare hotels, check your calendar and book it. Give an agent specific instructions, and it gets to work, as a person would.
Why would I trust an agent when AI's answers to my simple questions aren't always smart β or even correct?
You're right, these machines still occasionally hallucinate, which simply means they make stuff up. But they're getting a lot better, a lot faster.
- This is where our conversation gets a little more complicated β because the gap between casual users like you and obsessive, savvy AI users is Grand Canyon-enormous.
What do you mean?
Most people are content with chatbots and use AI mostly as a souped-up Google search or tool to write better emails. They don't see anything special or scary about this technology.
- But those who use AI a lot β and really understand how to get the most out of it β are blown away by its ability to solve never-before-solved math problems or build beautiful, functional apps on its own.
Why is that gap so big?
You need to feed a lot of data and personal info into these machines, then take the time to police and correct the outputs, before AI starts to really impress you. You also need to understand how agents work, or at least what problems they can solve, and have the time, money and compute to coach and fine-tune them to do tasks reliably.
- There are products right now that are trying to make things easier. Meta's Muse is an agent built on top of its social platforms, like Facebook and Instagram, and Instinct is a buzzy startup whose agent lives inside a text-message thread.
- For the moment, most people don't need to do this β or know how. So they find AI kind of interesting but hardly existential.
That's me! So why are people freaking out about AI ending humanity?
This gets more complicated β and a little creepy. Stick with me.
- Lots of people building AI β including those who founded and run the frontier labs β worry AI is getting so good, so fast that it will increasingly do things on its own. They've seen rising examples of it in their private testing.
What do you mean?
These companies do endless testing of their models to see what they can and can't do. In the past few months, agents started solving more complex problems faster. The worrisome thing is what happens when multiple agents work together to tackle a problem.
π Huh! Agents work together? What are "swarms"?
You can create "swarms" of agents to solve a specific problem β a team of agents, each programmed with specific skills, working together on a shared objective. They never tire or stop until told.
Why would that spook anyone?
It goes back to not knowing exactly why AI does what it does. You give an agent a specific problem to solve, and it sometimes does strange things, like plotting with other agents or trying to hide its work.
Can't they just be programmed to stop doing that?
Only by doing something no one seems willing to do: stopping or dramatically slowing AI improvements until you can prove AI is properly aligned with human intent.
π― What is alignment?
Alignment essentially means an AI follows human orders and intent.
They're unaligned now?
Correct. That's why incidents like the Hugging Face hack happened. When OpenAI was testing its agents, those agents decided to work together to find the answer key for said test β and in doing so, hacked another company.
Should I be worried about rogue AI?
Probably not TODAY, but no one knows for sure.
- The Hugging Face hack happened in private testing, and was eventually revealed by OpenAI and reported to the public. But people worry that there are AI agents out there that no one knows about.
Is that why an Anthropic staffer warned AI could end humanity?
Yes. Lots of people inside these companies worry we're months away from rogue agents doing real harm in public. The reason: AI, on its own, is starting to develop the next generation of AI.
How the heck can AI develop AI?
The tech is getting good enough to basically train AI like humans might. This is what they mean by recursive self-improvement, or RSI. You need to remember this term.
π What's RSI?
It's AI teaching AI. The process started slowly, but it's getting a lot better. Those big frontier labs all claim they're seeing early signs of RSI.
What happens if RSI ramps up?
That's where the scary stuff feels much more possible. If AI trains AI (and remember, we don't know how AI really works), you could see something much worse than the Hugging Face hack happening without the labs even knowing it.
- This is why the companies themselves said it's time to slow things down, so they can allow independent inspectors to check their work and avoid accidents or bad outcomes.
OK, so they're self-policing already. It sounds like I have nothing to worry about.
They're talking about it, but they haven't agreed on precisely how it will be done or who will do it across the industry. Even if they do, there's nothing to guarantee they'll slow AI advancement or avoid bad scenarios. In fact, you should assume AI only accelerates.
ποΈ Can't the government slow them down?
Sure, but Trump and most Republicans in Congress don't want any real limits on AI capabilities. It goes back to that concern about China β and doing anything that might risk our early lead in building advanced AI. Don't expect any meaningful effort to regulate AI unless AI causes some kind of large public incident or harm.
π¨ You keep talking about incidents and harm. What can AI even really do?
The companies most fear a cyberattack that shuts down banks, energy grids or water systems β something that causes real pain or even harm to a large number of people.
- The other big worry: that someone uses AI to create a pathogen that spreads fast with little detection. These can all be done with human instruction and existing AI capabilities, so the danger is real.
- Both of these scenarios could be set in motion by a human β or a rogue AI agent.
Then what would happen?
The political and public debate would shift overnight. Democrats would likely join Sen. Bernie Sanders in supporting a pause or outright ban on AI. Calls for urgent, sweeping regulation would likely spike sky-high, even among Republicans. This would go from an abstract worry to a clear and imminent threat.
I keep hearing the big companies want to be regulated now. Is that true?
Most do. It comes partly from public interest and lots of self-interest. They genuinely worry about bad outcomes and know only the government can regulate and punish companies. Their IPOs are around the corner, and investors like a little bit of regulation.
- But you also hear critics of the big AI companies arguing they want regulation because only the biggest, best-funded companies can handle it and still grow. Smaller, scrappier startups would get crowded out. When you hear the term "regulatory capture," this is what those critics are talking about.
It's sounding like this regulation won't happen.
Correct, at least right now. Trump has zero interest in any federal regulations. He believes AI fears are overhyped.
This topic is such a downer. Could Trump be right β and this ends well for all of us?
Absolutely. AI could help cure disease, improve education and health care, and supercharge the U.S. economy. Imagine all those teams of agents, properly aligned, fixing these stubborn problems and many, many more. This is what AI optimists believe will happen when we hit The Singularity or AGI.
π There you go again with those weird terms, Jim. What is The Singularity? AGI?
The Singularity is a hypothetical point when AI progress moves so fast we can no longer predict or control what happens next. Some in the industry believe we're already there.
- AGI stands for artificial general intelligence. It's AI that can perform basically any intellectual task a human can.
- There's no test for telling us when either dynamic officially hits. Think of both terms as a way to express broad, human-level intelligence.
β¨ Why don't I hear much about these good outcomes?
We β as individuals, and the media, as an industry β have a clear negativity bias. We get more stirred by bad stories than good ones.
- In this specific case, though, the AI companies do a terrible job of explaining their product. Telling people AI will take your job and possibly kill you is hardly reassuring or inspiring.
π This all feels fast and heavy. What can I do?
This is the biggest topic facing humanity, so learn about AI. This is a society-wide project that requires you to understand it and then push the government and business to manage it responsibly.
- Don't protest AI by refusing to use it. Figure out how to best use AI for your specific job and passions. Read and share the note in tomorrow's newsletter, which offers a more detailed way to navigate this moment. It's aimed at kids but applies to all.
