Goodfire Researcher Claims LLM Interpretability Is Easier Than Thought

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

“We were looking at it wrong”: The explosive claim that’s upended the AI world

“I think I have good news about the nature of neural networks.” With those simple words of optimism, Nick Cammarata, a researcher at AI startup Goodfire, kicked off a 26,000-word blog post that has knocked the AI world on its head, sparking wild speculation as well as cautious (and not-so-cautious) celebration.

Cammarata claims that LLMs might be far easier to understand, and thus to monitor and control, than people previously thought. If true, it’s a huge deal. But not everyone is convinced.

I talked to Cammarata the day after his post blew up. We discussed what he thinks researchers are getting wrong, what his work actually shows, and why skeptics aren’t ready to celebrate just yet.

Read the exclusive interview to find out what Cammarata’s claims could mean for AI.

Making the internet better for AI agents might make it worse for everyone else

Until recently, you could split internet users into just two categories: bots and people. But personal AI agents are slowly but surely disrupting that divide by taking on online tasks, from booking flights to reserving hotel rooms. Meta’s Muse alone was downloaded 5 million times in its first month.

The mingling of these agents with human visitors—on an internet designed largely to prioritize people—has gone poorly, with many websites blocking AI agents.

If that demand keeps rising, the internet could be redesigned for agents rather than people. Find out what that could mean for the rest of us.

10 Climate Tech Companies to Watch: Moment Energy and its work to repurpose used EV batteries

Moment Energy is one of MIT Technology Review’s10 Climate Tech Companies to Watch 2026, available exclusively to subscribers.

Demand for energy storage is surging, with capacity expected to grow eightfold in the next decade. To meet that demand, Moment Energy wants to shortcut a supply chain that now flows largely through China by domestically repurposing EV batteries into new grid-connected storage systems.

Ongoing trade battles between the US and China have been a shot in the arm for the company. And soon, it will be able to categorize its repurposed batteries as domestic products in both Canada and the US, where it’s building its next plant.

Learn more about how Moment stands to gain from the current climate.

Quote of the day

**“**They all truly hate each other, and they’re all trying to make as much money as they can as fast as they can.”

—JB Pritzker, governor of Illinois, tells The Verge that the fierce competition between AI companies is complicating efforts to regulate the industry.

One more thing

Is fake grass a bad idea? The AstroTurf wars are far from over.

In 2001, Americans installed just over 7 million square meters of synthetic turf. By 2024, that number was 79 million square meters—enough to carpet all of Manhattan and then some. The increase worries folks who study microplastics and environmental pollution.

While the plastic-making industry insists that synthetic fields are safe if properly installed, lots of researchers think that isn’t so. Find out why AstroTurf has ignited heated debates.
