The Download: rethinking AI benchmarks, and the ethics of AI agents
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.
The way we measure progress in AI is terrible
Every time a new AI model is released, it’s typically touted as acing its performance against a series of benchmarks. OpenAI’s GPT-4o, for example, was launched in May with a compilation of results that showed its performance topping every other AI company’s latest model in several tests.
The problem is that these benchmarks are poorly designed, the results hard to replicate, and the metrics they use are frequently arbitrary, according to new research. That matters because AI models’ scores against these benchmarks determine the level of scrutiny they receive.
AI companies frequently cite benchmarks as testament to a new model’s success, and those benchmarks already form part of some governments’ plans for regulating AI. But right now, they might not be good enough to use that way—and researchers have some ideas for how they should be improved.

We need to start wrestling with the ethics of AI agents
Generative AI models have become remarkably good at conversing with us, and creating images, videos, and music for us, but they’re not all that good at doing things for us.
AI agents promise to change that. Last week researchers published a new paper explaining how they trained simulation agents to replicate 1,000 people’s personalities with stunning accuracy.
AI models that mimic you could go out and act on your behalf in the near future. If such tools become cheap and easy to build, it will raise lots of new ethical concerns, but two in particular stand out. Read the full story.

The big story
How to fix the internet
October 2023
We’re in a very strange moment for the internet. We all know it’s broken. But there’s a sense that things are about to change. The stranglehold that the big social platforms have had on us for the last decade is weakening.
There’s a sort of common wisdom that the internet is irredeemably bad. That social platforms, hungry to profit off your data, opened a Pandora’s box that cannot be closed.
But the internet has also provided a haven for marginalized groups and a place for support. It offers information at times of crisis. It can connect you with long-lost friends. It can make you laugh.
The internet is worth fighting for because despite all the misery, there’s still so much good to be found there. And yet, fixing online discourse is the definition of a hard problem. But don’t worry. I have an idea. Read the full story.
