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. The way we measure progress in AI is terrible Every time a new AI model is released, its typically touted as acing its performance against a series of benchmarks. OpenAIs GPT-4o, for example, was launched in May with a compilation of results that showed its performance topping every other AI companys 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 models 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 wayand researchers have some ideas for how they should be improved. Scott J Mulligan 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 theyre 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 peoples 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.

Tommaso Valletti, an economist who worked under the European Unions antitrust regulator Margrethe Vestager, reflects on her legacy as she prepares to step down to the New York Times. The big story How to fix the internet October 2023 Were in a very strange moment for the internet. We all know its broken. But theres 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. Theres a sort of common wisdom that the internet is irredeemably bad. That social platforms, hungry to profit off your data, opened a Pandoras 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, theres still so much good to be found there. And yet, fixing online discourse is the definition of a hard problem. But dont worry.
