Google Chrome will steal 4 GB of disk space from your computer for its local large language model unless you opted out.

It's called weights.bin and it's stored in a folder called OptGuideOnDeviceModel. What's more, if you track down the file and delete it, Chrome will download a fresh copy and reinstate it. //

If you didn't opt out, Google has some info on how to disable it. In brief: in Chrome's address box, enter the special URL chrome://flags. In the resulting page, look for an entry named optimization-guide-on-device-model and set it to Disabled, then restart Chrome. The browser should then delete the weights.bin file. //

The late great Grace Hopper used to hand out 30 cm (roughly 1 foot) lengths of wire as physical examples of a nanosecond: that's how far light can travel in one billionth of a second. If Google considers a 4 GB model to be "nano" sized, then it puts Hanff's hyperbolic comment about the climate footprint into real perspective. It gives a hint of the size of the real gigantic models in the datacenters metastasizing across the world.

A recent study led by Grace Liu at Carnegie-Mellon found that regular AI use caused measurable cognitive impairment. It's worth thinking carefully about what we trade away when we outsource our thinking and, separately, what the planet pays to power the systems we're outsourcing it to.

This vulture suggests you turn it off now, everywhere you can. ®
