Doesn't help when the ads are a layer above the model.

There are open source models you yourself or a trusted third party can run. No ads.

You can save an open source + open weights model, which is frozen in time. That’s still very useful for some things but lacks knowledge of current data.

So we’ll end up with a choice of low-performing stale models or high-performing enshittified models which know about more current information.

Open source models get updated all the time. You'd only be a few months behind.

Direct enshittification is intentional and wouldn’t affect open models.

Indirect pollution via AI slop in the input and the same content manipulation mechanisms as SEO hacking is still a threat for open models.

Really? I thought you could only do that with open source models. Can you teach me how to checkpoint the current version of Claude Code so I can keep it as-is forever?

Yup. Like Claude 3 Opus.
