The website does a bad job explaining what its current state actually is. Here's the GitHub repo's explanation:

Memory Cache is a project that allows you to save a webpage while you're browsing in Firefox as a PDF, and save it to a synchronized folder that can be used in conjunction with privateGPT to augment a local language model.

So it's just a way to get data from browser into privateGPT, which is:

PrivateGPT is a production-ready AI project that allows you to ask questions about your documents using the power of Large Language Models (LLMs), even in scenarios without an Internet connection. The project provides an API offering all the primitives required to build private, context-aware AI applications.

So basically something you can ask questions like "how much butter is needed for that recipe I saw last week?" and "what are the big trends across the news sites I've looked at recently?". But eventually it'll automatically summarize and data mine everything you look at to help you learn/explore.

Neat.

I thought they're trying to reinvent in-memory key-val storage meant for caching.

Interesting project. Terrible name.

This thing sounds mostly like a way to explore the possibilities with AI. Which I'm all for.

It sounds like it will learn from what you do in your browser, and as we are humans and therefore have alot of habits, then we might find this tool useful!

what in the actual fuck is this stupid shit and why is mozilla anywhere near it?

We're not breaking ground on AI innovation (in fact, we're using an old, "deprecated" file format from a whole six months ago)

The ggml format isn't "deprecated" it's completely dead. In those 6 months we've also seen 2-4x speedups on some systems, not to mention improved accuracy via kquants. I don't know why they would build out a new extension with such an ancient dependency.

I've been holding back my Mozilla funding because they are shirking work on Firefox and Servo

This seems interesting.
