Very interesting. GPT-J is an opensource free alternative to GPT-3 and requires at least 12.1GB memory to run the model (which is reduced from original 48GB ram). But if the model stores some kind of index and does internet searches (or hard drive) instead, then it could scale much further as there is a limit on how much memory you can use in production.

>48GB ram

48GB VRAM? 48+ gigabytes of system ram is cheap, 48 gigabytes of ram on a GPU is still painfully expensive.

I got into a very long debate with an openai person 4/5 years ago about this + adversarial learning + access to a quantum computer (think just straight up world class abacus) was close to the primitives required for more generalized AI. They didn't agree with me, but that's ok! :)

Does anyone know if we understand enough about natural, generally intelligent brains to dismiss the idea that they are using quantum phenomenon for computation? Is it unlikely for any reason?

I believe plenty of "quantum phenomenon" are utilized in humans' biochemistry[0]. Whether the brain "calculates" things using a method that is particularly similar to the methods used in today's quantum computers is...unlikely. It probably is "quantum" in other ways though.

Could someone explain the article to layman engineer?

It's language modelling with search engine in-the-loop. Instead of training GPT-3 with 178B weights, you train a 25x smaller model and allow it to retrieve useful snippets from a large text index as additional information. This solves the problem of very large models and the problem of updating an already trained model, as you can swap the text corpus with a newer one. The model learns mostly syntax, burning less tri…

Yes, the key technology here is a scalable embedding store. The leading players here are the indexes - faiss and scann. The open source platforms are opensearch, elasticsearch, featureform, milvius. Then there are saas products like pinecone.

So the memory doesn't solve the context problem of e.g. "conversation context"? I.e. the storage isn't modified while the model is used? If I make an app that makes conversation using such a model model, then the storage isn't modified to insert knowledge about what the early parts of the conversation was about, and it's only bringing a database of fixed information into the conversation? (I have a friend who is just like that).

Yes, vram

I don't think we know enough to know, I also don't think we know enough to rule it out, to me it's plausible, and that was generally the debate... is a quantum requirement there or not. Also as a note, this was conversation over beers with a buddy, so it wasn't HN scrutiny standard, we were getting philosophical. (I know very little about the subject so my opinions aren't much more than "fun ideas".)

I know AI Dungeon and Novel AI both factor in several recent text inputs when generating new text, and also have a memory section where you can add things you want the AI to never 'forget' about the current story.

> Gebru, a widely respected leader in AI ethics research, is known for coauthoring a groundbreaking paper that showed facial recognition to be less accurate at identifying women and people of color, which means its use can end up discriminating against them.

Surely this is a function of location? I understand the U.S.-English term “person o color” to be convoluted language for “not white”. One simple thing I notice is that if I search for, say, “child” on Google Image Search, the images indeed tend to look as what one would expect from the average inhabitant of an English-speaking nation, when I search “子供”, I indeed mostly see what I would expect from Japan. Similarly, if I search for “house”, what I find tends to look like a house most likely situated in the Netherlands; with “บ้าน”, it does resemble more so stereotypical Thai architecture.

I would assume that a.i.'s made in, say, Japan would yield different results.

That poor researcher.

Thankfully we're very good friends, so it was a few hours well spent over beers (I hope...?)
