That's because this isn't something coming from the AI itself. All the people blaming the AI or calling this a "hallucination" are misunderstanding the cause of the glue pizza thing.

The search result included a web page that suggested using glue. The AI was then told "write a summary of this search result", which it then correctly did.

Gemini operating on its own doesn't have that search result to go on, so no mention of glue.

Not quite, it is an intelligent summary. More advanced models would realize that is bad advice and not give it. However for search results, google uses a lightweight, dumber model (flash) which does not realize this.

I tested with rock example, albiet on a different search engine (kagi). The base model gave the same answer as google (ironically based on articles about google's bad results, it seems it was too dumb to realize that the quotations in the articles were examples of bad results, not actual facts), but the more advanced model understood and explained how the bad advice had been spreading around and you should not follow it.

It isn't a hallucination though, you're right about that

[–] TrickDacy 10 points 4 months ago (1 children)

the more advanced model

Can you explain what this is?

[–] [email protected] 7 points 4 months ago (1 children)

There are 3 options. You can pick 2.

  1. Good
  2. Cheap
  3. Fast

Google, as with most businesses, chose option 2 and 3.

[–] TrickDacy 10 points 4 months ago (1 children)

I understand this, the user had said it like you can just switch to "advanced AI mode" at will, which I'm curious about.

[–] [email protected] 6 points 4 months ago (1 children)

Yeah it's called the "research assistant" I think. Uses GPT4-o atm.

Big AI trying very hard to hide the truth about glue in pizza.

[–] [email protected] 15 points 4 months ago

Fucksmith showed us the way!

[–] Eheran 51 points 4 months ago

Or they made sure to fix it ASAP like Google did too.

[–] [email protected] 35 points 4 months ago (2 children)

You just haven’t gaslighted your ai into saying the glue thing. If you keep trying by saying things like “what about non-toxic glue” or “aren’t there glues designed for humans” the ai will finally give in and recommend the glue. Don’t give up. Glue is good for us.

[–] [email protected] 28 points 4 months ago

Glue is what keeps us together!

Well, they manually removed that one. But there are much better ones:

[–] Ghostalmedia 27 points 4 months ago (2 children)

I imagine Google was quick to update the model to not recommend glue. It was going viral.

[–] franklin 8 points 4 months ago* (last edited 4 months ago) (1 children)

Main issue is Gemini traditionally uses it's training data and the version answering your search is summarising search results, which can vary in quality and since it's just a predictive text tree it can't really fact check.

[–] balder1991 5 points 4 months ago (1 children)

Yeah when you use Gemini, it seems like sometimes it’ll just answer based on its training, and sometimes it’ll cite some source after a search, but it seems like you can’t control that. It’s not like Bing that will always summarize and link where it got that information from.

I also think Gemini probably uses some sort of knowledge graph under the hoods, because it has some very up to date information sometimes.

[–] [email protected] 3 points 4 months ago

I think copilot is way more usable than this hallucination google AI…

[–] efstajas 3 points 4 months ago* (last edited 4 months ago)

You can't just "update" models to not say a certain thing with pinpoint accuracy like that. Which one of the reasons why it's so challenging to make AI not misbehave.

[–] eager_eagle 21 points 4 months ago

Absolutely not! You should use something safe for consumption, like bubble gum.

These are statistical models, meaning that you'll get a different answer each time, also different answers based on context.

[–] BradleyUffner 10 points 4 months ago (2 children)

Not exactly. The answers would be exactly the same given the exact same inputs if they didn't intentionally and purposefully inject some random jitter into the algorithm each time specifically to avoid getting the same answer each time

[–] [email protected] 10 points 4 months ago (1 children)

It’s not just random jitter, it also likely adds context, including the device you’re using, other recent queries, and your relative location (like what state you’re in).

I don’t work for Google, but I am somewhat close to a major AI product, and it’s pretty much the industry standard to give some contextual info to the model in addition to your query. It’s also generally not “one model”, but a set of models run in sequence— with the LLM (think chatGPT) only employed at the end to generate a paragraph from a conclusion and evidence found by a previous model.

[–] BradleyUffner 4 points 4 months ago

I consider "context", even if not added explicitly by the user, to be part of the input.

[–] [email protected] 1 points 4 months ago (1 children)

That jitter is automatically present because different people will get different search results, so it's not really intentional or purposeful

[–] [email protected] 4 points 4 months ago (1 children)

Yes it is intentional.

Some interferences even expose a way to set the "temperature" - higher values of that mean more randomized (feels creative) output, lower values mean less randomness. A temperature of 0 will make the model deterministic.

[–] [email protected] 1 points 4 months ago (1 children)

even at 0 temperature the model will not be deterministic, because it depends on the seed used as well as things like numerical noise.

[–] [email protected] 1 points 4 months ago* (last edited 4 months ago) (1 children)

Yeah no, that's not how this works.

Where in the process does that seed play a role and what do you even mean with numerical noise?

Edit: I feel like I should add that I am very interested in learning more. If you can provide me with any sources to show that GPTs are inherently random I am happy to eat my own hat.

[–] [email protected] 1 points 4 months ago (2 children)

https://github.com/ollama/ollama/blob/main/docs/api.md#request-reproducible-outputs

LLMs are prompted with a seed. If you change the seed you get a different answer.

[–] [email protected] 1 points 4 months ago

Addendum:

The docs say

For reproducible outputs, set temperature to 0 and seed to a number:

But what they should say is

For reproducible outputs, set temperature to 0 or seed to a number:

Easy mistake to make

[–] [email protected] 1 points 4 months ago

I appreciate the constructive comment.

Unfortunately the API docs are incomplete (insert obi wan meme here). The seed value is both optional and irrelevant when setting the temperature to 0. I just tested it.

[–] [email protected] 9 points 4 months ago

Ask it five times if it is sure. You can usually get it to say outrageous things this way

[–] [email protected] 8 points 4 months ago (1 children)

I'm almost sure that they use the same model for Gemini and for the A"I" answers, so patching the "put glue on pizza" answer for one also patches it for another.

[–] balder1991 3 points 4 months ago

Nope it’s because on Search it was summarizing the first results, the “pure Gemini” isn’t doing a search at that time, it’s just answering based on what it knows.

Ive been experimenting with using search as a tool and the capability write and execute code for calculations. https://github.com/muntedcrocodile/Sydney

[–] nutsack -5 points 4 months ago (1 children)

it has been quite broken for some time
