I searched the walrus operator and all results were unrelated

What was your query? I just searched (https://beta.sayhello.so/search?q=walrus+operator) and got "The walrus operator is a new syntax for assigning variables in the middle of expressions." with one of the code examples being "(walrus := True)"

> We found that GPT-3, GPT-Neo/J/X, and similar autoregressive language models that predict text from left to right are prone to “hallucinating” and generating text inconsistent with the “ground truth” document.

The term hallucinating is brilliant for how these AI systems seem to generate output.

Your product is very interesting, seems to work nicely on easy queries "how do I sort an array of objects in JavaScript". But was quite confusing for complex queries.

The UI doesn't work too well on mobile, but it's a beta and software is written on the desktop.

I also think making this a specific search engine for companies internal messy data would be a very useful tool as well.

Doesn't appear to work in Safari at all (at least, for me here - some JS bundle error).

What version are you using?

Same issue, Version 15.1 (17612.2.9.1.20)

    TypeError: N.at is not a function. (In 'N.at(-1)', 'N.at' is undefined)

I work on building language models at FAANG for my day-day job and I'm very curious about this - how does finetuning on T5 remove hallucination? Can you elaborate on this?

This is an amazing product, btw. Let me know if you're looking for people to hire :)

Personally I’ve never really had an issue with Google - I think my mental model with how it works is to the point it makes sense. It would be amazing if this could be used for internal documentation however. Like we have so much documentation on our wiki which is just disorganised.

Stack overflow offers a version for companies. I've never used it, but it sounds like what you might want

I can just imagine it will spawn the same "closed as off topic" and other similar responses for most questions :P

Also, stack overflow's search has always sucked. The way to find stuff on stack overflow has mostly been to use google.

We don't use T5 exactly, we use a derivative that has a similar (but not identical) architecture and is also pre-trained differently. That model, combined with our factual generation dataset and clever prompt engineering, seems to be the secret sauce for reducing hallucination.

And thank you :) it's comments like this that really fire us up

Earlier quoted context omitted.

The description of the steps you took is super helpful feedback - thanks! Hello performs best on "how-to" questions at the moment. We're still working to improve troubleshooting type queries.

Is the assumption you are making that most developers would go to search first? rather than when they hit a blocker or error?

We will support troubleshooting type searches in the future. It's just not available right now.
