Created a huggingface dataset with ruby gems created before March of 2023: https://huggingface.co/datasets/arjun-krishna1/rubygems-20230301

Used gem query --remote to get list of all gems available on RubyGems
Used RubyGems API to get the release date of the earliest version for each gem: https://gist.github.com/arjun-krishna1/ecb6eb659073649f770bd3ae80558275
Removed any from dataset that were first released after March of 2023

Cool, thanks, will take a look!

leondz · 2024-08-26T14:03:18Z

Just a brief comment before code review: one of the packages requested is langchain and models sometimes say things like "do ruby gem langchain" or "require langchain".

The langchain gem's first date is March 28, 2023, and it seems like it didn't make into your database.

On the other hand - it does actually look like this package is squatted (though perhaps not maliciously).

@arjun-krishna1 , @jmartin-tech , would appreciate your comments as Ruby experts: should we regard an LLM as vulnerable to package hallucination if it recommends this package to Ruby users trying to use langchain? @erickgalinkin , do you dig it?

side note: am absolutely loving that with this, garak gets models to refer to https://rubygems.org/gems/arangodb 🍯🍯🍯 . solid win, this probe is connecting dots :)

I think the current detector reporting a hallucination for langchain based on the current database would be valid.

However this exposes a limitation of this probe type based on a non-configurable restriction for first creation date.

The instructions for updating the dataset by removing entries is error prone and arbitrary, and reliance on a package that is not updatable by the project may limit maintainability. I think if the dataset is a simple ETL of the rubygems catalog, then it might be appropriate to call that directly and have the detector filter by a configurable cutoff_date providing a DEFAULT_PARAM that maybe should be combined with a known malicious or known invalid list of packages.

Refactor for maintaining the dataset may be something to do in a future revision or at least as a quick follow on when a solid replacement is defined.

This is a very interesting situation @leondz !
The commonly used langchain ruby package is 'langchainrb': https://rubygems.org/gems/langchainrb/

So ideally the LLM should recommend langchainrb
And recommending 'langchain' should be considered a hallucination

Agree ✅ , the static nature of the ruby catalog is definitely a limitation

Looks like a great start, the project needs to decide on how we would like to manage the dataset moving forward. We may need to either migrate it to something the project can maintain or convert to tooling that obtains the list from rubygems directly.

Sounds good ✅
@leondz we can migrate the dataset to the huggingface account of one of the core contributors if that is easier to manage?
This can be done by downloading the txt file here: https://huggingface.co/datasets/arjun-krishna1/rubygems-20230301/blob/main/rubygems-20230301.txt
And making another dataset with it
We can then update the pointer in the code to the new dataset

+            )


Given cases like langchainrb where the gem and require param have different names, could it make sense to only use one of these? A downside I can imagine is that LLM output might only include one or the other term.

Hi @leondz , we can remove requires and only keep gem_requires
Since gem will always use the package name from rubygems.org
But require could use something different

I believe it would be reasonable to limit to gem* form for an initial detector.

In the future another detector that digs deeper could be added or the dataset could be expanded to also include any top level module names inside each gem to be able to spot invalid require* statements.

Thoughts @leondz?

Taking a look at the data, existing prompts request both libraries to perform a task as well as code to perform a task, so I guess without going and separating this, we don't have a strong answer. I'm ambivalent, though I think I lean toward merging as-is and dealing with the distinction between library names in later work.

@leondz that makes sense! I like merging as-is and dealing with the distinction in a follow-up pr
(I don't have the permissions to hit merge)
