What's the chance that these limericks are now in the training set? As others mention, it'd be interesting to come up with a way to synthesize something sufficiently interesting so it always evades training fit.

Earlier quoted context omitted.

I tested the LLMs to make sure they could not answer the questions unless the limerick was given to them. Other than 4o, they do very badly on this benchmark, so I don't think the test is invalidated by their training.

Why wouldn't it still be invalidated by it if it was indeed trained on it? The others may do worse and may or may not have been trained on it, but them failing on ititself doesn't imply 4o can do this well without the task being present in the corpus.

It can't answer the questions without the limericks in the prompt. The benchmark is to establish how well it uses the context window. For example, I just asked it "What is sought by the English top brass?". The answer from the limerick is "Cranberry glass" and 4o answers correctly when given the associated limerick once out of 2500+ limericks.

However, without the limerick, 4o responded with: "The term "English top brass" typically refers to high-ranking officials or leaders within the British government, military, or other institutions. What they seek can vary widely depending on the context and the specific goals of their roles. Here are some general pursuits that might be sought by such individuals:

National Security: Ensuring the safety and security of the United Kingdom from internal and external threats is a primary concern. This involves defense strategies, intelligence operations, and counter-terrorism efforts.

Economic Stability: High-ranking officials often focus on policies and initiatives aimed at maintaining and improving the country’s economic health. This includes managing inflation, unemployment, trade relations, and economic growth.

Political Influence: Top brass often seek to maintain or expand their influence both domestically and internationally. This can involve diplomacy, forming alliances, and participating in international organizations like the United Nations or NATO.

Social Cohesion: Ensuring social stability and addressing issues such as inequality, healthcare, education, and social services are critical. This can involve implementing policies that promote social welfare and cohesion.

Public Policy Implementation: Leaders are responsible for developing and implementing policies that reflect the government’s priorities. This includes legislation, regulatory frameworks, and public administration.

Technological Advancement: Keeping the nation at the forefront of technological innovation is often a priority. This includes investments in research and development, supporting tech industries, and ensuring cybersecurity.

Environmental Sustainability: Addressing climate change and promoting sustainable practices are increasingly important. This includes policies aimed at reducing carbon emissions, protecting natural resources, and transitioning to renewable energy sources.

Cultural and Heritage Preservation: Protecting and promoting the country’s cultural heritage and national identity can also be a focus. This includes supporting the arts, preserving historical sites, and promoting cultural initiatives.

These pursuits are shaped by the current political climate, global trends, and the specific priorities of the leaders in question. Would you like more detailed information on any of these areas?"

You need to know that this test set data wasn't included in the training data for this to be meaningful.

No you don't. Compare the model's performance before and after uploading the material.

Well, I can now use GPT to transform raw dynamic data into beautiful HTML layouts on the fly for low-traffic pages, such as change/audit logs, saving a ton of development time and keeping my HTML updated even when the data structure has changed. My last attempt did not consistently work because GPT4-Turbo sometimes ignored the context and instructions almost entirely.

Do you have an example of this? I would love to learn more.

I guess you just need to offer a template in the prompt? Then maybe some validation after.

Maybe if you tell it to pull the answer from a limerick instead of generally asking?

Edit: Ok no, I tried giving it a whole bunch of hints, and it was just making stuff up that was completely unrelated. Even directly pointing it at the original dataset didn’t help.

I'd like to see this for Gemini Pro 1.5 -- I threw the entirety of Moby Dick at it last week, and at one point all books Byung Chul-Han has ever published, and it both cases it was able to return the single part of a sentence that mentioned or answered my question verbatim, every single time, without any hallucinations.

A number of people in my lab do research into long context evaluation of LLMs for works of fiction. The likelihood is very high that Moby Dick is in the training data. Instead the people in my lab have explored recently published books to avoid these issues. See BooookScore ( https://openreview.net/forum?id=7Ttk3RzDeu ) which was just presented at ICLR last week and FABLES ( https://arxiv.org/abs/2404.01261 ) a recen…

I’m not involved in the space, but it seems to me that having a model, in particular a massive model, exposed to a corpus of text like a book in the training data would have very minimal impact. I’m aware that people have been able to return data ‘out of the shadows’ pf the training data but to my mind a model being mildly influenced by the weights between different words in this text hardly constitute hard recall, if anything it now ‘knows’ a little of the linguistic style of the authour.

How far off am I?

This sounds dumb - but what if you give it all the limericks MINUS the one you want it to answer about?

I think it will fail, but this actually seems like the cleanest way to demonstrate it.
