Last Translation Benchmark

Vilém Zouhar, Niyati Bafna, Mukund Choudhary +263

For scientific progress, we need benchmarks that test the limits of state-of-the-art models, and evaluation methods that inform us about failure cases. As models get stronger, stan…

Who Flips? Self- and Cross-Model Counterarguments Reveal Answer Instability in LLMs

Nafiseh Nikeghbal, Amir Hossein Kargaran, Shaghayegh Kolli +1

Standard accuracy benchmarks evaluate whether large language models (LLMs) reach correct answers. However, they do not test whether models maintain that answer when challenged by a…

GlotOCR Bench: OCR Models Still Struggle Beyond a Handful of Unicode Scripts

Amir Hossein Kargaran, Nafiseh Nikeghbal, Jana Diesner +2

Optical character recognition (OCR) has advanced rapidly with the rise of vision-language models, yet evaluation has remained concentrated on a small cluster of high- and mid-resou…

CoBia: Constructed Conversations Can Trigger Otherwise Concealed Societal Biases in LLMs

Nafiseh Nikeghbal, Amir Hossein Kargaran, Jana Diesner

Improvements in model construction, including fortified safety guardrails, allow Large language models (LLMs) to increasingly pass standard safety checks. However, LLMs sometimes s…

FineWeb2: One Pipeline to Scale Them All -- Adapting Pre-Training Data Processing to Every Language

Guilherme Penedo, Hynek Kydlíček, Vinko Sabolčec +7

Pre-training state-of-the-art large language models (LLMs) requires vast amounts of clean and diverse text data. While the open development of large high-quality English pre-traini…

How Programming Concepts and Neurons Are Shared in Code Language Models

Amir Hossein Kargaran, Yihong Liu, François Yvon +1

Several studies have explored the mechanisms of large language models (LLMs) in coding tasks, but most have focused on programming languages (PLs) in a monolingual setting. In this…

Tracing Multilingual Factual Knowledge Acquisition in Pretraining

Yihong Liu, Mingyang Wang, Amir Hossein Kargaran +5

Large Language Models (LLMs) are capable of recalling multilingual factual knowledge present in their pretraining data. However, most studies evaluate only the final model, leaving…

On Relation-Specific Neurons in Large Language Models

Yihong Liu, Runsheng Chen, Lea Hirlimann +6

In large language models (LLMs), certain \emph{neurons} can store distinct pieces of knowledge learned during pretraining. While factual knowledge typically appears as a combinatio…

GlotCC: An Open Broad-Coverage CommonCrawl Corpus and Pipeline for Minority Languages

Amir Hossein Kargaran, François Yvon, Hinrich Schütze

The need for large text corpora has increased with the advent of pretrained language models and, in particular, the discovery of scaling laws for these models. Most available corpo…

Glot500: Scaling Multilingual Corpora and Language Models to 500 Languages

Ayyoob Imani, Peiqin Lin, Amir Hossein Kargaran +8

The NLP community has mainly focused on scaling Large Language Models (LLMs) vertically, i.e., making them better for about 100 languages. We instead scale LLMs horizontally: we cr…
