BidirLM: From Text to Omnimodal Bidirectional Encoders by Adapting and Composing Causal LLMs

Nicolas Boizard, Théo Deschamps-Berger, Hippolyte Gisserot-Boukhlef +2

Transforming causal generative language models into bidirectional encoders offers a powerful alternative to BERT-style architectures. However, current approaches remain limited: th…

Scale or Reason? A Compute-Equivalent Analysis of Reasoning Distillation

Nicolas Boizard, Hippolyte Gisserot-Boukhlef, Kevin El Haddad +2

Distilling reasoning traces from strong teacher models has become the standard recipe for building capable small language models. Yet reasoning traces are 5-20 longer than…

Should We Still Pretrain Encoders with Masked Language Modeling?

Hippolyte Gisserot-Boukhlef, Nicolas Boizard, Manuel Faysse +5

Learning high-quality text representations is fundamental to a wide range of NLP tasks. While encoder pretraining has traditionally relied on Masked Language Modeling (MLM), recent…

Context is Gold to find the Gold Passage: Evaluating and Training Contextual Document Embeddings

Max Conti, Manuel Faysse, Gautier Viaud +3

A limitation of modern document retrieval embedding methods is that they typically encode passages (chunks) from the same documents independently, often overlooking crucial context…

EuroBERT: Scaling Multilingual Encoders for European Languages

Nicolas Boizard, Hippolyte Gisserot-Boukhlef, Duarte M. Alves +16

General-purpose multilingual vector representations, used in retrieval, regression and classification, are traditionally obtained from bidirectional encoder models. Despite their w…

ColPali: Efficient Document Retrieval with Vision Language Models

Manuel Faysse, Hugues Sibille, Tony Wu +4

Documents are visually rich structures that convey information through text, but also figures, page layouts, tables, or even fonts. Since modern retrieval systems mainly rely on th…

Towards Trustworthy Reranking: A Simple yet Effective Abstention Mechanism

Hippolyte Gisserot-Boukhlef, Manuel Faysse, Emmanuel Malherbe +2

Neural Information Retrieval (NIR) has significantly improved upon heuristic-based Information Retrieval (IR) systems. Yet, failures remain frequent, the models used often being un…

Towards Cross-Tokenizer Distillation: the Universal Logit Distillation Loss for LLMs

Nicolas Boizard, Kevin El Haddad, Céline Hudelot +1

Deploying large language models (LLMs) of several billion parameters can be impractical in most industrial use cases due to constraints such as cost, latency limitations, and hardw…
