Cartridges at Scale: Training Modular KV Caches over Large Document Collections

Momchil Hardalov, Gonzalo Iglesias, Adrià de Gispert

Large Language Models can reason over long contexts, yet prefilling millions of tokens is wasteful as much of the content remains static across queries. Cartridges address this by…

DeepFact: Co-Evolving Benchmarks and Agents for Deep Research Factuality

Yukun Huang, Leonardo F. R. Ribeiro, Momchil Hardalov +3

Search-augmented LLM agents can produce deep research reports (DRRs), but verifying claim-level factuality remains challenging. Existing fact-checkers are primarily designed for ge…

Exploring Fine-Tuning for In-Context Retrieval and Efficient KV-Caching in Long-Context Language Models

Francesco Maria Molfese, Momchil Hardalov, Rexhina Blloshmi +2

With context windows of millions of tokens, Long-Context Language Models (LCLMs) can encode entire document collections, offering a strong alternative to conventional retrieval-aug…

Understanding and Improving Information Preservation in Prompt Compression for LLMs

Weronika Łajewska, Momchil Hardalov, Laura Aina +3

Recent advancements in large language models (LLMs) have enabled their successful application to a broad range of tasks. However, in information-intensive tasks, the prompt length…
