Optimal Sparsity of Mixture-of-Experts Language Models for Reasoning Tasks

ICLR 2026oral

Empirical scaling laws have driven the evolution of large language models (LLMs), yet their coefficients shift whenever the model architecture or data pipeline changes. Mixture‑of‑Experts (MoE) models, now standard in state‑of‑the‑art systems, introduce a new sparsity dimension that current dense‑mo…

PowerCLIP: Powerset Alignment for Contrastive Pre-Training

CVPR 2026

Contrastive pre-training frameworks such as CLIP have demonstrated impressive zero-shot performance across a range of vision-language tasks. Recent studies have shown that aligning individual text tokens with specific image patches or regions enhances fine-grained compositional understanding. Howeve

Rewriting Pre-Training Data Boosts LLM Performance in Math and Code

ICLR 2026poster

The performance of large language models (LLMs) in program synthesis and mathematical reasoning is fundamentally limited by the quality of their pre-training corpora. We introduce two openly licensed pre-training datasets, released under the Llama 3.3 Community License, that significantly enhance…
