Mixture-of-Experts Can Surpass Dense LLMs Under Strictly Equal Resource

ICLR 2026oral

Mixture-of-Experts (MoE) language models dramatically expand model capacity and achieve remarkable performance without increasing per-token compute. However, can MoEs surpass dense architectures under strictly equal resource constraints — that is, when the total parameter count, training compute, an…

MVU-Eval: Towards Multi-Video Understanding Evaluation for Multimodal LLMs

NeurIPS 2025poster

The advent of Multimodal Large Language Models (MLLMs) has expanded AI capabilities to visual modalities, yet existing evaluation benchmarks remain limited to single-video understanding, overlooking the critical need for multi-video understanding in real-world scenarios (e.g., sports analytics and a…

Multi-matrix Factorization Attention

ACL 2025finding

We propose novel attention architectures, Multi-matrix Factorization Attention (MFA) and MFA-Key-Reuse (MFA-KR). Existing variants for standard Multi-Head Attention (MHA), including SOTA methods like MLA, fail to maintain as strong performance under stringent Key-Value cache (KV cache) constraints.…

OpenCoder: The Open Cookbook for Top-Tier Code Large Language Models

ACL 2025long

Code LLMs have been widely used in various domains, including code generation, logical reasoning, and agent systems. However, open-access code LLMs mostly only release weights, lacking key features such as reproducible data pipelines and transparent training protocols, which are crucial for advancin…

Predictable Scale (Part II) --- Farseer: A Refined Scaling Law in LLMs

NeurIPS 2025spotlight

Training Large Language Models (LLMs) is prohibitively expensive, creating a critical scaling gap where insights from small-scale experiments often fail to transfer to resource-intensive production systems, thereby hindering efficient innovation. To bridge this, we introduce Farseer, a novel and ref…
