MOBA: Mixture of Block Attention for Long-Context LLMs

What changed

Researchers introduced Mixture of Block Attention (MoBA), applying Mixture of Experts principles to attention mechanisms to scale long-context LLM efficiency.

Why you should care

New attention mechanisms can reduce quadratic computational overhead in long-context models.
