arXiv:2606.14747v1 Announce Type: cross Abstract: Recent advancements have significantly expanded the theoretical context windows of Multimodal Embedding Models (MEMs). However, larger context windows do not necessarily translate into effective comprehension and representation of long-context multimodal inputs, which remains a critical bottleneck for real-world deployment. To address the lack of systematic evaluation in this setting, we introduce MMLongEmbed, the first comprehensive benchmark for evaluating MEMs in long-context scenarios. MMLongEmbed comprises four retrieval tasks spanning mul
The rapid expansion of theoretical context windows in Multimodal Embedding Models (MEMs) necessitates systematic evaluation, making this benchmark timely for understanding practical limitations and capabilities.
Improved long-context understanding in MEMs is critical for real-world AI applications, moving beyond theoretical advancements to functional utility and deployment efficiency.
The introduction of MMLongEmbed provides a standardized framework for assessing how effectively MEMs actually 'understand' lengthy multimodal inputs, filling a critical gap in development and application.
