IndicVisionBench: Benchmarking Cultural and Multilingual Understanding in VLMs

Vision-language models (VLMs) have demonstrated impressive generalization across multimodal tasks, yet most evaluation benchmarks remain Western-centric, leaving open questions about their performance in culturally diverse and multilingual settings. To address this gap, we introduce IndicVisionBench, the first large-scale benchmark centered on the Indian subcontinent. Our final benchmark consists of a total of 5K images and 37K+ QA pairs across 13 culturally grounded topics. In addition, we release a paired parallel corpus of annotations across 10 Indic languages, creating a unique resource for analyzing cultural and linguistic biases in VLMs. We evaluate a broad spectrum of 8 models, from proprietary closed-source systems to open-weights medium and large-scale models. Our experiments reveal substantial performance gaps, underscoring the limitations of current VLMs in culturally diverse contexts. By centering cultural diversity and multilinguality, IndicVisionBench establishes a reproducible evaluation framework that paves the way for more inclusive multimodal research. Vision-language models (VLMs) (Bai et al., 2023; Chen et al., 2024; Lu et al., 2024; Wang et al., 2024b; Laurenc on et al., 2024; Tong et al., 2024; Xue et al., 2024) have demonstrated strong performance across a variety of multimodal tasks. However, existing benchmarks (Antol et al., 2015; Fu et al., 2023; Goyal et al., 2017) remain heavily Western-centric, limiting our understanding of how these models generalize to culturally diverse and multilingual settings. While some recent efforts partially cover this diversity (Romero et al., 2024; Nayak et al., 2024; V ayani et al., 2025), a systematic, large-scale benchmark capturing India-specific cultural concepts across multiple languages is still lacking. To address this gap, we introduce IndicVisionBench, a culturally grounded evaluation benchmark tailored for the Indian subcontinent. To the best of our knowledge, this is the first large-scale benchmark explicitly designed to assess VLMs in the context of Indian culture and languages. We use states as a proxy for cultural groups following prior works (Adilazuarda et al., 2024; Nayak et al., 2024).
