Many Dialects, Many Languages, One Cultural Lens: Evaluating Multilingual VLMs for Bengali Culture Understanding Across Historically Linked Languages and Regional Dialects

BanglaVerse is a new benchmark that evaluates multilingual vision‑language models on Bengali culture, covering nine visual domains and expanding to four languages and five Bangla dialects for a total of about 32,200 artifacts. It includes visual question answering and captioning tasks built from 1,152 manually curated images. Experiments show that models perform worse on dialectal variants and that missing cultural knowledge, rather than visual grounding, is the main bottleneck.

Which India Survives Translation? Narrative Homogenisation Across Indian Oral Traditions in LLMs

The study investigates how large language models (LLMs) handle diverse Indian oral traditions, using the Rajasthani Pabuji epic, Tamil Sangam poetry, and Bengali folk tales as case studies. By prompting Claude Sonnet and Gemini with 54 generation requests across generic, culturally specific, and regional-language prompts, the authors measured reference drift and cross-tradition convergence using Sentence‑BERT embeddings. Results show that while outputs stay closer to their own tradition than to others, there is significant cross‑tradition similarity (0.52–0.66), indicating partial homogenisation; moreover, regional‑language prompting consistently reduced fidelity to authentic traditions.

Order Matters: A Chinese Multi-Panel Meme Benchmark for Vision-Language Reasoning

The paper introduces CMPM, a Chinese Multi-Panel Meme benchmark comprising 1,214 annotated samples that capture five structural types, ordering dependencies, panel-order constraints, and optional comment context. It defines a two-layer evaluation: Task 1 tests structure typing and order-sensitive panel sequencing, while Task 2 assesses Chinese meme explanation generation using human ratings across visual, panel, humor, context, and faithfulness dimensions. Benchmarking five large vision‑language models shows that accuracy on canonical displays does not guarantee order understanding, as performance drops sharply under shuffled conditions, and that Gemini 3.1 Pro and GPT‑5.5 outperform open models in Task 2, with comment context providing only modest gains.
