arXiv:2605.26935v1 Announce Type: new Abstract: Large language models have achieved strong performance across many NLP tasks, yet Urdu remains comparatively underexplored due to limited resources and fragmented evaluation settings. To address this gap, we introduce DunbaaBERT, a family of Urdu RoBERTa-base models trained from scratch with Byte-BPE vocabularies of 32k, 52k, and 96k tokens on a deduplicated 17GB Urdu corpus. We evaluate DunbaaBERT across intrinsic and downstream Urdu NLP benchmarks covering linguistic acceptability, news classification, offensive language detection, and sentimen
The proliferation of Large Language Models has exposed the disparity in resource availability and evaluation for various languages, particularly those outside major research hubs.
This development indicates a global movement towards language-specific AI models, potentially reducing dependency on models trained primarily on Western datasets and benefiting underserved linguistic communities.
The availability of open-source, Urdu-specific RoBERTa models will accelerate AI development and application in Urdu-speaking regions, fostering greater linguistic inclusivity in AI.
- · Urdu-speaking researchers and developers
- · Pakistan's technology sector
- · Linguistic minorities in AI
- · Monopolistic providers of general-purpose LLMs
- · English-centric AI frameworks
DunbaaBERT directly provides a foundational model for Urdu NLP tasks, enhancing accuracy and accessibility.
This could lead to a wave of new AI applications and services tailored for the Urdu language market, creating economic opportunities.
The success of such efforts might inspire similar 'localization' initiatives for other under-resourced languages, decentralizing AI development and fostering digital sovereignty.
