OTel: Open Telco AI Datasets, Benchmarks, and Models
This study addresses the absence of unified, open artificial intelligence resources in the telecommunications domain by proposing OTel, an open-source framework. By integrating multi-source data and evaluation partitions, this work constructs high-quality datasets encompassing tasks such as retrieval and reranking. Furthermore, it establishes a reproducible baseline for telecommunications AI development through full-parameter post-training, embedding models, and context-grounded large language models (LLMs). The project releases thirty post-trained models to facilitate community-driven extension. Experimental results demonstrate strong performance, achieving an NDCG@10 of 93.1% for retrieval, an MRR@10 of 0.947 for reranking, and an LLM accuracy of 87.8%. With cumulative downloads exceeding sixteen million, OTel provides a standardized and open foundation for advancing telecommunications AI research.
