OTel-LLM-12B-Safety

OTel-LLM-12B-Safety is a telecom-specialized language model fine-tuned on telecommunications domain data. It is part of the OTel Family of Models, an open-source initiative to build industry-standard AI models for the global telecommunications sector.

Model Details

Attribute	Value
Base Model	google/gemma-3-12b-it
Parameters	12B
Training Method	Full parameter fine-tuning
Language	English
License	Apache 2.0

Training Data

The model was trained on high-quality telecom-focused data curated by 100+ domain experts from organizations including AT&T, Microsoft, AMD, GSMA, RelationalAI, Essential AI, Purdue University, Khalifa University, University of Leeds, Yale University, The University of Texas at Dallas, NetoAI, and MantisNLP.

Data Sources:

• GSMA Permanent Reference Documents
• 3GPP Specifications
• O-RAN Documentation
• RFC Series
• eSIM, terminals, security, networks, roaming, APIs
• Industry whitepapers and telecom academic papers

Intended Use

The OTel model family is designed to power end-to-end Retrieval-Augmented Generation (RAG) pipelines for telecommunications. The three model types serve complementary roles:

1. Embedding — Retrieve relevant chunks from telecom specifications, standards, and documentation.
2. Reranker — Re-score and prioritize the retrieved chunks for relevance.
3. LLM — Generate accurate responses grounded in the retrieved context.

Users can deploy the full pipeline or use individual models independently based on their needs.

Note: The LLMs include abstention training — if the model does not receive sufficient context, it will decline to answer rather than hallucinate. This means the models are optimized for context-grounded generation, not open-ended question answering.
