Designing Domain LLMs for Telecom/Finance Workflows

Why Domain LLMs are Essential

Generic Large Language Models are highly capable but fail when confronted with industry-specific terminology. A telecom support agent needs to know what an 'HLR lookup failure' means, while a finance agent must comprehend tax law variations.

Curating the Training Corpora

The performance of a domain LLM depends entirely on data quality. We compile millions of tokens of sanitized logs, legal briefs, product manuals, and tax guidelines. We run strict cleaning filters to remove PII (Personally Identifiable Information) before training begins.

Supervised Fine-Tuning (SFT) & Direct Preference Optimization (DPO)

We initialize training on open base weights (Llama 3, Mistral) and perform task-specific fine-tuning. We then apply DPO using expert human feedback to align the model's tone and compliance boundaries with industry standards.

Enforcing Data Security and Compliance

Unlike public API endpoints, our domain models deploy inside secure, sandboxed client VPCs or on-premise GPU nodes. This ensures that no customer transaction logs or prompt histories leave the company perimeter, supporting compliance guidelines under India's DPDP Act of 2023.
