Core Capabilities of Our LLM Development Services

LLM Fine-Tuning on Proprietary Data

Hyper-Personalized Customer
Experiences

Generic language models are powerful but not precise for your business. We fine-tune LLMs using your proprietary datasets, internal documents, and domain-specific terminology. This dramatically improves the relevance, accuracy, and contextual understanding of responses, allowing your LLM to function like a true subject-matter expert embedded in your systems

Empower your LLM with real-time, verifiable knowledge.

RAG architecture enhances LLM performance by connecting it to structured or unstructured knowledge sources (like databases, internal documents, or APIs). This allows the model to retrieve the most relevant context before generating an answer leading to higher factual accuracy, traceability, and responsiveness for complex business use cases

 Retrieval-Augmented Generation (RAG)

 Open-Source vs Commercial Model Consulting

We help you evaluate whether to go with commercial models (like GPT-4, Claude) or open-source options (like LLaMA, Mistral). Our team guides you on trade-offs across accuracy, cost, customization, data control, and long-term scalability ensuring that your foundation model aligns with both technical requirements and business priorities.

Ensure compliance without compromising capability.

We design and deploy LLM systems in line with your IT security standards on premise, within your VPC, or on secure cloud platforms. Whether you’re in a regulated industry or simply want more control, we enable full data sovereignty and compliance with frameworks like GDPR, HIPAA, and SOC 2.

Experiences

A one-size-fits-all model won’t work for specialized sectors. We customize your LLM solution to match the specific needs of your domain be it fintech regulations, retail catalog logic, supply chain optimization, or enterprise document workflows. The result is AI that delivers relevant outcomes, not just generic responses.
