Our Large Language Model Development Services
Belitsoft offers a suite of LLM development services to meet your industry-specific needs and align with your domain requirements
Large Language Model Development
As a customized solution, depending on your request, we can build your LLM from scratch, starting from the ground up, or fine-tune, scale and optimize existing pre-trained models. Belitsoft builds, trains, and deploys custom LLMs using deep learning frameworks like PyTorch, TensorFlow, etc.
We can strictly limit your LLM to rely entirely or as much as possible on your private data rather than general knowledge to reduce hallucinations and make answers maximally accurate and relevant. This is not always possible with generic LLMs like ChatGPT, as they have limitations.
Large Language Model Integration
Belitsoft integrates your LLMs with your core business applications and bridges your LLM with existing internal and external systems for access to real-time data, including enterprise systems (CRM, ERP, content management platforms, speech recognition platforms, etc.), backends, rule-based systems, database servers, API services (OpenAI API), agent frameworks, and function-calling tools. We also integrate LLMs with event-driven systems, cloud services, and document repositories, as well as implement retrieval-augmented generation (RAG). After full automation, your LLM will read and write data, format it into reports or dashboards, fill forms, and much more.

Large Language Models Use Cases

Large Language Models for Healthcare
Custom LLM use cases in healthcare include using LLM-based extensions to traditional applications already used in health systems, such as healthcare business intelligence, healthcare document management, clinical decision support, and customer support tools. Such extensions provide greater benefits than traditional systems alone and cannot be built on generic systems like ChatGPT due to the requirement for deep domain expertise, security considerations, and long-term business vision (as they sell enterprise-wide products rather than just test hypotheses).
