Why do you need corporate LLMs?

.what we do

The most effective way to start is with a Corporate LLM is to build a centralized AI system tailored to your company’s data, language, and goals. ​

Even without fine-tuning and historical data, you can deliver immediate, relevant results through prompt-based customization using top foundation models like OpenAI’s GPT-4, Google’s Gemini, or open-source alternatives like Mistral. This unlocks high-ROI automation with minimal effort. ​

Tools like AI email auto-response systems can instantly reply to incoming leads with personalized, up-to-date information. AI chatbots provide 24/7 support, while virtual avatars guide users through complex workflows. These AI agents can operate independently, reduce manual effort, and create real business value.​

LLM MODELS WE
IMPLEMENT BY ​
CUSTOMIZATION
APPROACH​

PUBLIC NON-CUSTOMIZED MODELS​

Pre-trained models provided by third-party services and accessible via APIs over the internet. These are general-purpose models that cannot be customized with user-specific data.

  • ChatGPT or OpenAI API​
  • Google Gemini​
  • GitHub Copilot

CUSTOMIZED AI MODELS AS A SERVICE​

Pre-trained models that can be customized with user-specific data to better meet individual needs. They are hosted and managed by third-party providers but allow for some degree of customization.

  • OpenAI API (customized)​
  • Azure OpenAI Service​
  • Google Gemini

PRIVATELY
HOSTED ​AI MODELS

AI models deployed on an organization’s own infrastructure, whether on-premises or in a private cloud. This ensures complete control over the data and the environment in which the models operate.

  • Llama 3 (Meta)​
  • Mistral 7BGPT-J​
  • GPT-NeoXPhi-2​
  • NVIDIA NeMo

Leora: AI-Powered Voice Sales Assistant

This project showed that AI shouldn’t be used just for its own sake — it needs to solve real business problems. We created Leora to address specific challenges in our sales process, and by using the RAG approach, we ensured the assistant gave accurate, domain-specific answers instead of generic ones. The rapid prototyping allowed us to validate the concept within days and then focus on refining the user experience.
