An intelligent web service consultant has been created that uses OpenAI LLM models (GPT-4.1-mini) and the RAG approach (search + generation) to accurately and contextually answer user questions. Key benefits for business:

• High speed and accuracy of responses - due to fast searching of the internal knowledge base (via FAISS) and additional enrichment via LLM.
• Integration with external sources - an MCP agent has been implemented for automatic search of additional information on the internet if local data is insufficient.
• Flexible agent logic is built using LangGraph, allowing for easy adaptation of behavior to any Business processes.
• Observability and analytics via Langfuse — every step of the model's operation is tracked, providing transparency and quality control.
