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

• High speed and accuracy of answers — due to fast search in the own knowledge base (via FAISS) and additional enrichment via LLM
• Integration with external sources — an MCP agent has been implemented to automatically search for additional information on the Internet if local data is insufficient.
• Flexible logic of the agent's operation is built using LangGraph, which makes it easy to adapt behavior to any business processes.
• Observability and analytics via Langfuse — every step of the model's operation is tracked, which provides transparency and quality control.
