Artificial intelligence (AI) is a key to strategic operational efficiency and competitiveness for enterprises. In this context, Grok, developed by xAI, has rapidly attracted attention in the enterprise solutions space as a large language model (LLM) equipped with real-time data processing and advanced reasoning capabilities.

Generative AI has become a core driver of operational efficiency and innovation in enterprises. Among these models, Claude — the large language model (LLM) developed by Anthropic — has attracted attention for prioritizing safety and human-centered design. Its unique approach, Constitutional AI, aims to produce ethically guided and more transparent responses.

With advances in large language models (LLMs), the scope of generative AI use in enterprises and research institutions has expanded more than ever. However, simply using an LLM as-is is often insufficient to meet real-world business requirements. For example, when you want to incorporate the latest information or need responses grounded in internal knowledge, an LLM alone cannot handle it. In addition, for long-text processing and complex context understanding, gaps in knowledge and hallucinations (hallucination) become issues.

With the advancement of DX, generative AI is now widely used in text creation, customer support, and data analysis, contributing to improved efficiency and competitiveness. However, at the same time, a serious issue known as “hallucination” has emerged—when AI generates information that appears plausible but is in fact incorrect.

Natural Language Understanding (NLU), a core technology within Natural Language Processing (NLP), is an AI capability that accurately interprets context and intent from text and speech. Unlike simple word processing, NLU serves as the foundation for conversational AI, powering applications such as chatbots, voice assistants, and sentiment analysis. In business, NLU contributes to productivity gains and cost reduction by automating customer interactions and streamlining data analysis.
