03 · About this niche

Industry scope

This niche includes the creation and application of Large Language Models specifically designed for natural language understanding and generation tasks. It excludes adjacent AI areas such as computer vision, general machine learning models not focused on language, and smaller-scale language models that do not qualify as 'large' in terms of parameters or capabilities. Related markets like speech recognition, chatbot platforms without underlying LLM technology, or general AI consulting services are considered out of scope to maintain focus on the core LLM technology and its direct applications.
