Recently, Nemo Yang, a Chinese post-00s entrepreneur, founded the AI startup Kinesys AI, which launched the large-scale model middleware Cortex. Cortex has attracted angel investments from Zoom-affiliated, Getty family, and Kuaishou-related entities. It enables rapid integration of large-scale model APIs and access to data interfaces, significantly reducing the time cost for AI developers. With the surge in popularity of ChatGPT, large-scale model middleware has become a new investment hotspot. Companies like LangChain and LlamaIndex have also secured seed-round funding from renowned Silicon Valley investment institutions. Due to its high technical barriers, the large-scale model middleware sector is a niche industry with little competition, making it the current hot spot. Industry insiders believe that the market for large-scale model middleware is vast, capable of facilitating the implementation of AI applications, and holds promising prospects.
