Nemo Yang, a post-00s Chinese entrepreneur, founded Kinesys AI and launched the large model middleware Cortex, which has attracted considerable interest from investors. Cortex enables quick integration of large model APIs and data interface access, saving AI developers a significant amount of time. Startups in the large model middleware space, such as LangChain and LlamaIndex, have also secured investments from Silicon Valley firms. Due to the high technical barriers, competition in the large model middleware field is not intense, making it a promising niche industry. The market for large model middleware is vast and is expected to facilitate the deployment of AI applications.
