6G Open Radio Access Networks (ORAN) promises to open data interfaces to enable plug-and-play service Apps, many of which are consumer and business-facing. Opening up 6G access lowers the barrier to innovation but raises the challenge that the required communication specifications are not fully known to all service designers. As such, business innovators must either be familiar with 6G standards or consult with experts. Enabling consistent, unbiased, rapid, and low-cost requirement assessment and specification generation is crucial to the ORAN innovation ecosystem. Here, we discuss our initiative to bridge service specification generation gaps between network service providers and business innovators. We first review the state-of-the-art and motivation in 6G plug-and-play services and capabilities, potential use cases, and relevant advances in Large Language Models (LLMs). We identify an ample innovation space for hybrid use cases that may require diverse and variational wireless functionalities across its operating time. We show that the network specification can be automated and present the first automatic retrieval-augmented specification generation (RAG) framework for 6G use cases. To enable public acceptance and feedback, a website interface is also published for the research and industrial community to experiment with the RAG framework. We hope this review highlights the need and the emerging foundation models that advance this area and motivate researchers to engage with the framework.
