New API Proposal - Q&A Assistant - Manage (from "MaaS" API family)

[lihaojie-CMCC]

Proposal to create a "Q&A Assistant - Manage" API:

This API enables developers to quickly construct unique Q&A Assistant applications based on various models and datasets provided by MaaS according to customer needs. The Q&A Assistant application fully leverages the intent understanding capabilities of LLMs. It combines a proprietary dataset to answer users' questions in natural language.

Based on the large model capabilities provided by the model provider integrated with the CSPs, it supports the construction of Q&A Assistant according to the needs of the developers.

This API offers services to developers who need to construct Q&A Assistants.
