*Frontend-oriented projects here refer to projects that focus on user chat interfaces, backend-oriented projects refer to projects that focus on API proxying and distribution, and one-stop solutions include both user chat interfaces and API proxying and management

We found that most AIGC commercial sites on the market are frontend-oriented lightweight deployment projects with beautiful UI interface designs, such as the commercial version of Next Chat. Due to its personal privatization-oriented design, there are some limitations in secondary commercial development, presenting some issues, such as:
- Difficult conversation synchronization, for example, requiring services like WebDav, high user learning costs, and difficulties in real-time cross-device synchronization.
- Insufficient billing, for example, only supporting elastic billing or only subscription-based, unable to meet the needs of different users.
- Inconvenient file parsing, for example, only supporting uploading images to an image hosting service first, then returning to the site to input the URL direct link in the input box, without built-in file parsing functionality.
- No support for conversation URL sharing, for example, only supporting conversation screenshot sharing, unable to support conversation URL sharing (or only supporting tools like ShareGPT, which cannot promote the site).
- Insufficient channel management, for example, the backend only supports OpenAI format channels, making it difficult to be compatible with other format channels. And only one channel can be filled in, unable to support multi-channel management.
- No API call support, for example, only supporting user interface calls, unable to support API proxying and management.
Another type is API distribution-oriented sites with powerful distribution systems, such as projects based on One API. Although these projects support powerful API proxying and management, they lack interface design and some C-end features, such as:
- Insufficient user interface, for example, only supporting API calls, without built-in user interface chat. User interface chat requires manually copying the key and going to other sites to use, which has a high learning cost for ordinary users.
- No subscription system, for example, only supporting elastic billing, lacking billing design for C-end users, unable to meet different user needs, and not user-friendly in terms of cost perception for users without a foundation.
- Insufficient C-end features, for example, only supporting API calls, not supporting conversation synchronization, conversation sharing, file parsing, and other functions.
- Insufficient load balancing, the open-source version does not support the weight parameter, unable to achieve balanced load distribution probability for channels at the same priority (New API also solves this pain point, with a more beautiful UI).
Therefore, we hope to combine the advantages of these two types of projects to create a project that has both a powerful API distribution system and a rich user interface design, thus meeting the needs of C-end users while developing B-end business, improving user experience, reducing user learning costs, and increasing user stickiness.
Thus, Chat Nio was born. We hope to create a project that has both a powerful API distribution system and a rich user interface design, becoming the next-generation open-source AIGC project's one-stop commercial solution.
