The filing cycle is 5-8 months, and this filing is not a one-time approval. The Cyberspace Administration usually receives 5-8 rounds of feedback in the normal process, and only after the model and materials are free of issues is the filing granted. The full name of the algorithm filing is "Internet Information Service Algorithm Filing," which is a mandatory filing system initiated by the Cyberspace Administration, in collaboration with the Ministry of Public Security, the Ministry of Industry and Information Technology, and the State Administration for Market Regulation. This system was implemented starting March 2022, aiming to regulate the recommendation of internet information service algorithms, and to counter unreasonable applications such as harmful deep synthetic generation, algorithm discrimination, "big data killing the old," and诱导沉迷. Without filing, you may face the risk of your website or APP being removed from the market and administrative penalties, and may also be unable to update products on the app market or release new products. The algorithm filing process is highly complex and time-consuming, typically completed within 3-4 months, but with the recent AI boom and increased regulatory measures by the state, it's mandatory for generative algorithms to be filed and registered. This may lead to extended review times due to the increasing number of filings and the lack of experience in submissions, as the reviewers may not always provide all issues for rectification, posing a risk of multiple rejections. Additionally, if you're using someone else's API algorithm for generative synthesis, you also need to file. In the filing identity, you should select "service provider" rather than "service technical supporter."
