On 11 September 2025 the Cyberspace Administration of China published the 13th batch of domestic deep synthesis service algorithm filings. The notice, issued under the Provisions on the Administration of Deep Synthesis of Internet Information Services, directs relevant service providers and technical supporters to check filing status through the algorithm filing system and to perform filing, amendment and deregistration duties as required.
What batching means
From the first batch to the thirteenth, the cadence of deep synthesis algorithm filing has stabilised. Batching is not merely a matter of publication frequency; it is a signal of institutional maturity: filing has moved from early concentrated filings onto routine rails.
For companies, batching brings two kinds of certainty. First, timing is more predictable — filing is not an occasional window but continuous intake with periodic publication. Second, the boundary of responsibility is clearer — deep synthesis service providers with public-opinion attributes or social mobilisation capacity, and those providing technical support to them, are both within scope.
Filing is not a one-off
A common mistake is to treat filing as a pre-launch formality. Under the regime, filing is a continuing duty:
Where services are added or functions change in a way that affects filing information, an amendment must be filed; where a service terminates, deregistration must be filed; technical supporters perform corresponding duties by reference. See our note on the deep synthesis filing process.
Filing also pairs with content labelling and security assessment: filing answers whether a service is on the register, labelling answers whether content is identifiable, and assessment answers whether risk is controllable. See our note on labelling enforcement.
Four questions for self-check
First, register status: are all deep synthesis services filed, with no missed related modules?
Second, information consistency: does filing information match actual product functions, and does iteration trigger an amendment?
Third, technical supporter role: if you provide deep synthesis technology to others, have you performed duties by reference? See our algorithm filing service.
Fourth, record completeness: are filing materials, amendment records and deregistration materials fully archived for later verification?
Routine filing requires companies to embed compliance into product iteration rather than rely on a single sprint.
