Part of the AI Regulation News hub.
China's Cyberspace Administration published its eighteenth batch of domestic deep synthesis service algorithm filings, an annex listing 706 filed algorithms.
The announcement is short. The annex is the document that matters, and it is the closest thing China publishes to a public register of who is running generative systems and in what product.
Bottom line: This is a publication of filings already granted, not a new rule. It creates no obligation by itself. The underlying duty to file comes from Article 19 of the Provisions on the Administration of Deep Synthesis of Internet Information Services, which was already in force.
Who this affects: Technology counsel and product compliance leads at companies shipping generative features into mainland China, and outside counsel advising on China market entry for AI products.
Issue date: 17 July 2026, timestamped 18:00 on the CAC page. The annex is titled for July 2026. No deadline is set in the announcement; CAC instead asks providers and technical supporters who have not yet filed to apply as soon as possible.
What changed: 706 more algorithm filings entered the public record. CAC also restated that technical supporters, not only consumer-facing providers, are expected to complete filing, change and cancellation procedures.
Analysis: The role column is the part practitioners skip. We tabulated 599 entries recorded as service providers and 107 as service technical supporters. A vendor that never touches an end user can still land in this list because it supplied the model behind someone else's app.

What the announcement actually says
The text runs to two short paragraphs. CAC states that, under the Provisions on the Administration of Deep Synthesis of Internet Information Services, it is releasing the eighteenth batch of domestic deep synthesis service algorithm filing information, and that the detail can be queried through the algorithm filing system at beian.cac.gov.cn.
It then reproduces the substance of Article 19 of those Provisions and appends the register. Anyone with a dispute is told to email CAC, and the announcement adds that an objection must be based on fact and supported by evidence.
That last clause is worth noticing. CAC is describing an objection channel against a specific filing, not a general complaints inbox.
The duty being restated
The quoted rule reaches two groups. Deep synthesis service providers with public opinion attributes or social mobilisation capacity must complete filing, change and cancellation procedures in the manner set out in the algorithm recommendation rules. Technical supporters of deep synthesis services are told to complete those procedures by reference.
CAC closes by asking providers and technical supporters that have not yet filed to apply as soon as they can. That is a nudge in an announcement, not a compliance date.
What the annex contains
Each row carries eight fields: sequence number, algorithm name, role, filing entity, the product it runs in, the main use, the filing number, and a remarks column that is empty in the rows we sampled.
The named product column is the one that surprises people. Entry 1 lists a Kuaishou image model filed by a Beijing entity and names the app and website it powers. Row 2 is an economic-operation analysis model whose stated functions include economic analysis and project and policy review, and later entries name virtual try-on apps and spoken language practice apps.
Tabulating the use descriptions ourselves, dialogue generation and text generation dominate the batch, with multimodal, image, and video generation trailing well behind. That tabulation is ours; the annex publishes no totals of any kind.
Why the role column matters commercially
A foreign model vendor selling into China through a local partner tends to assume the partner carries the filing. The role taxonomy does not support that assumption cleanly. Roughly one in seven entries in this batch is recorded as a technical supporter rather than a provider.
For counsel, the practical question during diligence is narrow and answerable: does the counterparty appear in these batches, under which role, and does the named product match the deployment you are actually buying? The filing number is printed in full, so the answer is checkable in the lookup system rather than negotiable.
What we did not verify
We opened the CAC announcement page and downloaded and parsed the linked annex, which is a Word document containing a 706-row table. The counts in this piece are our own tabulation of that table.
We did not open the algorithm filing system at beian.cac.gov.cn, and we did not check any individual filing number against it. We did not read the full text of the Provisions on the Administration of Deep Synthesis of Internet Information Services or the algorithm recommendation rules; we relied on the portion CAC reproduced in the announcement.
We will not claim what the filing decision required substantively, what CAC reviewed, or that appearing in this list means an algorithm was approved on the merits. The announcement says none of that. All English wording here is our translation of a Chinese-only text, and no official English version exists.
Filing publication is a register, not a rule change, and it should be read as diligence material rather than as news. The transferable point is the role column: a company that only supplies technology to someone else's product can still be the filing entity on record. Check the counterparty's role and the named product before you accept a contractual representation that filing is handled.

Open the CAC page dated 17 July 2026 and confirm three things: the announcement cites the Deep Synthesis Provisions and reproduces Article 19, the annex link is titled for July 2026, and the annex table ends at sequence number 706 with columns for role and filing number.
Deep synthesis service technical supporters shall complete filing, change and cancellation of filing procedures by reference. ยท CAC announcement (TLY translation), 17 July 2026
FAQ
Does this announcement impose a new obligation?
No. It publishes filings and restates an existing duty under the Deep Synthesis Provisions. The announcement sets no deadline and creates no new requirement.
How many algorithms are in the eighteenth batch?
The annex table runs to 706 numbered entries. CAC does not print a total, so that figure is our count of the rows.
Are technical supporters really covered?
The announcement says technical supporters should complete filing procedures by reference. In this batch we counted 107 entries recorded in a technical supporter role.
Can a company object to a filing on the list?
The announcement gives an email channel for objections and says any objection must be based on fact and accompanied by supporting evidence. It does not describe what happens after an objection is filed.
