On 19 August 2025, a new batch of standards in the telecoms industry YD/T 4392 series was released. Two relate directly to artificial intelligence: “General Capability Requirements for Artificial Intelligence Development Platforms - Part 2: Security Requirements” and “Part 4: Large Model Development and Application”, both effective on 1 December 2025.
The standards regulate the platform, not the model
The YD/T 4392 series is positioned as general capability requirements for AI development platforms. It differs from the better-known security standards for generative AI services: the latter constrain the final service, while the former constrain the platform that hosts model development, training and deployment.
The distinction has practical weight. Many companies do not offer generative services directly; they provide training frameworks, model repositories and computing scheduling. Such actors were previously covered by few dedicated standards, and now have corresponding industry norms.
Why security requirements warrant a dedicated part
Devoting Part 2 to “security requirements” shows that the drafters consider platform-layer risk to need separate treatment. A platform hosts large numbers of models and datasets, and once its security boundary fails, the impact spreads along the supply chain.
Platform security typically covers several dimensions: isolation and access control for model and data assets, traceability of the training process, and the platform’s own supply-chain security.
Relationship to the national standards system
AI national standards released in the same and later periods complete the rule set from different angles. See the cluster of AI national standards and the basic security requirements for generative AI services.
Industry standards are usually closer to concrete technical scenarios than national standards, land faster and are more readily cited in procurement and tender documents. See the national standards on agent interconnection.
Where platform companies can start
First, map your platform’s security capabilities against the standard, especially isolation, access control and audit trails.
Second, build the standard’s requirements into capability commitments to downstream customers as a point of differentiation.
Third, watch the implementation date. After 1 December 2025 the standard may be incorporated into contracts and technical assessments.
The value of a standard is that it turns “what a platform should do” from a matter of experience into a checklist that can be checked against. For AI platforms serving enterprise customers, that checklist will gradually become part of the entry threshold. See the national standards on AI operator interfaces.
