Application portal on the official website
An application portal and related code for "Cyber," a model for cybersecurity, were found in the code of the official website of Chinese AI company DeepSeek, China's IT Home and other outlets reported on Oct. 30. The screen describes "DeepSeek Flash Cyber" as a dedicated cybersecurity API, and it is reportedly in a limited testing phase visible only to some users. @LeroyLi311063, an X account that posts information from China, also reported on the model the same day.
The code contains two names: "cyber-personal-v3" for individuals and "cyber-enterprise-v4" for businesses. The individual version targets individual security professionals, while the business version targets corporations.
Dedicated key and strict identity checks
Using the model requires a dedicated "Cyber Key" rather than a regular API key. It is issued after an application is submitted and passes review, and the code also includes systems for issuing keys and managing usage.
Individuals submit identity card information and undergo facial recognition. Businesses submit real-name documents, a business license and a letter of authorization. Both must complete real-name verification and have no record of violations in the past 90 days. In addition, the account must be registered in mainland China and linked to a mainland China mobile phone number.
@LeroyLi311063 reported talk that the cyber capabilities would be removed from a version with publicly released weights, but this has not been confirmed in media reports.
Companies limit access to "approved users only"
Providing models with capabilities that can also be used for attacks only to vetted users is spreading across companies. Anthropic offers "Claude Mythos," a model for cyber defense, only to a limited number of organizations. xAI also appears to be preparing a category in the Grok API that permits offensive and defensive content only for approved keys (related article).
There are also rumors that DeepSeek will release a large model at the end of the year (related article). The company has disclosed nothing about Cyber's performance or release timing.
