Chinese AI company Zhipu claims its new is a better bug-finder than Anthropic, OpenAI

ASIA IN BRIEF Chinese company Zhipu last week launched a new AI model called GLM-5.3 that it claims has bug-finding powers that match those possessed by American models.

The company’s announcement includes benchmark data that finds GLM-5.3 beats Fable 5 and GPT-5.6 Sol on the CyberGym benchmark, a test of a model’s ability to solve real-world cybersecurity challenges.

“As we scaled post-training, cyber capability developed faster than we expected.

GLM-5.3 is state of the art on CyberGym for vulnerability discovery, and its gains are largest further up the exploitation chain,” the company wrote, adding that the model “did not simply become better at identifying isolated flaws: it began to reason across multiple stages of exploitation, forming coherent plans for complete exploitation chains.” The company said it has worked with Chinese companies to test the model on real-world codebases, and found 2,436 vulnerabilities across 269 projects, including 1,097 medium-to-high severity issues.

The findings span system kernels, operating systems, browser engines, open-source infrastructure, web applications, and network protocols.

“Many had remained unnoticed for years or even decades, with the oldest dating back roughly 40 years,” the announcement states.

GLM-5.3 also performed worse than western models on other security and coding benchmarks.

Yet the fact that the model is a highly-capable bug finder signals that China is not far behind in terms of being able to poke holes in its rivals software and developed that capability very quickly after the debut of Anthropic’s Mythos.

Any advantage the US felt it had as the home of Anthropic has therefore dissipated.

Korea signals legal action against Apple, Google app store strangleholds South Korea’s Communications Commission last week found Google and Apple had abused their app store monopolies, and promised stern sanctions will follow.

In 2021, South Korea passed world-first legislation requiring app store operators to offer the option to use third-party payment schemes.

Apple and Google did so, but charged a 26 percent transaction fee for doing so – meaning they earned almost as much revenue when users chose third-party payment providers as they did from their own schemes.

The regulator has previously warned that it will impose the highest possible penalty available under law, which is three percent of revenue earned by non-compliant behaviour.

That’s probably back-of-the-sofa money for Apple and Google.
