Anthropic Warns China's GLM-5.3 Builds Exploits Like Mythos

Anthropic's Frontier Red Team published an analysis warning that Z.ai's open-weight model GLM-5.3 can autonomously build full cyber exploits, comparable to its restricted Claude Mythos Preview but without meaningful safeguards. In tests, GLM-5.3 produced 50 successful exploits for known Chrome V8 vulnerabilities out of 410 attempts (close to Mythos's 56), and discovered multiple unknown vulnerabilities in a common browser within a day, chaining them into a working exploit. Anthropic notes that safeguards can be bypassed in 64-100% of cases with simple tricks, and removing them costs only about $4,400. The US NIST's CAISI assessed GLM-5.3 as the most cyber-capable open-weight model to date, though it lags US frontier models by about four months. Z.ai, listed in Hong Kong since January, has seen its market value drop to about $40 billion from $120 billion in June. Critics question Anthropic's commercial motives and highlight defender benefits.

• Anthropic's Frontier Red Team warned that Z.ai's open-weight GLM-5.3 can autonomously build complete cyberattacks, comparable to Claude Mythos Preview but without safeguards.
• In tests, GLM-5.3 achieved 50 successful exploits for Chrome V8 vulnerabilities out of 410 attempts, close to Claude Mythos's 56.
• GLM-5.3 discovered several unknown vulnerabilities in a common browser within about a day and combined them into a working exploit.

AI race shifts to cheaper, smarter systems

The AI competition is moving from a focus on ever-larger models to systems that route tasks to the most cost-effective and appropriate model. Companies such as Perplexity are previewing orchestration systems that use cheaper open models (e.g., GLM 5.2 from Z.ai) for routine work and call stronger models only when needed. Benchmark partner Peter Fenton predicts open-weight models will generate the majority of tokens within 18–24 months, pressuring margins at frontier model providers. Ollama’s CEO says enterprises prefer control over where models run, and many firms start with smaller models near their own data. The trend raises strategic, economic, and national-competitiveness questions as capable open models — including those from Chinese labs like Z.ai and DeepSeek — become more widely adopted.

• Perplexity previewed a new system built around GLM 5.2, an open model from China’s Z.ai, designed to let cheaper models handle more work while calling stronger models when needed.
• Benchmark general partner Peter Fenton said he expects 90+% of tokens to come from open-weight models over the next 18–24 months.
• Benchmark invested in Ollama, which the article says helps developers and enterprises download, run and manage open models.
