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.

Palantir’s Quiet Takeover of Media’s Data Stack

Palantir is expanding from government work into media and marketing, striking deals with Fox News Digital, Zeta Global, Stagwell, and USA Today Co. These partnerships involve building internal platforms, analyzing audience data, and integrating AI. Despite employee concerns at USA Today, executives praise Palantir's speed and ontology-based approach. The company embeds forward-deployed engineers and offers interoperability with various AI models. For Zeta and Stagwell, Palantir also serves as a sales channel, taking a revenue share. The push reflects a broader industry shift toward leveraging data for monetization and efficiency.

• Zeta Global signed a seven-year partnership with Palantir in June, rebuilding its data cloud on Foundry after skipping a competitive review.
