Anthropic has announced the rollout of its new large-language model, Mythos, alongside a high-profile visit to South Korea by NVIDIA CEO Jensen Huang.
These developments signal a rapid acceleration in AI capabilities and hardware integration. The ability of new models to identify software vulnerabilities is prompting national governments to overhaul their cybersecurity defenses.
Anthropic announced on May 28, 2026, that it would release the Mythos model to all customers in the coming weeks [1]. At the same time, the company launched an upgraded Claude Opus 4.8 model [1]. A spokesperson for Anthropic said the company is launching the upgraded model while working to release the market-moving Mythos model.
While some reports suggest the model is already being delivered with safety measures, other sources indicate a phased rollout [1]. The power of the new technology has already drawn attention from government officials. On May 12, 2026, the South Korean Ministry of Science and ICT said the country is preparing new measures to counter AI-powered cyberattacks [2]. This decision followed a preview of Claude Mythos that demonstrated an advanced ability to find and exploit software vulnerabilities [2].
Further discussions regarding AI trust, and safety took place during a conference in South Korea on May 26, 2026 [3]. These talks coincided with the visit of Jensen Huang, who traveled to the region to showcase NVIDIA's AI hardware and software ecosystem to policymakers and partners [4].
Analysts note that the intersection of advanced software like Mythos and NVIDIA's hardware infrastructure creates a potent combination for industrial AI application. However, the speed of these releases continues to challenge the pace of regulatory oversight. The South Korean government's rapid response to the Mythos preview highlights the growing tension between AI innovation and national security [2].
“South Korea is preparing new measures to counter AI‑powered cyberattacks”
The simultaneous release of a highly capable model like Mythos and NVIDIA's strategic push into South Korea underscores a shift toward 'AI sovereignty.' As models become capable of autonomous vulnerability research, nations are moving beyond general regulation toward specific, defensive cybersecurity frameworks to protect critical infrastructure from AI-driven threats.
