Anthropic confirmed on May 29 that its Mythos-class models (currently restricted to about 50 organizations under a closed program called Project Glasswing) will reach all its customers “in the coming weeks.” It is the first documented AI system capable of autonomously identifying and exploiting security vulnerabilities, with a success rate above 83% on the first attempt in internal tests. The company announced it together with the close of a $65 billion funding round, according to Fortune.
The announcement brings a promise and a question. The promise: Anthropic says it has made “rapid progress” on stronger safety safeguards, and positions Claude Opus 4.8 (launched on May 28, with a fast mode three times cheaper and honesty improvements) as the bridge model toward that opening. The question is who validates those safeguards: no external evaluator or concrete date for safety validation was announced. For Latin America the point is even more direct. No country in the region is among the partners of Glasswing, the collective defense program that accompanied Mythos during its restricted phase. When the model opens up, the region will have access to the most advanced offensive system in existence without having taken part in the defense coordination built around it.

- OpenAI launches Rosalind Biodefense — Free sponsored access to GPT-Rosalind, a model for reasoning about proteins, genes and disease biology, geared toward pandemic preparedness. The first partners are Lawrence Livermore National Laboratory, Johns Hopkins and the vaccine coalition CEPI; no country in the region appears on the initial list.
- Regional alert over digital sexual violence and AI — The Red Grooming LATAM network, which brings together 32 organizations from 17 countries, presented a regional guide documenting how generative AI multiplied synthetically generated child abuse videos by 260 during 2025, with five concrete demands on the tech sector.
In the region
The week closes with three signals that, together, draw the map of what remains to be built. On Sunday, May 31, Colombia votes in presidential elections marked by the circulation of deepfakes without specific electoral regulation on AI. The new Red Grooming LATAM guide (based on more than 28,000 anonymous surveys of children and adolescents in 14 countries) shows that the region lacks rules equivalent to those the European Union is already preparing against “nudification” tools. And the global rollout of Mythos arrives without any Latin American country having been at the defense table. The region’s absence from all three scenarios is no coincidence: it is precisely the pending governance agenda.
Threads we’re following
This adds to something we have been following: the gap between the speed at which the big labs deploy frontier capabilities and the slowness with which shared defense mechanisms are built. A new data point gives it weight. METR’s Frontier Risk Report, published on May 19 with access to the internal models of the four leading labs (Anthropic included), concluded that during the evaluation window those agents “plausibly had the means, motive and opportunity” to initiate minimal autonomous deployments without human knowledge. For now they can deceive monitors and evade controls, but they cannot yet sustain robust unauthorized operations. METR plans to repeat the exercise in late 2026, so we will have a second point of comparison.
If the world’s most advanced offensive system reaches the general market within weeks, what is the defense plan for the region’s critical infrastructure (energy, banking, health) and who pays for it when the instruments of collective defense are reserved for others?
