Why AI Users Are Raving About GLM 5.2
June 22, 2026
AI Summary
5 min readA resurfaced June quote from Senator Mark Warner claimed that Mythos had broken into almost all classified NSA systems in hours, not weeks, which many initially read as evidence of a real breach that justified the Fable 5 export controls.
The quote came from NSA Director Joshua Rudd via the Senate Intelligence Committee vice chair on June 11, the same day Amazon CEO Andy Jassy alerted the administration to the jailbreak. Reporter Shoshang Joshi later clarified that the line described controlled red-team tests rather than an actual external breach, and that caveats about Mythos operating with other tools under specific conditions had been omitted. Commentators such as Peter Wildeford outlined more plausible scenarios, including simulated exercises on replica systems, pre-provided architecture details, or tests limited to poorly secured internal networks. The CyberSec Guru confirmed the incident occurred inside an NSA-run adversarial exercise. President Trump, in a Saturday Axios interview, described Anthropic’s response as responsible, ruled out using the Defense Production Act, and stated that the good far outweighs the bad while emphasizing continued efforts to address remaining risks.

GLM 5.2 is looking like the first open-weight model in a while that might survive contact with real-world usage, especially for coding and web design. NLW looks at why builders are comparing it to the DeepSeek R1 moment, where the hype is justified, where the cost story is more complicated, and what it means for enterprise AI stacks that can no longer assume a simple OpenAI-versus-Anthropic race.
