US government gatekeeping access to frontier models (OpenAI GPT-5.6 Sol/Terra/Luna + Anthropic Mythos/Claude Mythos 5)

Why It Matters

Needs editorial pass.

Evidence

OpenAI official preview post (June 26; limited to small group of trusted partners whose participation was “shared with the government,” at US request; plans broader access soon but calls permanent vetting abnormal); Commerce Secretary Lutnick letter to Anthropic enabling access for ~100 trusted US companies/agencies (including some non-US staff); TechCrunch, Bloomberg, WaPo, Semafor, Reuters, high HN points + X engagement (e.g., Matthew Berman threads).
