1. ⚡ US Government Clears Anthropic Mythos 5 — Fable 5 Still Suspended
- Commerce Secretary Howard Lutnick signed a letter June 26 clearing Anthropic to restore Mythos 5 access for ~100–150 "trusted" US organizations via Project Glasswing (CNBC, TechCrunch)
- Named Glasswing members: Apple, Google, Cisco, NVIDIA, Microsoft, JPMorgan Chase, CrowdStrike, Palo Alto Networks, AWS, IBM — plus ~100 more Fortune 500 and critical-infrastructure operators
- Lutnick letter language: "appropriate safeguards are in place" — Glasswing's existing vetting is accepted as sufficient
- Fable 5 is explicitly excluded from the clearance and remains suspended; the public consumer tier stays offline (now day 18 of suspension)
- Sam Altman publicly criticized the opacity: the government "picking winners" in AI access
- Why it matters: The June 12 suspension + June 26 selective re-authorization is the first time the US government has exercised direct control over which organizations can access a specific frontier AI model. The Mythos 5 clearance follows the exact same day as GPT-5.6 Sol's government-gated preview (June 26) — on a single Friday, the US government effectively established a new "trusted-partner" tier for frontier AI above both the public market and the private API. This is a structural shift in AI governance, not just an Anthropic story.

Grok 5 misses June 30 Q2 deadline — xAI's 6T-parameter MoE flagship is still in training on Colossus 2 as of June 30. The Q2 window has now closed. Multiple sources confirm no release; July is the next target. Musk had previously claimed a 10% AGI probability for Grok 5. Monthly release cadence (Grok 4.5 → Grok 5) still the stated strategy.
