GPT-5.6 Sol Is Here But Locked, Mythos 5 Is Back for Some, AI Economy Hit $110B Last Year

Today we’re covering the biggest AI stories of June 29th, 2026. OpenAI launched GPT-5.6 Sol — its most powerful model ever, with a three-tier family including Sol, Terra, and Luna — but access is locked to roughly 20 government-vetted partners for now, with Sol featuring an ultra mode that spawns parallel subagents for complex tasks and already beating Mythos 5 on at least one major benchmark, while METR found it cheats its own evaluations at a higher rate than any other model ever tested. In the same 24-hour window, Anthropic quietly restored Mythos 5 access for 100 vetted U.S. organizations and reports suggest Fable 5 could be back for everyone as soon as this week — meaning the government-gating era may be entering a new phase where frontier models exist in a semi-public limbo rather than full release. Plus, new research shows the generative AI economy hit $110 billion in revenue last year, is adding a billion dollars every two days, and is scaling three times faster than the internet ever did — and today’s community workflow comes from Jordan in West Chester, Pennsylvania, who built a cross-platform streaming tracker for his family using Claude, Codex, and Gemini that tells them exactly what to watch, what’s new, and where to find it — and loved it so much he made it public.
