Final Summary & Recommendations

• This is the most significant 30-day AI launch window in history — do not sit it out

• Prioritize: Update Apple devices for Siri AI; test Gemini 3.5 Flash via API for your existing tools

• Watch: Claude Fable 5 / Mythos 5 re-release — when available, this should be your primary long-form AI workhorse

• Invest (if budgeted): Snap Specs is an early-mover opportunity for spatial and AR-native content creators

• Stay grounded: Not all announced features are live — verify availability before building workflows around any launch

"June 2026 is already being called the most concentrated AI model launch month in the industry's history."
