September is about to get crazy for AI This week: basically nothing. Next week: potentially multiple frontier models at once. Rumors are pointing to: • Claude Fable 5.2 • Claude Opus 5.2 • Gemini 4 Pro • Grok 4.7 • GPT-6 Sol • Kimi K3.1 Some of these could slip into October But if even half of these rumors are real… The AI leaderboard is about to get reset again.
