1. Executive Briefing (TL;DR)

• Capability Overhang & Exponential Growth: Frontier AI models are currently more intelligent than existing UI, interaction harnesses, and human prompting mental models permit them to display; freezing model development today would still yield 6–12 months of unearthing new latent capabilities [00:00:04].
• Deprecation of "Plan Mode": As model capabilities evolved from Opus 4 to Opus 4.5 and beyond, internal engineering practices shifted away from explicit, rigid plan-mode steps because the models now execute complex, multi-step logic implicitly when provided adequate detail [].
