- Agent performance in production is governed more by harness design and fault tolerance than by model scale, while current benchmarks systematically conflate the two. ⏱️ Chapters 00:00 Intro 00:16 AI's Real Bottleneck: The Scaffolding Around Models, Not Model Scale 00:20 Highlights 02:10 Agent reliability is a harness problem, not a model-scale problem 05:00 Scientific-agent benchmarks expose a validity and safety gap 08:15 Embodied AI's bottleneck is deployment robustness, not demo capability 11:04 Efficiency gains depend on system co-design, not compression alone 13:48 Alignment research…
