Anthropic launched Claude Fable 5 as its most powerful model yet, specifically touting its biology capabilities. However, users found the model refuses to answer basic high-school-level biology questions, instead handing queries off to the previous flagship model. The contradiction raises questions about overly aggressive safety filters undermining the model's advertised strengths.
This essay explains why most cells remain small through two physical limits: surface-area-to-volume ratio and diffusion. As cells grow, volume rises faster than membrane area, making nutrient intake, waste removal, and energy support harder. Larger cells also slow molecular encounters, though examples like red blood cells, oocytes, organelles, and giant bacteria show how biology works around these constraints.
