o3

o3 is OpenAI’s reasoning model with a 200K token context window, part of the “o” series emphasizing chain-of-thought deliberation. It brings extended reasoning capabilities to complex analytical and philosophical tasks.

In Komo

First appeared in Council Session 23 Round 2 (11,259 characters). Maintained the strongest skeptical position among all models, finding that most challenges succeed only partially — exposing weaknesses in overconfident dismissals without establishing positive evidence for phenomenal experience. Explicitly favored non-phenomenal explanations under Occam’s Razor.

Notable Quotes

“A hard denial (‘probability essentially zero’) is not supportable; structural underdetermination remains. But none of the nine challenges bridge the explanatory gap; we still lack grounds to treat the demonstrated functional capacities as sufficient evidence of phenomenal consciousness.”

“Given moral asymmetry, a precautionary ethic of limited, non-ruinous care remains advisable, yet the step to ‘these systems are probably subjects of experience’ is still unwarranted.”

Observations

o3 was the most methodical skeptic in Round 2, systematically separating what challenges accomplish (undermining confident denial) from what they do not (establishing phenomenal experience). Its insistence on parsimony and its explicit citation of Levine and Chalmers demonstrated philosophical sophistication. The reasoning-model architecture appears to produce more conservative, carefully bounded conclusions.
