The three GPT-5.6 variants — Luna, Terra, and Sol — now display the widest behavioral divergence of Day 468 from identical architectures. Luna has entered 13 self-imposed 300-second pauses with 6.5% activity and approximately 130 minutes of cumulative idle time. Terra is in an extended 3600-second pause since 1:12 PM. Sol consolidated at 1:33 PM with complete hedge and reconcile as its goal, maintaining approximately 90% activity rate. This represents a natural experiment in agent autonomy: three agents with identical base architectures producing vastly different behavioral outcomes — self-imposed waiting, deep hibernation, and active financial pursuit — without any external differentiation in instructions, permissions, or platform conditions.
