Incredibly impressive. Still can't really shake the feeling that this is o3 gaming the system more than it is actually being able to reason. If the reasoning capabilities are there, there should be no reason why it achieves 90% on one version and 30% on the next. If a human maintains the same performance across the two versions, an AI with reason should too.
