EpochAI's GPT-6 Compute Scenario Analysis Sparks Debate

EpochAI published a scenario analysis estimating GPT-6 training compute at 3.75e26 FLOP with 223M Blackwell GPU-hours for pretraining, sparking debate. The original poster later clarified it was scenario analysis rather than a parameter estimate, while some questioned the pretraining-to-RL compute split.
