GPT-6 Astra rumor: 1.2T active params, trained on Abilene's 100-150k GPUs

Discussion around rumored specs for GPT-6 Astra (codename Doug): 1.2T active parameters, 10T total. OpenAI confirmed the August 1 math result came from an internal Astra version; with Abilene handing over 100-150k GPUs after Spud's (GPT-5.5) pretraining ended in late March, the pretraining run is estimated at 90-110 days.
teortaxesTex is skeptical: if 1.2T active params were truly needed, that would signal inefficiency — he estimates <350B active params, >150T tokens, and >50% of compute spent in the RL stage, while noting current models still can't help implement basic research papers. All unconfirmed speculation.
