GPT-6 Astra Rumors Swirl Over 1.2T Active Parameters

Rumors claim OpenAI's GPT-6 Astra (codename Doug) has around 1.2T active parameters out of 10T total, trained on over 150T tokens, with OpenAI confirming an August 1 math score came from Astra. Some estimate it is twice the size of Kimi K3 and wins mainly through RL data, though it lags Fable on knowledge-heavy benchmarks.
