Rumors that OpenAI recently finished new >10T parameter training run

🚨 SCOOP: OpenAI recently finished its next pretrain, codename "Bel" - the successor to "Doug", which is expected to be the base for Astra and GPT-6 (w/ further RL) Bel is a giant pretrain with >10T total parameters, similar in size to GPT-4.5. OpenAI expect it to be a post-GPT-6 base, and potentially even the base for an AGI-threshold model. All of this has Anthropic concerned. OpenAI believe Anthropic have no good response to Astra prepared for a public launch, and my understanding is that they're correct - mostly as a result of compute constraints, Anthropic are bracing for much of the rest of the year to go OpenAI's way, but think they'll be back on top early next year.
