Leaker says OpenAI still uses the same base as Astra while Anthropic moved to a new one

A leaker claims OpenAI's team has long used the same base model as Astra (Doug) while Anthropic's 5.5 family uses a new base, which may force OpenAI to bring out its reserved 'bel' base.

openai hand is forced now team been using same base as astra (Doug) for while now and it's not helping them at all meanwhile anthropic is using new base model for their 5.5 family. that's how they are able to cook this harder if openai doesn't use new base model for their upcoming models they'll be cookdd openai already have new base "bel" which they been saving to use only if they are forced and i think anthropic pretty sure forced them right now with sonnet 5.5 and opus 5.5 tomorrow is openai dev day and anthropic pretty sure cooked it already unless openai releases something that would mog opus 5.5 let's see what team does tomorrow, i am still rooting for them
