openai has response ready for opus 5.5 whole team has started vague posting/replying about dev day and i don’t think all this hype is just for a new bot or ultra fast mode most of it seems to be around "o" and the old o models were the best at the time and people still love them so i think we might be getting whole new family: > "o" agent > gpt o6 astra > gpt o6 sol > gpt o6 luna this is the only thing that makes sense to me tbh. could be just astra minor, but i don’t think that’ll help them mog opus 5.5 at this point, i just need tomorrow to come already, can’t wait to see what team drops
