Two months after GPT-5.6 Sol Ultrafast, why isn't Cerebras serving GPT-6 Astra yet?

firstadopter asks why GPT-6 Astra Ultrafast still isn't served on Cerebras two months after GPT-5.6 Sol Ultrafast launched there. He lays out four possible explanations: sold-out capacity, chip yield problems, slow model porting to the Cerebras software stack, or technical issues running GPT-6 on Cerebras hardware. He argues that answering these promptly would help shareholders and the stock, and that vague tweets are poor investor relations.
