The most-discussed OpenAI signal of the weekend came and went in minutes. An OpenAI employee reportedly posted about the difficulty of choosing between Astra and GPT-5.6 Sol in what was described as "Ultrafast mode," then deleted it — a sequence captured and amplified by @TokenGremlin before it vanished. The framing is what caught frontier-watchers' attention: not which model is better, but which to use for a given job.
