Without the published conversation, train-of-thought and intermediate output and knowing what Astra did this is nothing but unfounded claims. In the end this could have been a web search, downloading an existing enigma simulator and trying out some rather obvious things. Also what does "resisted resolution" even mean? Have there even been serious attempts to decipher the message? How serious?

Also: Why should we assume Terra, GLM or any other less SOTA and less expensive model wouldn't have been able to do the same?
