Polymarket reports that a model dubbed GPT-6 Astra cracked a 217-year-old Napoleonic military cipher, revealing a secret briefing sent to one of Napoleon's generals ahead of Austria's 1809 invasion.
Caveat: the claim comes from the prediction-market account Polymarket, not an official OpenAI channel, and "GPT-6 Astra" has no prior public footprint — treat as unverified until confirmed.
