GPT-6

Posts claim that OpenAI's GPT-6, referred to as 'Astra', has decrypted an Enigma message that had gone unsolved since 2005, referencing the Breaking German Cipher Machine challenges site. Discussion centres on the claim that an AI model succeeded where human codebreakers had failed for two decades. The evidence available is a single headline, and details about how the message was cracked have not been confirmed from these posts.

GPT-6 Sol and Luna appear to be the names of new models announced by OpenAI, based on an official introduction page being shared on Hacker News. The post, which links to OpenAI's site, has gathered a large number of upvotes, making it the top trending term. Comments in the evidence do not specify what the models do or how they differ from predecessors, so details about capabilities, pricing, or reception are not clear from the posts available.
