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.

OpenAI has announced GPT-6, introducing two variants named Sol and Luna. The announcement is the company's latest step in its line of large language models, and details about capabilities and availability are expected to draw close attention from developers and the wider tech industry.

OpenAI has replaced its GPT-6 Sol model with GPT-6.1 Sol just seven days after the original release, with the update described as approaching the intelligence level of rival model Astra. The unusually fast turnaround is drawing attention to the accelerating pace of AI model releases and the intensifying race to close capability gaps between leading labs.
