A Reddit user spotted GPT 6 Sol in the OpenAI API, speculating it targets the $20 subscription tier. The rumored lineup ranks astra > sol > terra > luna by price and intelligence, mirroring Anthropic's fable > opus > sonnet > haiku structure, with astra positioned as a fable-class model for Pro subscribers and enterprises. Future releases are expected to follow a gpt 6/6.1/7 × four-tier naming matrix. Unconfirmed community sighting.
