OpenAI’s published model materials and help center describe GPT‑5.6 Sol as the Sol-branded model and make no mention of a separate "GPT-6 Sol" release or schedule. Current documentation and third‑party analyses consistently treat GPT‑5.6 Sol as the Sol model and GPT‑6 Astra as the next-generation system, which contradicts a claimed imminent launch of GPT‑6 Sol. Available pricing information indicates GPT‑5.6 Sol is substantially cheaper per token than GPT‑6 Astra, but also describes Astra as the more capable frontier model that succeeds Sol and offers stronger, more efficient agentic work, not the reverse. These sources show Astra is both more expensive and more capable than Sol, contradicting the claim that "GPT-6 Sol" is cheaper and more intelligent than "6 Astra.". (Only 1 of 3 AI systems responded.)
