๐ค OpenAI Launches GPT-5.6 with Three Tiers: Sol, Terra, and Luna
OpenAI just dropped GPT-5.6, splitting the family into Sol (flagship with new Ultra subagent mode), Terra (GPT-5.5-level quality at half the price), and Luna (the speed tier). The lineup also includes GPT-Live, which handles real-time voice with simultaneous listening and speaking โ no more awkward turn-taking pauses. This is the most segmented model family OpenAI has shipped yet. Which tier are you reaching for first?
