OPENAI DROPS THREE NEW MODELS ON THE WORLD TODAY AS GPT-5.6 FAMILY GOES LIVE FOR EVERYONE After weeks of restricted government preview and Trump administration vetting, OpenAI has opened the gates on its GPT-5.6 family to the general public. Three models, three price points, three different jobs. Sol handles the hardest problems — complex coding, deep research, security analysis. Terra targets high-volume business work like customer support, document analysis, and internal automation. Luna is the cheap and fast everyday option for summarization, drafting, and routine tasks. The pricing structure signals what OpenAI thinks the market wants. Sol runs $5 per million input tokens and $30 output. Terra comes in at $2.50 input and $15 output. Luna is $1 input and $6 output. OpenAI is also launching Sol on Cerebras hardware at speeds up to 750 tokens per second — the fastest frontier model inference on the market by a significant margin. What this means is that OpenAI just dropped three weapons in one day while Anthropic is managing Fable 5’s restricted rollout and Google is still weeks out from Gemini 3.5 Pro. The competitive pressure today is not just about capability — it is about who can get capable models into developer hands at the right price before the other guy does.
