GPT-6 Luna API pricing

Compare the published GPT-6 Luna (gpt-6-luna) list rate with corouter's outlet rate, and estimate a monthly token bill. GPT-6 Luna keeps the 1.05M window and lists above GPT-6 Sol on output, without the Code tag. Send gpt-6-luna when you want that ID rather than gpt-6-sol or gpt-6.1-sol.
