When to send gpt-6-luna
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.
Both are OpenAI IDs. The field you change is model: gpt-6-luna or gpt-6-sol.
When to send gpt-6-sol
GPT-6 Sol keeps the 1.05M window and lists well below Astra on both input and output. Send gpt-6-sol for the same request shape at the lower GPT-6 rate.
Both are OpenAI IDs. The field you change is model: gpt-6-sol or gpt-6-luna.
