OpenAI馃嚭馃嚫openai/gpt-6-luna:batch

This is the batch-processing variant of GPT-6 Luna, the fast, low-cost tier of OpenAI's GPT-6 series with a 1.05M-token context window, offered at half the standard token price. Requests run asynchronously, making it a good fit for very large summarization, extraction, and classification jobs that do not need real-time responses.
