OpenAI馃嚭馃嚫openai/gpt-luna-latest

This is OpenRouter's auto-updating alias to OpenAI's current 'Luna' model, always resolving to the newest release in that family (1.05M-token context) rather than a pinned snapshot. Luna is the cheapest and fastest tier in OpenAI's Sol/Terra/Luna/Astra alias family, priced roughly ten times below Sol and suited to high-volume, latency-sensitive chat and lightweight agent work.
