GPT-6 Luna is the fast, cost-efficient model in OpenAI’s GPT-6 series, positioned below GPT-6 Sol. It’s built for high-volume, latency-sensitive workloads like chat, classification, and lightweight agentic tasks, and with higher reasoning effort it can handle complex software engineering and computer-use tasks that previously required a Sol-tier model. It also inherits the GPT-6 family’s gains in factual reliability and its clearer, more concise communication style.
