## Verdict

GPT-6 Luna Pro (batch) offers OpenAI's latest reasoning architecture at 90% lower cost than real-time endpoints, making it the go-to for high-volume workflows where 12-24 hour latency is acceptable. The million-token context window handles book-length documents and large codebases in a single pass. Trade-off: batch processing means no streaming and delayed results. Reach for this when you're processing thousands of requests overnight and cost per token matters more than instant feedback.
