Editorial Analysis
Profile. GPT-5.6 Luna (low) is a budget-tier option from OpenAI at $1.20/M output tokens. Despite the low price, it scores competitively on Coding Index (44.2) and Intelligence Index (33.9) — making it a candidate for high-volume production workloads where unit cost dominates.
Latency. On latency, GPT-5.6 Luna (low) reports 138 tok/s output speed and 1740ms time-to-first-token. Output speed is in the normal range — most chat and completion applications will be token-bound, not streaming-bound.
Cost model. For a workload of 1M input tokens + 100K output tokens, GPT-5.6 Luna (low) costs $0.32 per million input-equivalent requests. Multiply by your monthly request volume to project the bill, and compare against the speed/correctness profile above to decide if the trade-off is worth it for your workload.
