AI Rate CardGPT-5.6 Luna · orcarouter
GPT-5.6 Luna is the fast, cost-efficient model in OpenAI's GPT-5.6 series — tuned for high-volume, latency-sensitive workloads while retaining genuinely capable reasoning. It is well suited to chat, classification, extraction, routing, and lightweight agentic workflows where responsiveness and price per call dominate, and still serves a full 1.05M-token context window with up to 128K output tokens. It accepts text, image, and file inputs with text output, supports configurable reasoning effort so you can dial depth up for the occasional hard request, and is a first-class OpenAI Responses model with native tool calling and structured outputs. Reach for Luna at the top of a fan-out, as a cheap first-pass or draft model, or wherever you run millions of calls and every fraction of a cent and millisecond counts.
