About GPT-6 Luna
GPT-6 Luna is the GPT-6 generation’s speed-and-price floor, listed on OpenRouter since September 23 at $0.10/$0.50 per million tokens with a 1.05M context (a same-price Pro tier offers higher throughput). That is half the price of GPT-5.6 Luna; the provisional AMR score is anchored to the prior Luna tier plus a generational step and stays off all track rankings until first benchmarks and throughput readings land.
