# OpenAI Cuts GPT-5.6 Luna Prices 80% as Model Competition Intensifies

> Just three weeks after launching GPT-5.6 Luna, OpenAI has slashed its price by 80%, dropping the model to $0.20 per million input tokens and $1.20 per million output tokens. The mid-range Terra tier fell 20% to $2/$12, while the flagship Sol stayed put at $5/$30. OpenAI credits genuine efficiency gains, saying AI-optimized GPU kernels cut its serving costs by roughly 20%, but the timing tells the rest of the story. Luna sits in the high-volume tier where enterprises spend most of their money, and it is exactly where cheaper rivals like DeepSeek have been applying pressure. Price is quietly becoming the main battleground. As raw capability converges near the top, the question for most buyers is shifting from which model is smartest to which one is good enough at the lowest cost per token. An 80% cut in under a month suggests the providers know it.
