OpenAI cuts GPT-5.6 Luna pricing by 80%
The cost of running frontier AI just dropped off a cliff. On 30 July, OpenAI cut GPT-5.6 Luna's price by 80%, to $0.20 per million input tokens — a direct saving for high-volume API workloads, internal tools, and automation-heavy flows.
OpenAI's lineup now splits into clear tiers (Luna, Terra, Sol), so teams can send routine work to cheaper models and reserve deeper reasoning for harder jobs. For businesses building on AI in ASEAN, that means production-scale assistants and document pipelines are suddenly far more affordable.
