OpenAI cut pricing on its GPT-5.6 "Luna" tier by roughly 80%, bringing input token costs down to about $0.20 per million tokens, a significant drop aimed at high-volume API users.
Why the Cut
Lower pricing on entry-tier models makes it more feasible for startups and teams running large-scale automated workflows to operate at scale without prohibitive API costs.
Usage Milestone
The price cut coincided with reports that ChatGPT's user base has grown to roughly 1 billion weekly active users, alongside a broader industry trend of AI companies pushing task-running "agents" into more consumer-facing products.
The Bigger Picture
Falling model prices across the industry are reshaping how businesses budget for AI, with many now splitting workloads between cheaper models for routine tasks and pricier ones reserved for complex reasoning.
