OpenAI reportedly cuts GPT-5.6 Luna prices by 80%

A Hacker News item points to a post by Sam Altman claiming that OpenAI cut GPT-5.6 Luna pricing by 80%. The available record contains the linked social-media post and one Hacker News comment, but no independently cited OpenAI pricing page, API documentation, or detailed billing terms. The model’s capabilities, affected products, input/output pricing, geographic scope, and effective date therefore remain unclear. The announcement could be important for inference economics, but the core claim should be treated as unverified until primary pricing documentation confirms it.
