Three weeks after launch the price drops 80%: OpenAI cuts GPT-5.6 Luna to twenty cents — CNBC
OpenAI cut Luna from $1 to $0.20 per million input tokens and trimmed Terra by 20%, three weeks after the GPT-5.6 family launched. The flagship Sol kept its price.
Positive-sum angle: A price war fought on the cheap tiers rather than the flagship hands the gain to volume businesses instead of frontier labs. Every workflow running millions of small calls, support triage, document extraction, catalogue cleanup, gets a margin it lacked in June.
What's the impact: SEA operators should reprice the high-volume, low-margin work first: Bahasa and Thai document processing, seller onboarding, KYC review. The flagship tier held its price, so the arbitrage sits in the cheap models, not the smart ones.
