OpenAI Cuts GPT-5.6 Luna Price 80% — Chinese AI Competition Forces the Move
One-line summary: OpenAI cut GPT-5.6 Luna's API price by 80% on July 30 — three weeks after launch — a defensive move against Chinese AI models that now claim nearly half of US enterprise token usage.
Key Points
- Luna: input $1 → $0.20, output $6 → $1.20 per million tokens — effective July 30, 2026
- Terra: 20% cut ($2.50→$2 input / $15→$12 output); flagship Sol unchanged at $5/$30
- OpenAI credits Sol rewriting its own inference stack for the efficiency gains that funded the Luna price drop
- Competitive trigger: a July 7 CNBC report found Chinese AI models peaked above US-origin models on OpenRouter, capturing ~46% of US enterprise token usage
Why It Matters
An 80% price cut three weeks post-launch is not a product cycle event — it's a market concession. Frontier AI pricing power is eroding faster than most expected, driven by open-weight models from China flooding the cost-sensitive end of the API market. For enterprises: inference costs are in structural decline and switching costs between providers have never been lower.
