OpenAI launches GPT-6 Sol and Luna, API pricing 50% below GPT-5.6 promo rates

OpenAI 发布 GPT-6 Sol 和 GPT-6 Luna，API 价格较 GPT-5.6 促销价低 50%

OpenAI added two models to the GPT-6 family: Sol and Luna. They inherit most of GPT-6 Astra's capabilities but run faster and cheaper, with API pricing 50% below GPT-5.6 promotional rates. The post credits caching and inference efficiency gains. No benchmarks, latency figures, or rollout timeline are disclosed.

Why it matters: OpenAI added two new GPT-6 models with API pricing halved vs GPT-5.6 promo rates — a real cost signal for builders. Score held below 85 because the post lacks benchmarks, latency data, or a launch timeline; actual performance needs real-world testing.
