AI 导读
OpenAI 发布 GPT-6 Sol 和 GPT-6 Luna，两款模型基于 GPT-6 Astra 的技术进展，把其多数能力带进更快、更便宜的模型以支持规模化工作。官方称缓存和推理效率提升，Sol 与 Luna 的 API 价格比 GPT-5.6 促销价低 50%。随文图片显示 Sol 定价为输入 $2.00、输出 $10.00，Luna 为输入 $0.10、输出 $0.50。
推荐理由
新模型把 GPT-6 Astra 的能力下放到更快更便宜的档位，API 降价给出了明确的成本参照。

Please welcome GPT-6 Sol and GPT-6 Luna to the GPT-6 universe.
GPT-6 Sol and Luna build on the advances behind GPT-6 Astra, bringing much of its strengths into faster and more affordable models to support work at scale.
We’ve also made caching and inference more efficient, and we’re passing the savings directly to you: 50% lower API prices for Sol and Luna compared with GPT‑5.6 promotional pricing.
