GPT-6 Sol and Luna: half the price, same Intelligence Index

Artificial Analysis 评测 GPT-6 Sol 与 Luna：成本减半，智能指数持平

Artificial Analysis tested OpenAI's GPT-6 Sol and Luna. Both cost half as much as their GPT-5.6 equivalents: Sol at $2/$10 per million input/output tokens, Luna at $0.10/$0.50. The Intelligence Index matches GPT-5.6, so you're getting the same capability for less money. The post doesn't disclose evaluation dimensions or latency figures.

Why it matters: First third-party benchmark of GPT-6: price halved, intelligence flat. Held below 85 because it's a single-source eval — no cross-validation on sample size or task coverage yet. Treating it as a strong single signal.
