## AI 摘要

OpenAI 推出 GPT-5.6 系列，含旗舰 Sol、Terra 和 Luna。Sol 定价每百万 token 输入 $5、输出 $30，输出高于 Claude Opus 4.8（$5/$25），但远低于受限版 Claude Mythos 5（$10/$50）。Terra 性能与 GPT-5.5 相当，价格低 2 倍（$2.50/$15）；Luna 成本最低（$1/$6）。Sol 将于 7 月在 Cerebras 芯片上线，速度达 750 tokens/s。OpenAI 正式加入价格战。

## 正文

OpenAI priced GPT-5.6 Sol (largest Model) closer to Claude Opus 4.8 than to Anthropic’s restricted Mythos 5. Price war started.

Sol comes in at $5 input / $30 output per 1M tokens.
For comparison:

Claude Opus 4.8: $5 / $25
Claude Mythos 5: $10 / $50
GPT-5.6 Terra: $2.50 / $15
GPT-5.6 Luna: $1 / $6

That makes Sol more expensive than Opus 4.8 on output, but far below Mythos 5 on both input and output.

And: "Terra has competitive performance to GPT‑5.5 while being 2x cheaper and Luna brings strong capability at our lowest cost."

They are also releasing Sol on Cerebras-Chips:

"We're also launching GPT‑5.6 Sol on Cerebras at up to 750 tokens per second in July, bringing frontier intelligence to customers at unprecedented speed."

A truly exciting release. OpenAI is entering the price war with this one.

And I love the names: Sol, Terra, Luna. Sounds fantastic!

Hyped for the release!
