OpenAI 终于放出 GPT-5.6 预览，Sol 在编程和网络安全测试上效率高，Terra 半价达 GPT-5.5 水平，想尝鲜可以关注。
OpenAI 开放了 GPT-5.6 模型家族的有限预览，包括旗舰版 Sol、性价比版 Terra 和快速版 Luna。Sol 引入最大推理努力和超模式，使用子代理加速复杂任务，在 Terminal-Bench 2.1 上领先，并在网络安全基准上匹配 Mythos Preview 性能，仅用三分之一输出令牌。系统卡将网络和生物能力评为高，但低于自主全链利用的关键阈值。更广泛可用性计划在未来几周内推出。

OpenAI opened a limited preview of the GPT-5.6 model family today.
Sol is the flagship frontier model. Terra delivers GPT-5.5 performance at half the cost. Luna is the fast, affordable option for high-volume work.
Sol introduces max reasoning effort for deep reasoning and a new ultra mode that uses subagents to accelerate complex tasks. It leads on Terminal-Bench 2.1 for command-line workflows and shows strong efficiency gains in cybersecurity benchmarks, matching Mythos Preview performance using only a third of the output tokens.
The system card rates cyber and biology capabilities as high but below the critical threshold for autonomous full-chain exploits. Broader availability planned for the coming weeks. https://t.co/OFq4z0BGLe
