## AI 摘要

OpenAI 发布 GPT-5.6 Sol（前沿模型）、Terra（平衡日常模型）和 Luna（快速低价模型）的有限预览。swyx 测试 Sol 后给出极高评价，称这不仅是“cyber”版本，而是全新的 SOTA 工作模型，完全取代 Opus 处理他 80% 的任务。关键数据：Sol 与 Mythos Preview 竞争时仅使用约 1/3 的输出 token。swyx 指出 OAI 后训练团队大幅提升了推理帕累托前沿，且未公开方法，这已成为企业智能体模型最重要的竞争优势。他认为这次小版本升级远大于 5.4→5.5 的跳跃，甚至应直接命名为 GPT-6。

## 正文

have been testing 5.6 for a while and VERY happy with it. DO NOT view this as just a "cyber" release， it is the new sota workhorse model， completely replacing opus for 80% of tasks for me

> GPT-5.6 Sol is competitive with Mythos Preview using only ~1/3 of the output tokens.

this is a very key line. OAI posttraining team has shifted the reasoning pareto frontier by A LOT and they arent saying anything about how they did it because this is the single most important competitive advantage right now in agentic models for enterprise.

team really locked in on this one， i honestly wish they just went ahead and called it GPT6 because this minor semver bump is far larger than even the 5.4->5.5 jump which itself was the single most successful openai launch since 4o/o1
