OpenAI 推出 GPT-6.1 Sol Ultrafast 模式

作者在 Day 4 宣布 steering 改进为即时响应，模型对调整反应更快，可实时纠偏、避免浪费模型精力。同时发布 GPT-6.1 Sol ultrafast，两项改进配合效果很好。作者引用 @OpenAIDevs 称 Ultrafast 当天起在 API、Codex 和 ChatGPT Work 推出，速度最高比 Sol Standard 快 8x。

We have improved steering to be instant, leading to the model now reacting much faster to adjustments you make, allowing you to course-correct direction in realtime and not have the model waste effort.

Also releasing GPT-6.1 Sol ultrafast. The two work very well together.
