The upgrade marks a significant leap from GPT-4, with improvements in speed, accuracy, and the ability to avoid “hallucinations” – instances where the AI invents false information.
此次升級相比GPT-4有重大躍進，在速度、準確度以及避免「幻覺」（指AI編造虛假資訊）的能力方面皆有提升。

For the first time, the free version of ChatGPT is powered by a “reasoning model,” capable of pausing to think through complex problems before answering.
這是首次在免費版ChatGPT中使用「推理模型」，能在回答前先花時間思考複雜問題。

This enhanced reasoning also makes it easier for users to create apps with minimal instructions, a feature Altman believes could reshape how people interact with technology.
增強的推理能力也讓使用者能用極簡的指令快速建立應用程式，奧特曼認為這可能徹底改變人們與科技互動的方式。
minimal(adj.)極少的、極小的、最低限度的
However, the rollout has been met with mixed emotions.
然而，外界對GPT-5推出的反應卻褒貶不一。

Many long-time users mourned the removal of older models, particularly GPT-4o, which some described as more “personable” and emotionally responsive.
許多忠實用戶對舊模型，特別是GPT-4o的下架感到不捨，有人形容GPT-4o更具「人情味」，也更有情感反應。

Online communities, including those devoted to AI companionship, shared posts comparing the change to “losing a friend.”
在包括AI伴侶社群在內的網路論壇上，有人將這次變化比作「失去一位朋友」。

Industry observers see GPT-5 as another step toward artificial general intelligence – a system capable of performing any intellectual task a human can.
產業觀察人士認為，GPT-5是邁向通用人工智慧（AGI）的又一步，AGI是一種能執行任何人類智力任務的系統。

Altman admits that AGI is still far away, but says GPT-5 offers “orders of magnitude more gains” over previous models.
奧特曼承認AGI仍有很長的路要走，但表示GPT-5相較於前代模型「有數個數量級的進步」。

Critics, however, argue that other models remain smarter in certain areas, and some users have noticed shorter or less engaging replies compared to earlier versions.
不過，批評者認為，在某些領域其他模型仍更勝一籌，也有用戶注意到GPT-5的回覆比早期版本更短，吸引力也略顯不足。
