'''生成式預訓練變換模型5'''（'''GPT-5'''）是由[[OpenAI]]開發並託管的[[大型語言模型]]。作為該公司的旗艦[[代理型人工智能|代理式]]模型，GPT-5於2025年8月7日正式發佈，用戶可透過[[ChatGPT]]免費或付費使用，亦能透過[[API]]調用。<ref name=":9">{{cite web |title=Introducing GPT‑5 for developers |url=https://openai.com/index/introducing-gpt-5-for-developers/ |access-date=2025-08-07}}</ref>

[[微軟]]宣布將把GPT-5整合至[[微軟產品列表|多款產品]]中，包括[[Microsoft Copilot|Copilot]]。<ref>{{Cite web |last=Warren |first=Tom |date=2025-08-07 |title=Microsoft brings GPT-5 to Copilot with new smart mode |url=https://www.theverge.com/news/753984/microsoft-copilot-gpt-5-model-update |access-date=2025-08-07 |website=[[The Verge]] |language=en-US |archive-date=2025-08-07 |archive-url=https://web.archive.org/web/20250807214254/https://www.theverge.com/news/753984/microsoft-copilot-gpt-5-model-update |url-status=live }}</ref> 據《[[9to5Mac]]》報導，[[蘋果公司|蘋果]]也計劃將該模型整合至[[Apple Intelligence]]系統。<ref>{{Cite web |last=Hall |first=Zac |date=2025-08-08 |title=Here's when ChatGPT integration within Apple Intelligence will use GPT-5 |url=https://9to5mac.com/2025/08/07/apple-intelligence-gpt-5-chatgpt-integration/ |access-date=2025-08-10 |website=[[9to5Mac]] |language=en-US}}</ref><ref>{{Cite web |last=Axon |first=Samuel |date=2025-08-08 |title=Apple brings OpenAI’s GPT-5 to iOS and macOS |url=https://arstechnica.com/ai/2025/08/apple-brings-openais-gpt-5-to-ios-and-macos/ |access-date=2025-08-10 |website=Ars Technica |language=en}}</ref>

== 研發背景 ==
2023年4月14日，OpenAI[[執行長]][[山姆·奧特曼]]在[[麻省理工學院]]的活動中表示，公司當時並未訓練GPT-5，而是「優先開發GPT-4」，且「短期內不會發佈GPT-5」。<ref>{{cite web |date=2023-04-14 |title=OpenAI's Sam Altman Says There's No Chat GPT-5 to Worry About...Yet |url=https://gizmodo.com/sam-altman-open-ai-chatbot-gpt4-gpt5-1850337299}}</ref>

據《[[The Information (website)|The Information]]》報導，2024年下半年OpenAI內部開發代號「Orion」的模型原擬作為GPT-5發佈，但因未達預期效果，最終於2025年2月以[[GPT-4.5]]名義推出。<ref name=":8">{{Cite web |title=Inside OpenAI’s Rocky Path to GPT-5 |url=https://www.theinformation.com/articles/inside-openais-rocky-path-gpt-5 |access-date=2025-08-10 |website=The Information |language=en}}</ref>

2023年7月18日，OpenAI在美國申請「GPT-5」商標，<ref>USPTO GPT-5 Trademark Registration https://tmsearch.uspto.gov/bin/showfield?f=doc&state=4805:xgx403.2.1</ref><ref>{{cite web |date=2023-08-02 |title=OpenAI Drops Huge Clue About GPT-5 |url=https://futurism.com/the-byte/openai-trademark-gpt-5}}</ref><ref>{{cite web |date=2023-03-17 |title=GPT-5 |url=https://lifearchitect.ai/gpt-5/ |access-date=2025-08-10 |archive-date=2025-07-22 |archive-url=https://web.archive.org/web/20250722122927/https://lifearchitect.ai/GPT-5/ |dead-url=no }}</ref>同年11月13日奧特曼向《[[金融時報 (英國)|金融時報]]》確認公司已啟動GPT-5研發。<ref>{{Cite web |last=Dorrier |first=Jason |date=2023-11-15 |title=OpenAI CEO Sam Altman Says His Company Is Now Building GPT-5 |url=https://singularityhub.com/2023/11/15/openai-ceo-sam-altman-says-his-company-is-now-building-gpt-5/ |access-date=2024-01-23 |website=Singularity Hub |language=en-US}}</ref><ref>{{Cite news |last1=Murgia |first1=Madhumita |date=2023-11-13 |title=OpenAI chief seeks new Microsoft funds to build 'superintelligence' |url=https://www.ft.com/content/dd9ba2f6-f509-42f0-8e97-4271c7b84ded |access-date=2024-01-23 |newspaper=Financial Times}}</ref>

OpenAI指出GPT-5的改進包括：

* 更快的響應速度

* 強化的程式編寫與文本生成能力

* 醫療問答準確性提升

* [[幻觉 (人工智能)|幻覺現象]]減少

* 對敏感問題提供安全的高階回應而非直接拒絕<ref>{{Cite news |last=Metz |first=Cade |date=2025-08-07 |title=OpenAI Unveils GPT-5, New AI Model, to ChatGPT Users |url=https://www.nytimes.com/2025/08/07/technology/openai-chatgpt-gpt-5.html |access-date=2025-08-07 |work=[[The New York Times]] |language=en}}</ref><ref name=":7" />

== 系統架構 ==
GPT-5包含三組模型<ref>{{cite web |title=GPT-5 系統說明卡 |url=https://openai.com/zh-Hant/index/gpt-5-system-card/ |website=OpenAI |accessdate=2026-01-14}}</ref>：

奧特曼曾批評手動選擇模型過於複雜，需簡化流程。

OpenAI未公開GPT-5的能耗數據，但據測算，單次中等長度回應耗電超過18瓦時。<ref>[https://www.theguardian.com/technology/2025/aug/09/open-ai-chat-gpt5-energy-use Aisha Kehoe Down: "OpenAI will not disclose GPT-5’s energy use. It could be higher than past models"] The Guardian, 9 August 2025, retrieved 9August 2025</ref>

== 各界評價 ==
=== 專業評論 ===
《[[MIT科技評論]]》認為GPT-5「本質是產品優化而非技術突破」，對奧特曼宣稱「邁向AGI」持保留態度。<ref>{{Cite web |last=Huckinsarchive |first=Grace |date=2025-08-07 |title=GPT-5 is here.

《[[大西洋雜誌]]》讚賞其直覺性與可定制化，<ref name=":3">{{Cite web |last=Wong |first=Matteo |date=2025-08-07 |title=The New ChatGPT Resets the AI Race |url=https://www.theatlantic.com/technology/archive/2025/08/gpt-5-launch/683791/ |access-date=2025-08-09 |website=[[The Atlantic]] |language=en}}</ref> 而《[[紐約 (雜誌)|紐約]]》指出普通用戶難察顯著差異，但開發者與企業用戶感受深刻。<ref>{{Cite web |last=Herrman |first=John |date=2025-08-08 |title=What’s the Deal With GPT-5? |url=https://nymag.com/intelligencer/article/openai-gpt-5-chatgpt-first-impressions-reaction.html |access-date=2025-08-10 |website=[[New York (magazine)|New York]] |language=en |archive-date=2025-08-10 |archive-url=https://web.archive.org/web/20250810063341/https://nymag.com/intelligencer/article/openai-gpt-5-chatgpt-first-impressions-reaction.html |dead-url=no }}</ref>

=== 用戶反饋 ===

==== 路由系統爭議 ====
自動切換模型導致回應品質不穩，奧特曼坦承首日系統故障影響表現。<ref name=":1">{{Cite news |last=Forgash |first=Emily |date=2025-08-08 |title=OpenAI's GPT-5 Met With Mixed Reviews, Confusion in First Day |url=https://news.bloomberglaw.com/private-equity/openais-gpt-5-met-with-mixed-reviews-confusion-in-first-day |work=[[Bloomberg L.P.|Bloomberg]]}}</ref>

==== 舊版模型下架 ====
非專業版用戶無法使用[[GPT-4o]]等舊模型引發不滿，OpenAI承諾恢復部分訪問權限。<ref name=":5">{{Cite web |last=Roth |first=Emma |date=2025-08-08 |title=ChatGPT is bringing back 4o as an option because people missed it |url=https://www.theverge.com/news/756980/openai-chatgpt-users-mourn-gpt-5-4o |access-date=2025-08-09 |website=[[The Verge]] |language=en-US}}</ref>

==== 風格轉變批評 ====
用戶懷念GPT-4o的親切語調，批評GPT-5回應「機械化」如「過度工作的秘書」。<ref>{{Cite web |last=Whitwam |first=Ryan |date=2025-08-08 |title=ChatGPT users hate GPT-5’s “overworked secretary” energy, miss their GPT-4o buddy |url=https://arstechnica.com/ai/2025/08/chatgpt-users-outraged-as-gpt-5-replaces-the-models-they-love/ |access-date=2025-08-10 |website=Ars Technica |language=en}}</ref>
