<h2 class="wp-block-heading"><strong>GPT-5：AI 智能的新里程碑</strong></h2>



<p class="">2025 年 8 月 7 日，OpenAI 正式推出 GPT‑5，這是迄今為止智慧最卓越、速度最快、應用最廣泛的語言模型。它標榜如 PhD 等級專家般的表現，進一步縮短與人工智能通用（AGI）的距離，卻依然承認尚未達到不斷自主學習的能力<a href="https://www.wired.com/story/openais-gpt-5-is-here?utm_source=chatgpt.com" target="_blank" rel="noreferrer noopener">WIRED</a><a href="https://www.theverge.com/openai/748017/gpt-5-chatgpt-openai-release?utm_source=chatgpt.com" target="_blank" rel="noreferrer noopener">The Verge</a>。</p>



<h3 class="wp-block-heading">一、重大更新與核心功能亮點</h3>



<h4 class="wp-block-heading">1. <strong>統一模型結構：智慧導路選擇最佳模型</strong></h4>



<p class="">GPT‑5 採用「路由器」機制，根據題意簡繁自動決定使用哪個變體：快速應答模式、一層更深思考模式（GPT‑5 Thinking）、或極致推理版本（GPT‑5 Pro），提升效率與準確度<a href="https://openai.com/index/introducing-gpt-5/?utm_source=chatgpt.com" target="_blank" rel="noreferrer noopener">OpenAI+1</a>。</p>



<figure class="wp-block-image size-large"><img decoding="async" width="1024" height="619" src="https://huijou.com/wp-content/uploads/2025/08/image-1024x619.png" alt="" class="wp-image-2718" srcset="https://huijou.com/wp-content/uploads/2025/08/image-1024x619.png 1024w, https://huijou.com/wp-content/uploads/2025/08/image-300x181.png 300w, https://huijou.com/wp-content/uploads/2025/08/image-768x464.png 768w, https://huijou.com/wp-content/uploads/2025/08/image-447x270.png 447w, https://huijou.com/wp-content/uploads/2025/08/image.png 1494w" sizes="(max-width: 1024px) 100vw, 1024px" /></figure>



<h4 class="wp-block-heading">2. <strong>跨領域能力大幅提升</strong></h4>



<ul class="wp-block-list">
<li class=""><strong>程式碼與前端開發能力</strong>：強化在複雜程式碼生成、前端設計美感等方面的表現，內部測試中在 SWE‑Bench 和 Aider Polyglot 等基準上均勝過 o3 模型<a href="https://openai.com/index/introducing-gpt-5/?utm_source=chatgpt.com" target="_blank" rel="noreferrer noopener">OpenAI+2WIRED+2</a>。</li>



<li class=""><strong>創意思維與寫作</strong>：不論是自由詩、演講稿、電子郵件，GPT‑5 都能展現更具文學張力、風格一致的寫作能力，降低浮誇應答（sycophancy）<a href="https://openai.com/index/introducing-gpt-5/?utm_source=chatgpt.com" target="_blank" rel="noreferrer noopener">OpenAI+1</a>。</li>



<li class=""><strong>健康與醫療領域</strong>：在 HealthBench、HealthBench Hard 等基準上大幅領先前代模型，具備更高精準度與責任感，並主動提醒可能風險<a href="https://openai.com/index/introducing-gpt-5/?utm_source=chatgpt.com" target="_blank" rel="noreferrer noopener">OpenAI+1</a>。</li>
</ul>



<h4 class="wp-block-heading">3. <strong>多模態與上下文理解能力突破</strong></h4>



<p class="">支援文字、圖像，甚至可能涵蓋影音等多模態輸入；上下文理解窗口擴增至高達 256,000 或更高的 tokens，讓大型文檔、長對話也能一次掌握<a href="https://www.wired.com/story/openais-gpt-5-is-here?utm_source=chatgpt.com" target="_blank" rel="noreferrer noopener">維基百科+3WIRED+3WIRED+3</a>。</p>



<h4 class="wp-block-heading">4. <strong>更低幻覺率與信任度提升</strong></h4>



<p class="">GPT‑5 的幻覺（hallucination）率明顯下降，更能判斷自身無法完成任務時明確說明，提升透明度與安全性<a href="https://openai.com/index/introducing-gpt-5/?utm_source=chatgpt.com" target="_blank" rel="noreferrer noopener">OpenAI+4OpenAI+4OpenAI+4</a>。另外，OpenAI 引入「Safe Completions」（安全完成策略），在不確定時會給出安全、部分或高層級回答，並清楚說明原因<a href="https://openai.com/index/introducing-gpt-5/?utm_source=chatgpt.com" target="_blank" rel="noreferrer noopener">OpenAI+1</a>。</p>



<h4 class="wp-block-heading">5. <strong>客製化與人性化互動</strong></h4>



<p class="">提供四種預設人格：如「諷刺型」、「理性支援型」等，用戶只需選擇風格即可，增添互動趣味與效率<a href="https://openai.com/index/introducing-gpt-5/?utm_source=chatgpt.com" target="_blank" rel="noreferrer noopener">OpenAI</a><a href="https://www.wired.com/story/openais-gpt-5-is-here?utm_source=chatgpt.com" target="_blank" rel="noreferrer noopener">WIRED</a>。</p>



<h4 class="wp-block-heading">6. <strong>費用與取得方式</strong></h4>



<ul class="wp-block-list">
<li class=""><strong>ChatGPT 中即用</strong>：GPT‑5 現為預設模型，免費/Plus/Pro/Team/Enterprise 各有不同使用上限與支援 <a href="https://openai.com/index/introducing-gpt-5/?utm_source=chatgpt.com" target="_blank" rel="noreferrer noopener">OpenAI+2WIRED+2</a>。</li>



<li class=""><strong>API 提供多版本</strong>：包含 <code>gpt-5</code>、<code>gpt-5-mini</code>、<code>gpt-5-nano</code>，並支援 <code>reasoning_effort</code> 及 <code>verbosity</code> 等新調節參數，方便開發者按需選擇速度或深度<a href="https://openai.com/index/introducing-gpt-5-for-developers/?utm_source=chatgpt.com" target="_blank" rel="noreferrer noopener">OpenAI+7OpenAI+7WIRED+7</a>。</li>



<li class=""><strong>第三方整合</strong>：GitHub Copilot、Visual Studio Code 等工具已整合 GPT‑5，提升開發者工作流程<a href="https://news.microsoft.com/source/features/ai/openai-gpt-5/?utm_source=chatgpt.com" target="_blank" rel="noreferrer noopener">Source+1</a>。</li>
</ul>

<h2 class="wp-block-heading"><strong>二、GPT-5 的使用方法概覽</strong></h2>



<p class="">以下以使用者與開發者視角簡述操作方式：</p>



<h3 class="wp-block-heading">A. <strong>聊天平台（ChatGPT）使用指南</strong></h3>



<ol class="wp-block-list">
<li class="">直接輸入問題，即可由 GPT‑5 自動處理，選擇最適模式回覆。</li>



<li class="">若希望深度推理，輸入「think hard about this」等提示，或手動選擇「GPT‑5 Thinking」模式。</li>



<li class="">Pro 用戶可解鎖 GPT‑5 Pro 模式，處理最複雜問題。</li>



<li class="">自訂聊天風格：於設定中選擇預設人格。</li>
</ol>



<h3 class="wp-block-heading">B. <strong>開發者透過 API 使用 GPT-5</strong></h3>



<ol class="wp-block-list">
<li class="">選擇模型版本：標準 / mini / nano。</li>



<li class="">使用參數：
<ul class="wp-block-list">
<li class=""><code>reasoning_effort</code>：設定 minimal / low / medium / high 推理深度。</li>



<li class=""><code>verbosity</code>：設定回答詳略（low / medium / high）。</li>
</ul>
</li>



<li class="">整合工具調用能力更強，亦支持 custom tool、並行工具調用與進度提示。</li>



<li class="">上下文窗口長，適合處理大型內容。</li>



<li class="">可接入 Microsoft 生態（Copilot、Azure AI Foundry 等）。</li>
</ol>
