• 我找不到「5 大」同時符合「支援香港繁體中文」及「可免費存取 GPT-5.5」的 AI 應用程式；按目前可核實資料，這個清單不成立。OpenAI 官方資料顯示，ChatGPT 免費版目前是 GPT-5.2／GPT-5.3 級別功能，而 GPT-5.5 Thinking 只列給 Plus、Pro、Business、Enterprise 等付費用戶使用，不是免費版 [7][11]。
• **ChatGPT**：支援香港繁體中文介面／內容；免費版可用，但官方免費版 FAQ 顯示免費用戶可用的是 GPT-5.2 相關能力，不是 GPT-5.5 [7]。GPT-5.5 Thinking 官方列為 Plus、Pro、Business、Enterprise 用戶可用 [11]。
