  "text": "我最近開始比較大量串接 API 跑 Agent，\n後面又開始碰圖片跟影片生成之後，\n有一個問題變得越來越明顯。\n就是這些東西真的用多了之後，\n費用消耗其實非常快。\n所以我那時候很自然就開始想：\n現在開源模型都已經做到這種程度了，\n那我乾脆把模型放在自己的電腦裡面跑，不就好了？\n語言模型現在有千問、\nGemma 這些選擇，\n圖片跟影片也有越來越多模型可以自己部署。\n而且 Agent 又會一直反覆呼叫模型，\n在這樣的消耗底下，\n還不如本地的模型來去使用，\n結果真的開始研究之後，\n我第一個卡住的地方根本不是模型怎麼裝。\n而是：我要買什麼電腦？\n這件事情比我原本想像中麻煩很多。\n你開始查就會看到有人推四零九零、\n有人說直接買五零九零，\n有人覺得 AMD 同樣價格可以拿到更多記憶體，\n也有人說 Mac 的 Unified Memory\n才適合跑大模型。\n如果你本來就不是硬體玩家，\n看完這些東西其實只會更亂。\n但我後來真的開始看不同模型怎麼跑之後，\n反而發現一件事情：\n如果今天是為了本地 AI 買電腦，\n新手其實不用先研究顯卡型號。\n因為第一個真正會卡住你的東西，\n通常不是這張卡快不快是你的模型到\n底裝不裝得進去。\n而這裡第一個要看的，\n就是 VRAM。\nVRAM 簡單來說就是顯示卡自己的記憶體。\n這跟我們平常買遊戲電腦的思考方式有一點不一樣。\n像玩遊戲的時候，\n我們很常先看這張卡 FPS 多高、\n新一代快了多少。\n但是 AI 第一關會比較直接。\n假設今天一個模型跟整套 workflow\n需要的記憶體已經超過你的 VRAM，\n那這張卡算力再強，\n你還是得開始做各種妥協。\n可能把模型量化得更小、\n把一部分東西丟到系統 RAM，\n或者乾脆只能換小一點的模型，\n等於你用太小的 VRAM 時，\n你的限制就會越多。所以我現在覺得，\n買本地 AI 電腦第一個問題根本不是：\n「4090 還是 5090？」\n而是：「我到底需要多少 VRAM？」\n這個問題先確定，\n後面其實簡單很多。\n但這裡也很容易出現另外一種誤會。\n不是說今天一定要 24GB，\n低於 24GB 就完全不能跑 AI。\n如果你只是想跑比較小的語言模型，8GB、12GB、\n16GB 其實都有很多東西可以玩。\n甚至現在各種量化做得很好，\n一些原本很大的模型也可以壓到一般電腦上。\n問題是你今天想做的事情有多廣。\n如果我只想在本地跑聊天模型，\n需求其實沒有這麼誇張。\n但如果跟我一樣，\n我希望這台機器除了語言模型，\n還要跑 Coding Agent、\n圖片、ComfyUI，\n甚至連影片模型都想碰，\n那需求就會開始完全不一樣。\n以我自己來說，\n我會把 24GB 左右當成比較實際的全用途起點。\n不是因為 24GB 有什麼魔法。\n而是從這裡開始，\n你會比較少遇到「模型明明可以跑，\n但是為了塞進去，\n每一個 workflow 都要重新折\n騰一次」這種狀況。\n像 3090、4090 都是 24GB，\n而現在 5090 已經來到 32GB。\n對 AI 來說，5090 多出來的 8GB 有時候比單純\n效能提升還有感。\n因為它可能直接讓原本卡在邊界的模型或\n更長的 Context 放得進去。\n所以這也是為什麼我覺得，\n本地 AI 看顯卡不能只看快多少，\n重要是能不能運行需要的模型。\n這時，記憶體容量就是你能不能運行這類\n模型的第一個關鍵。\n這件事情到了影片模型會更明顯。\n因為一個影片 workflow 很多時候\n不只有主要生成模型。\n你可能還有 Text Encoder、\nVAE、LoRA，\n甚至其他前後處理。\n像 Wan 2.2 官方自己的 720p 單卡推理範例，\n就直接把 24GB VRAM 當成可以執行的級距。\n但這也不是代表所有影片模型一定需要 24GB。\n現在很多模型透過量化、\nCPU offload，\n甚至社群特別做的版本，\n16GB 一樣可以硬塞進去。\n像 MiniMax H3 現在甚至已經有人\n把消費級 16GB、\n24GB 的部署方式做出來。\n所以我覺得這裡真正要理解的不是某個固定數字。\n而是：能跑，跟跑得舒服，是兩件事情。\n16GB 可能透過很多優化真的跑成功。\n但是如果我今天每天都要用它工作，\n每一個新模型都要研究半天怎麼省 VRAM，\n那我自己就不會把這個叫做很舒服的配置。\nWan 2.2 官方的 720p TI2V\n範例就是至少 24GB VRAM；\nMiniMax H3 官方原始部署\n甚至以多 GPU 為主，\n消費卡之所以能跑，\n很多是後來靠量化與 offload 把門檻壓下來。\n更重要的是，\n像是量化模型通常會有犧牲掉的品質或者能力，\n這未必是一件好事。所以如果有人跟你說：\n「我 16GB 就什麼都能跑。」他不一定錯。\n但你要先問的是：\n他到底怎麼跑？\n跑多快？\n為了跑起來犧牲了多少東西？\n這比單純看到「成功運行」重要很多。\n那等到 VRAM 大概確定之後，\n我第二個會看的，\n才是這張卡後面的軟體生態。這也是為什麼\n如果今天是一個完全的新手，\n要我推薦一條比較少踩坑的路，\n我現在還是會比較偏 NVIDIA。\n原因不是 AMD 的卡不能跑，\n而是 NVIDIA 有一套叫做 CUDA 的東西。\n你可以先把它理解成：\n很多 AI 軟體跟顯示卡溝通時，\n最常用的一套環境。\n現在很多 AI 工具、新模型，尤其圖片、\n影片這一類，開發者第一個測試的通常就是\nNVIDIA 加 CUDA。\n所以你實際使用的時候，\n差別不一定只是速度。\n而是同一個模型，\n別人用 NVIDIA 可能照教學裝一裝就可以跑，\n你換成別的平台，\n有時候還要自己處理相容性、\n版本，甚至某些功能根本還沒支援。\n這個差距在單純跑語言模型時可能沒那麼明顯，\n但開始碰 ComfyUI、圖片、影片，\n尤其剛出的新模型，\n就會比較有感。\n所以我覺得 NVIDIA 很大一部分的優勢，\n其實不是顯卡本身，\n而是它後面那整套 CUDA 生態。\n至於 AMD 當然不是不能用。\nAMD 也有自己對應的環境，\n叫 ROCm，現在支援已經比以前完整很多，\n很多主流 AI 工具也都能跑。\n只是如果今天是新手，\n我會比較建議你先確認自己固定要用哪些模型、\n哪些工具，再決定要不要選 AMD。\n因為用比較低的價格拿到更多 VRAM 當然很香，\n但前提是你要用的東西真的都有支援。\n不然最後省下硬體的錢，\n卻花很多時間在處理環境跟相容性，\n使用體驗反而會變差。\n那 Apple 相關產品這邊就比較特別。\n如果今天主要是跑語言模型，\n確實是可以考慮 Mac 相關的產品。\n因為現在 Mac 用的 M 系列 這些晶片，像是 M1、M2，\n其實都是 Apple 自己設計的，\n這整套架構就叫 Apple Silicon。\n它跟一般桌機一個很大的差別，\n是 CPU 跟 GPU 可以共用同一塊記憶體。\nApple 把這個叫做 Unified\nMemory，也就是統一記憶體。\n一般 NVIDIA 電腦通常是系統 RAM\n跟顯示卡 VRAM 分開算。\n假設你今天買一張 24GB 的 4090，\n模型主要可以直接放進 GPU 的空間\n就是這 24GB。\n但 Mac 不太一樣，\n它可以直接做到 64GB、\n128GB，甚至更高的共享記憶體，\nCPU 跟 GPU 都可以使用。\n所以如果今天碰到的是非常大的語言模型，\nMac 反而有一個很特殊的優勢。\n因為有些模型不是電腦完全算不動，\n而是一般消費級顯卡的 VRAM 根本放不下。\n這時候高記憶體的 Mac，\n就有機會直接把更大的模型放進去跑。\n所以如果今天我的工作主要是 Local LLM，\n我其實真的會把 Mac 放進選項。\n而且現在也不只是語言模型。\n像 MiniMax H3 這種很大的影音模型，\n現在也已經有人真的在 M 系列 Mac 上面跑通。\n只是這裡就要講到 Apple 跟\nNVIDIA 另外一個很大的差別。\n前面講 NVIDIA 的時候有提到 CUDA，\n你可以把 CUDA 理解成目前很多 AI 軟體\n最常使用的一套 GPU 運算環境。\nApple 沒有 CUDA，\n它有自己的一套系統。\n像 Metal 是 Apple 讓程式\n使用 GPU 的底層技術，\nMLX 則是 Apple 做給機器學習使用的框架。\n其實一般使用者不用記這些名字，\n真正要知道的只有一件事情：\n同一個 AI 模型，\n在 NVIDIA 上可以跑，\n不代表直接搬到 Mac 就一定可以跑。\n很多模型需要有人另外把它適\n配到 Apple 的環境，\n或者做成專門給 Mac 使用的版本。\n這也是為什麼我覺得本地 AI 有一個很重要的觀念：\n跑得動，跟適不適合拿來工作，是兩回事。\n像 MiniMax H3 現在 Mac 確實可以跑，\n這件事情本身很厲害，\n也代表 Apple 在本地 AI 這一塊已經\n不是只能跑語言模型。\n但是如果我今天的工作是大量做圖片、\nComfyUI、影片生成，\n而且新的模型一出來我就想馬上拿來測，\n那目前我自己還是會比較偏 NVIDIA。\n因為很多新模型跟新的 workflow，\n通常還是先在 CUDA 上面被完整測試。\nNVIDIA 很可能照著官方或者社群\n教學就可以開始跑，\nMac 有時候則要等別人移植、\n調整流程，或者自己處理一些相容性的問題。\n所以 Apple 不是不能跑 AI，\n比較準確的說法是：\n如果主要跑大型語言模型，\nMac 的大容量共享記憶體其實非常有吸引力；\n但如果圖片、影片、ComfyUI、新模型全部都想玩，\n目前 NVIDIA 的整體生態還是比較省事。\n因為我買一台工作機，\n在意的不是「網路上有沒有人成功跑過一次」。\n我更在意的是，\n我每天真的要用這些東西的時候，\n到底麻不麻煩。\n那講到這裡，其實還有一個界線要先說清楚。\n前面我們一直在講 24GB、\n32GB，甚至 Mac 的大記憶體，\n這些都還是一般人真的有可能買回家的機器。\n但如果今天你的目標是：\n我要在家裡直接跑完整版的超大型模型。\n那就完全是另外一個等級了。\n像現在 DeepSeek V4 Flash 這種模型，\n雖然它每次回答的時候只會動用其中一部分，\n但整套模型本身還是非常大。\n你可以把它想成一間很大的公司，\n一次工作可能只叫幾個部門出來，\n但其他部門還是得存在。\n所以如果真的要完整部署這種模型，\n通常就不是買一張 5090 可以解決，\n而是會開始進到多張資料中心 GPU、\n伺服器這種等級。\n像 GB200、\nB200 這些當然很強，但價格、耗電、\n散熱跟整套機器都已經不是一般使用\n者會考慮的東西。\n所以我覺得一般人在玩 Local AI，\n大部分指的都是所謂的量化版本的模型，\n所以不需要追求：\n「最大的模型我也一定要滿血跑。」\n我們比較實際的做法，\n本來就是找適合自己的硬體 GPU，\n然後挑選適合的量化模型。\n只要它已經可以完成我的工作，\n那麼就是一個值得投資的考量了\n那回到一般人的工作機，\n顯卡選完之後，\n我自己還會補兩個東西。\n第一個是系統 RAM。\n前面 VRAM 是顯示卡自己的記憶體，\nRAM 則是整台電腦平常在用的記憶體。\n如果我都已經組到 24GB VRAM 這種等級，\n我自己通常會直接抓 64GB RAM。\n不是因為 32GB 不能用，\n而是實際工作時你不可能只開一個模型。\n瀏覽器、IDE、\nAgent、ComfyUI 都可能一起跑，\n而且模型太大塞不進 VRAM 的時候，\n有些東西還可以暫時丟到系統 RAM。\n這種做法通常會比較慢，\n但至少可以讓一些原本塞不下的模型跑起來。\n所以 64GB 對我來說比較像是留一點空間，\n不要每次換模型都開始撞牆。\n還有像是前面提到的 Mac 也是同概念，\n只是會直接整個記憶體考量而已。再來就是 SSD。\n這個真的玩本地 AI 之後很容易爆。\n因為模型十幾 GB、\n幾十 GB 很正常，\n圖片跟影片還會再加 VAE、\nLoRA、Encoder，\n各種版本全部累積起來會大量的吃滿空間，\n用一般儲存會影響到載入這些東西的速度。\n而且你一定不會只抓一個模型。\n所以如果真的要長期把這台當 AI 工作機，\nSSD 我也會盡量抓高一點。\n所以綜合前面這些條件，\n如果今天是我自己要組一台比較全面的\n本地 AI 工作機，\n我目前還是會優先選 NVIDIA，\n而且 VRAM 我會從 24GB 左右開始看。\n原因很簡單，一個是 CUDA 生態現在還是比較完整，\n很多新的模型、\nComfyUI workflow 跟影音\n工具通常都先支援 NVIDIA；\n另外就是 24GB 這個級距，\n已經可以涵蓋不少語言、\n圖片跟部分影片模型，\n不會每碰到一個新模型就先卡在 VRAM 不夠。\n有預算的話，32GB、\n48GB 當然會更舒服，\n但這就看每個人的預算。\n再來是系統記憶體。\n如果顯卡都已經選到這個等級，\n我自己會建議至少 64GB RAM。\n因為實際跑模型的時候，\n不只是 GPU 在工作，系統本身、Agent、\nComfyUI、瀏覽器，\n甚至模型 offload 都可能一起吃到 RAM。\n最後就是 SSD，\n這個我也不會省太多。\n就如前面說的，\n載入初始化的模型，\n很容易就可以吃掉大量空間，\n而且 SSD 的速度也會直接影響模型第\n一次載入的時間。\n所以如果要把它簡化成三件事情：\nGPU 跟 VRAM，\n主要決定模型能不能順利跑，\n以及跑得多快。\nRAM，決定系統有沒有足夠空間去載入、\noffload 跟同時處理其他工作。\nSSD，決定你能放多少模型，\n以及模型載入時要等多久。\n如果只是要我直接給一套比較不容易踩雷的方向，\n那我目前會是：NVIDIA、24GB VRAM 起跳、\n64GB RAM，\n再準備夠大的 SSD。\n這不是唯一答案，\n但如果今天目標是語言、圖片、影片、\nAgent 都想碰，\n而且希望新模型出來不要每次先處理\n一堆相容性問題，\n我覺得這是目前比較實際的一個起點。",
