4.6 在 Intelligence Index 從 56 拉到 61，價格卻沒跟著往上跳。這種變化我會寫進採購備忘錄。\u003C\u002Fp>\u003Cp>實操寫法很簡單：你比模型時，別只看 \u003Ca href=\"\u002Ftag\u002Fbenchmark\">benchmark\u003C\u002Fa> 排名。把 intelligence 跟 task cost

reasoning.”\u003C\u002Fblockquote>\u003Cp>這句我很認同。很多模型在乾淨 prompt、固定輸出格式裡看起來都很聰明；難的是它能不能扛住多步驟工作、工具呼叫、上下文漂移，還有中途插進來的雜訊。Grok 4.6 被放的位置，就是這種工作。\u003C\u002Fp>\u003Cp>在 GDPval-AA v2 上，它拿到 1753 Elo，僅次於 \u003Ca href=\"\u002Ftag\u002Fclaude\">Claude\u003C\u002Fa> Opus 5，跟 Claude Fable 5、Qwen3.8 Max 的信賴區間有重疊。𝜏³-Banking 是 50.7%，Terminal-Bench v2.1 是 88.4%。我會在意這種分布，因為它不是只在一個小題型上耍帥，而是能跨 knowledge work、客服、terminal 任務。\u003C\u002Fp>\u003Cp>我自己做內部支援 agent 時就遇過這種失敗模式：模型能回一封漂亮的 ticket reply，下一秒要查紀錄、整理摘要、判斷要不要升級處理，就開始亂掉。這不是抽象的「推理不夠好」，而是 agent 的紀律不夠。它得在工作流程變髒的時候，還記得自己在幹嘛。\u003C\u002Fp>\u003Cp>實操寫法：如果你的工作會碰工具、\u003Ca href=\"\u002Ftag\u002Fapi\">API\u003C\u002Fa> 或 terminal，請直接拿真實 trace 測。不要問「它答得好不好」，要問「它能不能用合理的輪數跟合理的

flat across a generation is unusual at the frontier, where intelligence gains have typically been accompanied by price increases.”\u003C\u002Fblockquote>\u003Cp>這句話很重要，因為它講的是業界常態：前沿模型通常是變強、也變貴。對寫 benchmark 文章的人來說很熱鬧，對付帳單的人來說很痛苦。Grok 4.6 把價格維持在 Grok 4.5 的 $2\u002F$6，同時把 Intelligence Index 從 56 拉到 61。\u003C\u002Fp>\n\u003Cfigure class=\"my-6\">\u003Cimg

$5\u002F$30 對照。只要你做的是推理重、輸出長的工作，output token 才是帳單主角。這就是為什麼我會把輸出價格圈起來看。\u003C\u002Fp>\u003Cp>我看過太多團隊選了「紙面最強」的模型，結果上線後又偷偷限流，因為成本扛不住。這很虧。通常更合理的做法，是挑一個能力差不多、但便宜很多的模型，因為它會被真的用起來，而不是只躺在簡報上。\u003C\u002Fp>\u003Cp>實操寫法：你可以替每個模型做一張簡單矩陣。\u003C\u002Fp>\u003Cul>\u003Cli>Frontier

~0.5B input tokens on average, against ~103 turns and ~2.0B input tokens for Claude Opus 5 (max).”\u003C\u002Fblockquote>\u003Cp>這段是我最在意的。長流程任務會把模型效率的差異放大到很難忽略。若一個模型要兩倍輪數、四倍輸入 token，單看每 token 價格就已經不夠用了。你其實是在付 context 累積、重試、以及模型自己走偏的代價。\u003C\u002Fp>\u003Cp>Artificial Analysis 還說 Grok 4.6 在 AA-Briefcase 上首次登場就拿到 1577 Elo，接近 Fable 5 等級，落在 Claude Opus 5 家族之後。這成績不差，但我更在意的是效率輪廓。53 turns 對 103 turns，不是裝飾性的差距。那代表更少 drift、更少工具呼叫、也更少上下文膨脹。\u003C\u002Fp>\u003Cp>我在研究型 agent 工作流也看過同樣的事。能把內部脈絡維持乾淨的模型，常常會比靜態 benchmark 的第一名更快交出能用的答案。對實務來說，少幾輪通常就是少幾個失敗點，也比較不會忘了你原本要它優化什麼。\u003C\u002Fp>\u003Cp>實操寫法：如果你的 agent 會跑超過幾輪，請把整條 trace 記下來，再比這四個東西：\u003C\u002Fp>\u003Cul>\u003Cli>turn count\u003C\u002Fli>\u003Cli>input tokens

很大，但別把它當萬靈丹\u003C\u002Fh2>\u003Cblockquote>“Context window of 500k tokens (unchanged from Grok 4.5).”\u003C\u002Fblockquote>\u003Cp>500k context window 當然很猛，能吃進去的材料比很多模型多很多。但我也踩過坑：大 context 不是策略，只是一個工具。你如果 prompt 寫得爛，bucket 只是讓你裝更多垃圾。\u003C\u002Fp>\u003Cp>這裡有個我會加分的地方：Grok 4.6 的 500k 跟 Grok 4.5 一樣，代表這次進步不是靠 context 作弊，而是靠模型品質跟效率本身。這比只會吹 context 的發表方式實在多了。\u003C\u002Fp>\u003Cp>我拿長 context 模型做過 codebase 分析跟文件型工作，失敗模式都很像：大家把全部資料丟進去，然後祈禱。那種做法通常死得很快。你真的要用 500k，還是得有 retrieval、chunking，還有清楚的任務結構。\u003C\u002Fp>\u003Cp>實操寫法：把長 context 拿來當參考，不要拿來當混亂的藉口。\u003C\u002Fp>\u003Cul>\u003Cli>先摘要，再推理。\u003C\u002Fli>\u003Cli>把來源資料跟指令分開。\u003C\u002Fli>\u003Cli>工具輸出要短，別讓它自己長成一坨。\u003C\u002Fli>\u003C\u002Ful>\u003Ch2>我會考慮把它放進 production 的原因很務實\u003C\u002Fh2>\u003Cblockquote>“Few models are simultaneously competitive across knowledge work, customer service and terminal use.”\u003C\u002Fblockquote>\u003Cp>這句話其實就是整篇的實務結論。對我來說，單一場景超強、其他場景普普的模型沒那麼值得追，因為 production 很少維持純淨。support、research、terminal work 一旦接上真實流程，通常就會混在一起。\u003C\u002Fp>\u003Cp>Grok 4.6 吸引我的地方，是它同時有三件我在乎的事：前沿智力、像樣的 agentic 行為、以及不太刺眼的成本結構。它沒有宣稱自己每一項都第一，但它在更像真實工作的範圍內，夠完整。\u003C\u002Fp>\u003Cp>如果是我幫團隊評估，我會先從那些模型費已經開始痛的工作下手。接著把它跟貴的前沿模型、以及便宜的中階模型一起比。問題不是「它是不是最強」，而是「它在我們真的會跑的任務裡，能不能提供更好的每美元產出」。\u003C\u002Fp>\u003Cp>實操寫法：別搞
