GPT-6 Astra 負責諗同執行，Higgsfield 負責出圖出片。兩樣夾埋先行得通 —— 而中間有幾個位，唔講你會蝕錢。呢版係開工之前應該知嘅嘢：真實成本、六步安裝、同埋連唔到嗰陣點算。
兩個付費訂閱，冇一個免費版夠用
好多教學跳過呢一段，但佢決定咗你做唔做得成。兩邊都要畀錢，兩邊嘅免費版都開唔到呢個流程。
- ChatGPT（跑 Astra）： 想喺一般 chat 嘅 model 清單揀到 GPT-6 Astra，要 Pro、Business 或者 Enterprise。用緊 Plus（US$20）一樣有 Astra，但淨係喺 Work 同 Codex mode 入面，唔喺一般 chat。Plus 大概每 5 個鐘得 5 至 45 個 Astra message，而一個 build 隨時行 20 至 40 分鐘 —— 即係每一句都好貴，當佢係計錢咁用。
- Higgsfield（出圖出片）： 官方寫明要有 active 嘅付費 plan，免費 web tier 開唔到個 plugin。Starter US$19／月 270 credits；Plus US$59（年繳 $47）1,200 credits；Ultra US$129（年繳 $99）3,000 credits。
唔好貪平揀 Starter。 Starter 用唔到 Seedance 2.5，而 Seedance 2.5 就係佢哋自己個旗艦產品同 UGC 示範背後嗰個 model。揀咗 Starter，呢份指南有一半你做唔到。Plus 先係真正嘅入門位。
以下所有價錢同限制，係 2026 年 9 月寫呢篇嘅時候嘅資料。呢類工具改 plan 改得好密，真係畀錢之前，自己撳入去 check 返最新。
三個會靜靜雞燒錢嘅位
- 「Unlimited」喺 plugin 度唔 work。 官方原文：經 MCP、ChatGPT plugin 或者 CLI 嘅每一次生成，都照標準價扣 credit。Unlimited 淨係喺佢哋個網站入面有效。
- 所有公佈價，都係「第一次試」嘅價。 佢哋自己個 blog 都寫，實際上一條用得嘅片，通常要試三至十次。生成咗但出嚟唔啱用，係唔會退 credit 嘅 —— 因為技術上佢成功咗。淨係完全出唔到嘢先會退返。
- 冇 hard cap。 用爆咗唔會自動停，所以個 guard 要你自己落。
換返做錢：Plus 1,200 credits 收 US$59，即係一個 credit 大約 5 美仙。一條 15 秒、1080p 嘅 UGC 廣告 270 credits，大約 US$13，食咗你成個月 22%。一條 30 秒 cinematic single take 540 credits，大約 US$27，即係成個月 45%。呢啲係佢哋自己跑出嚟公佈嘅數字 —— 記得再乘五，先係你真正會畀嘅錢。
From now on, before you generate any image or video, tell me roughly how many credits it will cost and why, then stop and wait for me to reply "OK". Generate nothing I haven't confirmed.
Before you generate, write out what you're about to make, in words: - the shot, and what's in frame - length, aspect ratio, resolution - which model, and why that one - the estimated credit cost I may want to change it. Generate only once we've settled it — don't iterate by burning generations.
六步裝好個 plugin
- 開 plugin 目錄：去 chatgpt.com/plugins，或者撳左邊 sidebar 嘅 Plugins。
- 搜尋 Higgsfield。
- 加入 plugin。
- 登入 Higgsfield。
- 用緊 ChatGPT Plus 嘅，要轉去 Work mode —— Astra 對你嚟講喺嗰度。然後打 @ 再揀 Higgsfield，就叫到個 plugin 出嚟。
- 做視覺嘢，reasoning 校去 Extra High。但如果純粹寫 code，Medium 通常抵啲 —— High 多數淨係令你等耐咗。
I want to use Higgsfield to make [what you're making]. Before we start: 1. Confirm you can actually reach the Higgsfield plugin right now 2. Tell me which model you plan to use, and why that one 3. Quote the credit cost before each generation and wait for my OK Tell me when you're ready. Don't generate anything before we've agreed the plan.
連到但係唔郁？
- 連到咗但完全冇反應： 開一個全新 conversation，第一句就直接寫明「Higgsfield」。
- 見到 Authorization with the MCP server failed： 去 Settings → Plugins → Higgsfield，reconnect 一次。
- 生成完但搵唔到： 大約 60 秒之後會落你個 Assets 度。
試吓：出一條唔似 AI 嘅 UGC
大部分 AI 片一睇就穿，因為太靚、太順、太正中。呢個 prompt 反其道而行：手機歪咗幾度冇人扶正、構圖偏少少、打字節奏唔規律、中間有停頓、由頭到尾唔望鏡頭。啲「唔完美」係要你明明白白寫出嚟，佢先做得到。
Replicate the person in the reference image exactly: face, skin detail, hairstyle and clothing, strictly as shown, adding nothing and changing nothing. Carry over the person's identity only — not the lighting. Keep the imperfections on purpose. The propped-up phone sits a few degrees crooked and she never straightens it. The framing is slightly off-centre. Keep the natural room noise: no music, no studio-style polish. She sits at a computer working, body relaxed, focused on the screen, both hands typing naturally — the rhythm irregular, pausing now and then to think. A few seconds in, one hand leaves the keyboard and reaches naturally for the coffee cup beside her, her eyes still on the screen. She takes a small sip, presses her lips together slightly, sets the cup down, and puts her hand back on the keyboard to keep typing. She never looks at the camera, never smiles for it, never poses. Keep the small movements of someone actually working: blinking, light breathing, fingers pausing, small shifts of gaze, natural changes in posture. The motion should not be too smooth or too perfect — it should look like a real clip someone caught on a phone.
用之前記住：張參考相應該係你自己，或者係同意咗畀你用嘅人。
喺 ChatGPT 入面做唔到嘅兩樣嘢
獨立嘅音訊生成同 Website Building，喺 ChatGPT 個 plugin 度係做唔到嘅。你可以喺生成條片嗰陣連對白一齊出，但單獨嘅旁白、voice cloning、配音就唔得。要做呢啲，就返去 Higgsfield 個網站，或者改為接去 Claude。
如果淨係記得一樣嘢： 所有公佈嘅價錢，先乘五，再決定條片值唔值得開工。第一次生成嘅價錢好靚，但你唔會第一次就啱。
