2023年下半年,ComfyUI 以其快速、流暢的影像生成能力,結合多樣的自定義節點,迅速在創作者中流行起來。ComfyUI 的亮點就是能夠批次化生成影像,一鍵載入大量工作流,讓使用者可以輕鬆實現人像生成、背景替換、風格遷移和影像動畫化等功能。越來越多的企業及個人開發者希望藉助 ComfyUI 能力進行 AI 繪畫領域創業或者業務上新,獲得高流量及商業價值,但使用原生的 ComfyUI 仍然存在一些問題:
1.顯示卡資源昂貴且難以購買:GPU 卡池管理技術門檻高:高效能的 GPU 資源不僅價格昂貴,而且往往難以大規模採購。此外,GPU 卡池的有效管理和維護需要複雜的技術支援,也帶來了額外的挑戰。
2.難以應對高併發:原生的 ComfyUI 出圖需要排隊,併發處理能力有限。在面對高併發場景時,尤其是併發請求具有大的波動性時,資源配置難以精確預測,從而可能導致系統錯誤和業務中斷。
3.門檻高,難以對外透出:ComfyUI 擁有一定的門檻,對於普通的創作者而言幾乎無法使用,需要對其進行二次包裝才能讓更多使用者享受到 AI 的便捷。
為了幫助使用者高效率、低成本應對企業級複雜場景,以下介紹 ComfyUI API Serverless 版解決方案,透過使用該方案,使用者可以充分利用 ComfyUI + Serverless 技術優勢快速開發上線 AI 繪畫應用,期待為廣大開發者 AI 繪畫創業及變現提供思路。

方案優勢
在以往的活動中,我們也面臨了很多非技術相關的使用者期望享受 AI 的魅力。結合實際需要我們給出了 Serverless 化的 ComfyUI 實踐案例,解決了上述問題。
- 部署簡單:提供基礎 ComfyUI 映象,不需要修改時一鍵即可拉起出圖,需要修改時也只需要修改 ComfyUI 映象地址即可
- 彈性 GPU:函式計算提供了 GPU 彈性的能力,根據實際請求控制例項個數,有突發流量時自動彈新例項承接請求,完全不需要增加額外的關注
- 按量付費:函式計算的按量例項為毫秒級粒度的計費策略,用多久就收多少錢,確保每分錢都花在刀刃上
- ComfyUI Serverless 化改造:對原本不適應 Serverless 彈效能力的 ComfyUI 改造,使其可以支援非同步、併發、彈性等各種 Serverless 能力
- 前後端聯動:活動開源了一個支援自定義引數,並且併發出圖的前端頁面,可直接提供給客戶使用
應用場景
ComfyUI 提供了非常高的自由度和靈活性,支援定製化工作流,並且可以重複使用,批次出圖,特別適用於需要創意影像生成場景:
- 藝術創作與設計:藝術家和設計師可以利用 ComfyUI 生成獨特的藝術作品,包括概念藝術、插畫、海報設計等。透過 ComfyUI,他們可以根據自己的創意想法生成初步的影像草稿,然後再進一步細化和完善。
- 內容製作與營銷:在社交媒體、廣告和營銷領域,ComfyUI 可用於快速生成符合品牌風格的視覺素材,用於社交媒體內容、廣告橫幅、海報等
- 遊戲開發:遊戲開發者可能利用 ComfyUI 自動生成遊戲內的景觀或建築物的紋理,減少手工製作這些元素所需的時間和成本。
- 視覺特效與影視後期:電影和電視行業的視覺特效團隊可以使用 ComfyUI 來輔助建立逼真的背景、特殊效果或修復舊影片中的畫面缺陷。
透過 API 介面呼叫 ComfyUI 解決方案
常規的 ComfyUI 出圖的流程大致如下
- 呼叫
/prompt
介面,發起出圖任務 - 透過 WebSocket 獲取出圖進度
由於在 Serverless 場景下,無請求的時候例項會被凍結,因此 WebSocket 請求是必須要存在的,且需要保持連線到出圖完成。
在併發請求數比較大的情況下,我們往往期望可以利用 Serverless 的彈性,動態建立多個函式例項處理出圖任務。但由於 ComfyUI 本身是“有狀態”的,難以確保出圖的請求和獲取狀態的請求固定打到同一個例項上,這可能會導致介面的呼叫不符合預期。
為了讓 ComfyUI 更加適配 Serverless 模式,需要針對 ComfyUI 進行一定的改造。
參考 fc-comfyui/src/images/agent 的程式碼,在 ComfyUI 映象裡內建 agent 程式,負責轉換 ComfyUI 請求並且拉起 ComfyUI。
注意!
我們提供的程式碼僅用於運營活動使用,作為 Serverless 方式呼叫的實踐參考。
功能未經過嚴格測試,請根據實際的業務需要開發或調整相關的程式碼,並構建 ComfyUI 映象。
目前提供的 Agent 能力介紹
開啟 Agent 能力,需要增加環境變數
USE_AGENT
:1
當透過 Agent 的 API 呼叫時,建議您調整單例項併發度為 1 ~ 5,確保併發請求儘量使用單獨的例項,提高出圖效率
資料型別
出圖 Prompt
與 ComfyUI 在 Dev Mode 匯出的檔案一致
type TPromptNode struct {
Inputs map[string]any `json:"inputs"`
ClassType string `json:"class_type"`
Meta map[string]any `json:"_meta"`
}
type TPrompt map[string]TPromptNode
LoadImage 節點的引數做了特殊處理,如果內容為 base64 或 http 地址,會自動將對應的檔案上傳,並轉換為 ComfyUI 可識別的形式
進度
// key 為 node id 的 map 物件
type TProgress map[string]TProgressNode
type TProgressNode struct {
Max int `json:"max"` // 進度的最大值
Value int `json:"value"` // 當前進度
Start int64 `json:"start"` // 開始時間
LastUpdated int64 `json:"last_updated"` // 最後一次更新時間
Images []TProgressNodeImage `json:"images"` // 當前節點輸出的圖片資訊(路徑)
Results []string `json:"results,omitempty"` // 當前節點輸出的圖片 base64
}
介面
出圖請求(HTTP 同步)
路徑:/api/run
Body:json 格式的 prompt 資料
返回值:最後一次的進度(包含圖片資訊)
當需要非同步請求時,需要增加 X-Fc-Invocation-Type
和 task-id
,前者告知 FC 非同步形式呼叫,後者用於記錄當前任務的唯一 id,方便後續獲取狀態
curl http://xxxxx/api/run -v \
-H 'X-Fc-Invocation-Type: Async' \
-H "task-id: abcdefg" \
-XPOST \

呼叫方式
同步呼叫
/api/run
和 /api/run/ws
都是同步介面,直接呼叫即可,區別在於是否需要出圖進度
- 在 WebSocket 內部獲取:只呼叫
/api/run/ws
- 不關心出圖進度 / 起另一個執行緒獲取進度:使用
/api/run
+/api/status
注:當選擇
/api/run
+/api/status
方式時,您需要掛載一個 NAS 例項或改造程式碼,將狀態存放至 OTS 等資料庫,否則在多例項時無法獲取進度
非同步呼叫
呼叫 /api/run
介面,並且新增 HTTP Header,藉助函式計算自帶的能力,將請求轉換為非同步形式
- Key:
X-Fc-Invocation-Type
- Value:
Async
注:當選擇非同步呼叫時,您需要掛載一個 NAS 例項或改造程式碼,將狀態存放至 OTS 等資料庫,否則在多例項時無法獲取進度
二次開發
我們提供的 agent 僅用作參考,正式使用時,請根據業務需要進行二次開發
狀態儲存
在 src/images/agent/pkg/store/fs.go
中,我們實現了基於檔案系統的狀態儲存,您只需要掛載 NAS 系統,確保檔案可被正常持久化,既可以在多個例項之間共享狀態檔案,確保可以正確拿到狀態資訊
更好的做法是,將狀態資訊寫入到 OTS、MySQL 等資料庫中,您只需要仿照 fs.go
實現 Stroe
介面針對其他資料庫的實現即可
// Store KV 資料儲存
type Store interface {
// Save 儲存 value 到 key
Save(key string, value string) error
// Load 從 key 載入 value
Load(key string) (string, error)
}
Output 節點
目前,agent 僅針對 SaveImage 節點做了特殊處理,提取其中的圖片資訊。對於特殊的業務需要,您可能需要更加定製化的工作流處理,如
- 增加更多對於 Output 的解析
- 不解析圖片節點,而是藉助於其他介面獲取圖片檔案
case "execution_error", "executed":
// 節點執行結束
log.Debugf("%s node %s finished", logPrefix, nodeid)
// 節點已完成時,修改下 Max 和 Value 至少為 1
if currentNodeProgress.Max == 0 && currentNodeProgress.Value == 0 {
currentNodeProgress.Max = 1
currentNodeProgress.Value = 1
}
if promptNode.ClassType == "SaveImage" && msg.Data.Output.Images != nil && len(msg.Data.Output.Images) > 0 {
// 如果是圖片節點,則記錄一下圖片資料
if currentNodeProgress.Images == nil {
currentNodeProgress.Images = make([]store.TProgressNodeImage, 0, len(msg.Data.Output.Images))
}
for _, img := range msg.Data.Output.Images {
currentNodeProgress.Images = append(currentNodeProgress.Images, store.TProgressNodeImage{
Filename: img.Filename,
SubFolder: img.SubFolder,
Type: img.Type,
})
}
}

與 Agent 對應,我們也給出了一份前端頁面
devsapp/fc-comfyui-couple-photo
在這裡,我們針對 ComfyUI 的 prompt 做了一些特殊的約定,以適應自定義需要。
以函式計算支援活動 “阿里雲X優酷江湖創作大賽” 為例,我們提供了預定義的 prompt 檔案
[
{
"title": "破次元壁合照",
"prompt": {},
"params": [
{
"type": "group",
"title": "STEP 1 - 上傳您的照片",
"children": [
{
"type": "image",
"id": "10",
"key": "image",
"title": "參考圖",
"description": "請上傳您的照片,幫助模型理解您的樣貌。請儘量選擇背景簡單、主體突出的半身照,不要佩戴墨鏡、帽子等可能影響您特徵的衣物。"
},
{
"type": "string",
"id": "24",
"key": "text",
"title": "參考形象描述",
"description": "為了確保模型更好地理解您的特點,您可以使用提示詞來加強模型對您的印象(請使用因為描述)。"
}
]
},
{
"type": "image",
"id": "11",
"key": "image",
"title": "STEP 2 - 選擇角色",
"description": "請選擇您希望合照的角色。",
"options": [

]
},
{
"type": "image",
"id": "12",
"key": "image",
"title": "STEP 3 - 上傳背景圖",
"description": "請上傳您期望的合影地點的圖片,這將作為背景圖片的參考。"
}
]
},
{
"title": "背景替換",
"prompt": {},
"params": [
{
"type": "image",
"id": "10",
"key": "image",
"title": "STEP 1 - 選擇角色",
"description": "請選擇您希望合照的角色。",

"id": "12",
"key": "image",
"title": "STEP 2 - 上傳背景圖",
"description": "請上傳您期望的合影地點的圖片,這將作為背景圖片的參考。"
}
]
}
]
透過 params
欄位,約定了如何渲染頁面並允許使用者填入自己的引數
export type ComfyUIPromptEditPanel = {
type: 'image' | 'select' | 'number' | 'string' | 'group'; // 資料型別
id?: string; // 對應 prompt 中的 node id
key: string; // 要修改的引數
title: string; // 標題
description?: string; // 描述
options?: string[] | string; // 可選項
min?: number; // 最小值
max?: number; // 最大值
step?: number; // 調整步數
hidden?: boolean; // 是否隱藏
children?: ComfyUIPromptEditPanel[]; // group 型別的子節點
};
一些其他約定:
- 如果
seed
欄位為-1
,則會被替換為隨機數
如果您也希望建立自己的 ComfyUI 自定義頁面提供給自己的客戶,可以參考相關的前端程式碼。
最佳實踐
為了方便大家直觀體驗一下該解決方案成效,函式計算Serverless 應用中心上線基於 ComfyUI Serverless API 解決方案搭建的 應用-【少年白馬專屬】破次元壁合照 AI 繪畫平臺,作為一個實驗demo 開放體驗,期待為廣大開發者 AI 繪畫創業及變現提供一些有益思考。直接參加體驗活動,送好禮!
