GPT Image 2 API 收費點計?OpenAI 列出嘅價錢同估算方法

OpenAI 價格頁片段列明 GPT image 2 的 Inputs 為 $8.00、Cached inputs 為 $2.00;現有證據未能核實一個全包「每張圖」價錢。[2] 如果只係用一個 prompt 生成或編輯單張圖片,OpenAI 文件話 Image API 係最佳選擇。[14] Responses API 可以把圖像生成放入對話流程;但文件亦指該工具有自己嘅 GPT Image 模型選擇,所以套用 GPT Image 2 收費前要先確認實際模型係 gpt image 2。[12][15]

Create a landscape editorial hero image for this Studio Global article: GPT Image 2 Pricing: What OpenAI Lists and How to Estimate API Usage. Article summary: OpenAI’s pricing page lists GPT image 2 with $8.00 for inputs and $2.00 for cached inputs, but the supplied evidence does not support a simple flat per image price.[2].

如果你要為產品文件、客戶支援頁面,或者內部成本預算寫 GPT Image 2 API 收費,最穩陣嘅講法其實好窄:OpenAI 公開價格資料中,GPT-image-2 顯示 Inputs$8.00

Cached inputs
$2.00[2]

OpenAI 圖像生成文件亦說明,GPT Image 模型可以透過 image generation endpoint 使用,亦可以透過 Responses API 入面嘅 image generation tool 使用。[12][15]

要留意:目前提供嘅證據 未能核實 GPT Image 2 有一個簡單、全包嘅「每生成一張圖收 $X」價錢。[2] 所以,唔應該只見到兩個價格欄位,就直接推導成每張圖固定單價。

官方可核實嘅 GPT Image 2 價格欄位

OpenAI 價格頁片段將 GPT-image-2 描述為圖像生成模型,並顯示以下兩個價格欄位。[2]

OpenAI 顯示嘅價格欄位列出金額可以支持嘅講法
Inputs$8.00OpenAI 價格頁片段為 GPT-image-2 列出呢個 input 價格欄位。[2]
Cached inputs$2.00OpenAI 價格頁片段為 GPT-image-2 列出呢個 cached-input 價格欄位。[2]

呢個係目前最安全、最有來源支持嘅收費描述。相同片段未提供足夠上下文,去發布完整生成圖片總成本,亦未核實固定每圖報價。[2]

可唔可以話 GPT Image 2 係每張圖固定收費?

按現有證據,唔可以。OpenAI 價格頁片段顯示 GPT-image-2 有 input 同 cached-input 欄位,但提供嘅材料入面,未有完整每張圖計算方式。[2]

呢個分別好重要。你如果寫產品文件、對客收費說明,或者內部成本預測,可以引用 OpenAI 價格頁顯示嘅兩個欄位;但如果要將呢啲欄位變成用量估算,就應該先核對 OpenAI 即時價格頁面嘅計費單位,以及你個應用實際用緊邊條 API 路徑。[1][2]

去邊度估算 GPT Image 2 用量成本?

做估算時,先用 OpenAI API Pricing page 作為價格參考,再對返你個應用實際係點樣調用圖像生成。[1][2]

一個實用流程係:

  1. 喺 OpenAI 價格頁搵 GPT-image-2 目前可見片段列出 Inputs $8.00、Cached inputs $2.00[2]
  2. 確認 API path。 OpenAI 文件話,圖像生成可以經 image generation endpoint 做,亦可以經 Responses API 入面嘅 image generation tool 做。[12][15]
  3. 如果只係單一 prompt 生成或編輯一張圖,優先睇 Image API。 OpenAI 文件話,如果你只需要由一個 prompt 生成或編輯單張圖片,Image API 係最佳選擇。[14]
  4. 如果用 Responses API,要核對模型選擇。 OpenAI 話 Responses API image generation tool 有自己嘅 GPT Image model selection;套用 GPT Image 2 收費假設前,要先確認實際選用模型係 gpt-image-2[12]
  5. 最後按 live pricing page 顯示嘅計費單位計數。 現有證據支持嘅係可見 input 同 cached-input 欄位,而唔係完整固定每圖總價。[1][2]

開發團隊 endpoint 檢查表

OpenAI 圖像生成文件話,API 可以用 GPT Image 或 DALL·E 模型,根據文字 prompt 生成同編輯圖片。[14][15] 對於 GPT Image 2,文件標示 gpt-image-2 係最新 GPT Image 模型;OpenAI 亦有獨立 GPT Image 2 模型文件頁。[12][22]

如果你個 app 係咁做應該檢查嘅 OpenAI API 路徑點解會影響估算
由一個 prompt 生成或編輯一張圖片Image APIOpenAI 文件話,單一 prompt、單張圖嘅情況,Image API 係最佳選擇。[14]
喺對話流程入面生成圖片Responses API image generation toolOpenAI 話呢個工具可以作為對話一部分生成圖片,而且有自己嘅 GPT Image 模型選擇。[12][15]

文件或客服可以點樣安全表述?

可以用以下講法,將已核實價格欄位同最終估算分開:

OpenAI 的 API Pricing page 將 GPT-image-2 列為 Inputs $8.00、Cached inputs $2.00。最終用量估算應以 OpenAI 即時價格頁為準,並在確認應用程式實際使用嘅 endpoint、模型選擇及計費單位後再計算。[1][2][12]

一句到尾

可核實嘅成本講法係:OpenAI 價格頁列出 GPT-image-2 的 Inputs $8.00、Cached inputs $2.00[2] 真正做用量規劃時,就要先睇 OpenAI API Pricing page,再確認產品用緊 Image API,定係 Responses API image generation tool,之後先好發布最終估算。[1][12][15]

重點

  • OpenAI 價格頁片段列明 GPT image 2 的 Inputs 為 $8.00、Cached inputs 為 $2.00;現有證據未能核實一個全包「每張圖」價錢。[2]
  • 如果只係用一個 prompt 生成或編輯單張圖片,OpenAI 文件話 Image API 係最佳選擇。[14]
  • Responses API 可以把圖像生成放入對話流程;但文件亦指該工具有自己嘅 GPT Image 模型選擇,所以套用 GPT Image 2 收費前要先確認實際模型係 gpt image 2。[12][15]

Search and fact-check: How much does GPT Image 2 cost, and where do I estimate usage pricing?

Studio Global AI29 來源

引用的答案

I can confirm where to look, but I can’t verify an exact GPT Image 2 price from the evidence provided. The supplied evidence points to OpenAI’s API Pricing page for estimating costs, while the image generation docs identify gpt-image-2 as the latest GPT Image model and show that it can be used through the image generation endpoint or the Responses API image generation tool.[1][3][6]

What’s supported by the evidence

  • gpt-image-2 is described in OpenAI’s docs as the latest GPT Image model.[3][4]
  • OpenAI’s image generation guide says you can use GPT Image models through the image generation endpoint, and it also mentions the image generation tool in the Responses API.[3][6]
  • OpenAI has a dedicated GPT Image 2 model documentation page.[2]
  • OpenAI also has a central API Pricing page, which is the place indicated by the evidence for pricing reference and usage-cost estimation.[1]

What I could not verify

  • Insufficient evidence to state the exact cost of GPT Image 2 from the material provided.[1][2]
  • The provided pricing snippet shows prices for other models, but it does not include a visible gpt-image-2 line item or a clear per-image/per-token rate for GPT Image 2.[1]

Answer to your question

  • How much does GPT Image 2 cost?
    I don’t know from the provided evidence; there is not enough visible pricing data here to fact-check an exact amount for GPT Image 2.[1][2]

  • Where do I estimate usage pricing?
    Use the OpenAI API Pricing page for pricing reference and estimation.[1]
