Image2 vs Flare vs Sunburst：同 prompt 速度與成片對打

提示詞

GPT Image 2 vs GPT Image 2.5 Flare vs GPT Image 2.5 Sunburst:

We ran the same prompts through all three models to see what the 2.5 upgrade actually changes.

Here are the results.

Speed:

Flare is the fastest by a wide margin. It finished about 2.3x faster than GPT Image 2 and about 1.8x faster than Sunburst. Sunburst was still around 1.3x faster than GPT Image 2.

Image quality:

Sunburst came out on top, with more natural lighting and slightly fewer AI hallucinations. Flare's quality is close to GPT Image 2, with a big speed advantage.

Editing:

Editing is where 2.5 is supposed to improve the most, so we gave each model the same image and asked for several edits in a row. All three models handled the first edits well and kept the rest of the image consistent.

The differences showed up in the final edit:

• GPT Image 2 had a clear placement error.
• Flare had a small blending issue.
• Sunburst got everything right.

Pricing:

Both 2.5 models cost the same per token as GPT Image 2.

Which one to use:
• Flare for fast results and lots of variations.

• Sunburst for the best lighting and for images that need several rounds of edits.

中文翻譯

GPT Image 2 vs GPT Image 2.5 Flare vs GPT Image 2.5 Sunburst：

我們用相同的 prompt 跑遍了這三個模型，看看 2.5 升級到底改變了什麼。

以下是結果。

速度：

Flare 明顯最快。它的完成速度約爲 GPT Image 2 的 2.3 倍，約爲 Sunburst 的 1.8 倍。Sunburst 仍比 GPT Image 2 快約 1.3 倍。

圖像質量：

Sunburst 位居第一，光線更自然，AI 幻覺也略少一些。Flare 的質量接近 GPT Image 2，但速度優勢明顯。

編輯：

編輯本應是 2.5 改進最大的地方，所以我們給每個模型同一張圖，並要求連續進行多次編輯。三個模型都很好地處理了最初的編輯，並保持畫面其餘部分一致。

差異出現在最後一次編輯：

• GPT Image 2 出現了明顯的放置錯誤。
• Flare 有輕微的融合問題。
• Sunburst 把一切都處理正確了。

定價：

兩個 2.5 模型的每 token 價格都與 GPT Image 2 相同。

該用哪一個：
• Flare 適合快速出結果和大量變體。

• Sunburst 適合追求最佳光線以及需要多輪編輯的圖像。
