Image2 vs Flare vs Sunburst：同 prompt 速度与成片对打

提示词

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.

中文译文

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

我们用相同的 prompt 跑遍了这三个模型，看看 2.5 升级到底改变了什么。

以下是结果。

速度：

Flare 明显最快。它的完成速度约为 GPT Image 2 的 2.3 倍，约为 Sunburst 的 1.8 倍。Sunburst 仍比 GPT Image 2 快约 1.3 倍。

图像质量：

Sunburst 位居第一，光线更自然，AI 幻觉也略少一些。Flare 的质量接近 GPT Image 2，但速度优势明显。

编辑：

编辑本应是 2.5 改进最大的地方，所以我们给每个模型同一张图，并要求连续进行多次编辑。三个模型都很好地处理了最初的编辑，并保持画面其余部分一致。

差异出现在最后一次编辑：

• GPT Image 2 出现了明显的放置错误。
• Flare 有轻微的融合问题。
• Sunburst 把一切都处理正确了。

定价：

两个 2.5 模型的每 token 价格都与 GPT Image 2 相同。

该用哪一个：
• Flare 适合快速出结果和大量变体。

• Sunburst 适合追求最佳光线以及需要多轮编辑的图像。
