DALL-E-3发送的大小参数有误

[naizhao]

DALL-E-3模型只支持下面的大小，但对话中发送的大小是512

openai error: '512x512' is not one of ['1024x1024', '1792x1024', '1024x1792'] - 'size'

Must be one of 256x256, 512x512, or 1024x1024 for dall-e-2.
Must be one of 1024x1024, 1792x1024, or 1024x1792 for dall-e-3 models.

Title: DALL-E-3 The size parameter sent is wrong

未能复现问题，请检查你的上游是否为标准的 OpenAI API 格式提供的 DALL-E-3 模型

If the problem cannot be reproduced, please check whether your upstream provides the DALL-E-3 model in the standard OpenAI API format.

开源版判断逻辑的实现是这样的：

coai/adapter/openai/image.go

Lines 29 to 33 in eb44490

	Size: utils.Multi[ImageSize](
	props.Model == globals.Dalle3,
	ImageSize1024,
	ImageSize512,
	),

判断为 model == dall-e-3 后即返回 1024x1024 size。
可能造成的原因：模型名非官方名称 dall-e-3；模型名增加前/后缀。

The implementation of the open source version’s judgment logic is as follows:

coai/adapter/openai/image.go

Lines 29 to 33 in eb44490

	Size: utils.Multi[ImageSize](
	props.Model == globals.Dalle3,
	ImageSize1024,
	ImageSize512,
	),

After it is determined that model == dall-e-3, 1024x1024 size is returned.
Possible reasons: The model name is unofficial name dall-e-3; a suffix is ​​added to the model name.
