Gemini 也提供了图像生成能力，作为一种替代方案。与 Imagen 3.0 相比，Gemini 的图像生成更适合于需要上下文理解和推理的场景，而非追求极致的艺术表现和视觉质量。

更高的视觉质量 → 相比 exp 版，图像更锐利、更丰富、更清晰。
更准确的文本呈现 → 生成的视觉中，文本更加精准、干净、易读。
显著减少过滤拦截 → 得益于更智能、宽松的过滤机制，创作时几乎不再被打断。
说明：

模型 id：gemini-2.0-flash-preview-image-generation
费率（输入→输出）：
0.1
→
0.1→0.4/M tokens
需要新增参数来体验新特性 "modalities":["text","image"]
图片以 Base64 编码形式传递与输出
作为实验模型，建议明确指出 “输出图片”，否则可能只有文本
输出图片的默认高度为 1024px
python 调用需要最新的 openai sdk 支持，请先运行 pip install -U openai

Render the figure in a detailed, lifelike style and environment, placed on a shelf inside an ultra-realistic figure display cabinet, mounted on a circular transparent acrylic base without any text. Maintain highly precise details in texture, material, and paintwork to enhance realism. The cabinet scene should feature a natural depth of field with a smooth transition between foreground and background for a realistic photographic look. Lighting should appear natural and adaptive to the scene, automatically adjusting based on the overall composition instead of being locked to a specific direction, simulating the quality and reflection of real commercial photography. Other shelves in the cabinet should contain different figures which are slightly blurred due to being out of focus, enhancing spatial realism and depth"
