ChainCatcher 消息,近日多名用户发现一个名为 luna-lisa-alpha 的图像模型出现在 LMArena 测试平台中,疑似 OpenAI 正在测试的新一代图像生成模型。虽未获官方确认,但外界猜测可能是 GPT Image 2.5 或下一代 GPT Image 的早期版本。

从测试反馈来看,新模型在角色一致性、图像真实感、文字生成能力噪点控制等方面均有明显提升。部分测试者将其与 GPT Image 2.0、Nano Banana Pro 和 Grok Imagine 等模型对比后认为,luna-lisa-alpha 在多轮生成中能更好地保持同一角色的外观、服饰和风格。但也有测试者指出,复杂纹理区域仍存在重复纹理问题。同日,OpenAI 宣布 GPT Image 2 API 预览支持透明背景生成,可用于产品图片、网页设计等场景。多个 checkpoint 名称的曝光也让社区猜测 OpenAI 或在进行 A/B 测试。该模型最终是否正式发布仍不确定,需等待 OpenAI 官方信息。
