Google Launches Gemini Nano Banana 2.1 Image Model with Pricing and Deprecation of Predecessor
多模态低延迟
EVENT SUMMARY
事件摘要
Google 正式 GA 发布 Gemini Nano Banana 2.1 (gemini-nano-banana-2.1) 图像生成与编辑模型，替代前代 gemini-3.1-flash-image (Nano Banana 2，将于10月29日关闭)。新模型在视觉质量、多轮角色一致性及文本渲染上显著提升，支持 1K 至 4K 分辨率及宽幅比例，并支持 Google Search Grounding（每月5000次免费）。定价方面，Standard 模式图像输出 $30/百万 tokens，Batch 模式半价；该模型不提供 Free Tier，仅限付费层使用。
ANALYST VIEW
中立分析
为什么重要
Gemini 在图像生成领域推出效率导向的新模型，直接对标 DALL-E、Midjourney 等产品。搜索增强生成是其差异化特性，旧模型的快速迭代下线反映了激进的更新节奏。
影响对象
面向需要批量或实时图像生成的开发者与企业用户。当前使用旧版模型的开发者需在 10 月 29 日前完成迁移；无免费层提高了个人开发者的试用门槛。
证据说明
Google 官方发布说明、API 更新日志及定价页面直接证实了模型 GA 状态、核心能力、定价细节及旧版弃用时间表。
不确定性
具体延迟指标、与其他图像生成服务的画质/成本综合对比尚未有第三方验证；23 天的迁移窗口对部分企业可能较为紧张。
