Google 发布 Nano Banana 2：结合 Pro 能力与闪电速度的新一代图像模型
Google Releases Nano Banana 2: Next-Gen Image Model Combining Pro Capabilities with Lightning Speed
Google DeepMind 今日发布 Nano Banana 2（Gemini 3.1 Flash Image），这是继去年 Nano Banana 病毒式传播后的最新一代图像生成模型。该模型将 Nano Banana Pro 的高级功能与 Gemini Flash 的闪电速度相结合，让用户在保持专业级质量的同时实现快速编辑和迭代。
速度与智能的融合
Nano Banana 2 将 Gemini Flash 的高速智能带入视觉生成领域，使快速编辑和迭代成为可能。它将原本专属于 Pro 版本的功能带给更广泛的用户：
高级世界知识
模型利用 Gemini 的真实世界知识库，并通过实时网络搜索获取最新信息和图像，更准确地渲染特定主题。这种深度理解还能帮助用户创建信息图表、将笔记转换为图表以及生成数据可视化。
精确文本渲染与翻译
Nano Banana 2 允许生成准确、清晰可读的文本，适用于营销模型或贺卡。用户甚至可以在图像内翻译和本地化文本，与全球分享创意。
增强的创意控制
Nano Banana 2 大幅缩小了速度与视觉保真度之间的差距，提供高质量、逼真的图像：
- 主体一致性：在单个工作流中保持多达五个角色的外观一致，以及多达 14 个对象的保真度，让用户可以在不改变输入外观的情况下进行故事板创作和构建叙事。
- 精确指令遵循：通过增强的指令遵循能力，模型更严格地遵循复杂请求，捕捉创意的特定细微差别。
- 生产就绪规格：支持从 512px 到 4K 的各种宽高比和分辨率，确保视觉效果无论是用于垂直社交帖子还是宽屏背景都能保持清晰。
- 视觉保真度升级：提供生动的光照、更丰富的纹理和更锐利的细节，在 Flash 预期的速度下保持高质量美学。
多平台部署
Nano Banana 2 今日起在多个 Google 产品中推出：
- Gemini 应用：将替代 Fast、Thinking 和 Pro 模型中的 Nano Banana Pro。Pro 和 Ultra 订阅用户仍可通过三点菜单重新生成图像来使用 Pro 版本。
- Google 搜索：在 AI 模式和 Lens 中可用，支持 141 个新国家/地区和八种额外语言。
- AI Studio + API：在 AI Studio 和 Gemini API 中提供预览版。
- Google Cloud：在 Vertex AI 的 Gemini API 中提供预览版。
- Flow：作为 Flow 的新默认图像生成模型，所有 Flow 用户可免费使用。
- Google Ads：在创建广告系列时提供智能建议。

Google DeepMind today released Nano Banana 2 (Gemini 3.1 Flash Image), the latest generation of image generation model following last year's viral Nano Banana sensation. This model combines the advanced features of Nano Banana Pro with the lightning speed of Gemini Flash, enabling users to achieve rapid edits and iteration while maintaining professional-grade quality.
Fusion of Speed and Intelligence
Nano Banana 2 brings Gemini Flash's high-speed intelligence to visual generation, making rapid edits and iteration possible. It makes once-exclusive Pro features accessible to a wider audience:
Advanced World Knowledge
The model pulls from Gemini's real-world knowledge base and is powered by real-time web search to more accurately render specific subjects. This deep understanding also helps create infographics, turn notes into diagrams, and generate data visualizations.
Precision Text Rendering and Translation
Nano Banana 2 allows generation of accurate, legible text for marketing mockups or greeting cards. Users can even translate and localize text within an image to share ideas globally.
Enhanced Creative Control
Nano Banana 2 dramatically closes the gap between speed and visual fidelity, delivering high-quality, photorealistic imagery:
- Subject Consistency: Maintain character resemblance of up to five characters and fidelity of up to 14 objects in a single workflow, allowing storyboarding and narrative building without altering input appearance.
- Precise Instruction Following: With enhanced instruction following, the model adheres more strictly to complex requests, capturing specific nuances of ideas.
- Production-Ready Specs: Support various aspect ratios and resolutions from 512px to 4K, ensuring visuals stay sharp for vertical social posts or wide-screen backdrops.
- Visual Fidelity Upgrade: Delivers vibrant lighting, richer textures, and sharper details, maintaining high-quality aesthetics at Flash speed.
Multi-Platform Rollout
Nano Banana 2 is rolling out today across Google products:
- Gemini App: Replaces Nano Banana Pro across Fast, Thinking, and Pro models. Pro and Ultra subscribers retain access to Pro version via three-dot menu regeneration.
- Google Search: Available in AI Mode and Lens, supporting 141 new countries/territories and eight additional languages.
- AI Studio + API: Available in preview in AI Studio and Gemini API.
- Google Cloud: Available in preview with Gemini API in Vertex AI.
- Flow: New default image generation model, available to all Flow users at zero credits.
- Google Ads: Powers suggestions while creating campaigns.
Content Provenance and Verification
Google continues deepening its provenance approach by coupling SynthID technology with C2PA Content Credentials to help identify and verify AI-generated content.
