										<content:encoded><![CDATA[<p class="wp-block-paragraph">视觉人工智能实验室 Black Forest Labs 于当地时间 10 月 15 日以开放权重的形式发布了 FLUX 3 Image Klein 图像生成模型。这款模型拥有 56 亿（5.6B）参数，专门针对消费级 GPU 进行优化，主打让普通显卡也能跑起高质量图像生成。</p>
<h2 class="wp-block-heading">8GB 显存即可运行</h2>
<p class="wp-block-paragraph">FLUX 3 Image Klein 的显存门槛被压得很低：其 BF16 精度权重需要 12.2GB 内存，FP8 精度权重需要 5.6GB 内存；而精简后的 INT8 版本可通过 ComfyUI 或 Diffusers 框架，在仅配备 8GB 显存的英伟达 GeForce RTX 显卡上运行。</p>
<figure data-wp-context="{&quot;imageId&quot;:&quot;6af10d284de72&quot;}" data-wp-interactive="core/image" data-wp-key="6af10d284de72" class="wp-block-image wp-lightbox-container"><img decoding="async" data-wp-class--hide="state.isContentHidden" data-wp-class--show="state.isContentVisible" data-wp-init="callbacks.setButtonStyles" data-wp-on--click="actions.showLightbox" data-wp-on--load="callbacks.setButtonStyles" data-wp-on--pointerdown="actions.preloadImage" data-wp-on--pointerenter="actions.preloadImageWithDelay" data-wp-on--pointerleave="actions.cancelPreload" data-wp-on-window--resize="callbacks.setButtonStyles" src="https://mylogs.cn/wp-content/uploads/2026/10/inline_ad3025900666c6aa6ac35f533ab5a6f6_0.webp" alt="FLUX 3 Image Klein 模型示意图" title="图片来源：IT之家" style="max-width:100%;height:auto;"/><button

<h2 class="wp-block-heading">生成速度实测</h2>
<p class="wp-block-paragraph">根据测试数据，INT8 版本在 GeForce RTX 5090 上生成 100 万像素（1MP）图像大约需要 4 秒；在 GeForce RTX 4070 上通过 ComfyUI 生成同样分辨率的图片不到 9 秒。对于没有顶级显卡的普通用户，这意味着本地部署文生图工具的门槛大幅降低。</p>
<h2 class="wp-block-heading">能力与定位</h2>
<p class="wp-block-paragraph">FLUX 3 Image Klein 支持文本转图像、图像编辑与多参考生成，并原生支持 4K 分辨率，可实现像素级精确编辑和稳定的图案限位表现。Black Forest Labs 称该模型在多个场景下表现优于尺寸更大的开源模型，在速度与质量的平衡上更具优势。</p>

<p class="wp-block-paragraph">对预算有限的 AI 绘画爱好者与本地部署玩家而言，一个能在 8GB 显存显卡上流畅运行、又保持不错画质的开放权重模型，提供了比云端订阅更可控的选择；不过其具体画质上限与更大参数模型之间仍存在差距，适合对硬件敏感、追求性价比的用户群体。</p>]]></content:encoded>

					<description><![CDATA[OpenAI 于 2026 年 9 月 9 日正式发布 ChatGPT Images 2.5，将其定位为当前最 [&#8230;]]]></description>
										<content:encoded><![CDATA[
<p class="wp-block-paragraph"><a href="https://mylogs.cn/chatgpt-pro-%e9%87%8d%e5%bc%80-200-%e7%be%8e%e5%85%83%e6%a1%a3%ef%bc%9aapi-%e4%bb%b7%e5%80%bc%e8%bf%91%e7%bf%bb%e5%80%8d/">OpenAI</a> 于 2026 年 9 月 9 日正式发布 ChatGPT Images 2.5，将其定位为当前最先进的图像生成模型。新版本在图像生成延迟、细节表现与编辑可控性上均有明显升级，并新增 Sketch 草图参考、模板库和图片内评论标注等功能。</p>



<h2 class="wp-block-heading">生成速度更快，画质细节更稳</h2>



<p class="wp-block-paragraph">与 2026 年 4 月推出的 Images 2 相比，Images 2.5 的图像生成延迟最多可降低 50%。在速度提升的同时，新版本在细节锐度、自然光照和纹理丰富度方面也有改进。多轮编辑场景下，模型对先前修改的记忆更稳定，连续调整时不易出现细节退化或风格漂移。</p>



<p class="wp-block-paragraph">OpenAI 表示，ChatGPT 与 GPT-Image API 上的用户每周已生成超过 30 亿张图像，Images 2.5 的上线意味着这部分高频创作场景将获得更快的响应和更一致的输出。</p>



<h2 class="wp-block-heading">Sketch 草图：随手画几笔就能出图</h2>



<p class="wp-block-paragraph">Images 2.5 最大的亮点之一是 Sketch 功能。用户只需在 ChatGPT 输入框中调用 &#8220;@Sketch&#8221;，即可在对话中直接手绘草图，再补充风格与细节描述，模型会据此生成完整图像。这一功能降低了图像创作的门槛，用户无需用文字精确描述画面，也能表达创意意图。</p>



<p class="wp-block-paragraph">此外，新版本支持在图片上直接添加评论标注，圈选具体区域后发出修改指令，例如&#8221;将这里改为蓝色&#8221;或&#8221;删除此区域&#8221;，模型仅针对标注位置进行调整，其余部分保持不变。</p>



<h2 class="wp-block-heading">模板库与分享机制</h2>



<p class="wp-block-paragraph">为简化常见创作流程，Images 2.5 还新增了海报、商品图等模板库，用户可直接套用模板并填充内容。生成图像时，用户还能选择附带原始提示词分享，方便他人基于同一创意进行二次修改。</p>



<h2 class="wp-block-heading">面向开发者的两款 API 模型</h2>



<p class="wp-block-paragraph">在 API 侧，OpenAI 提供两种模型选择：</p>



<p class="wp-block-paragraph">&#8211; <strong>GPT-Image-2.5 Flare</strong>：适合创作者内容、社交素材、产品原型、视觉搜索和高批量生成等大多数场景。<br />&#8211; <strong>GPT-Image-2.5 Sunburst</strong>：面向对编辑控制要求更高的工作流，例如成品级营销素材和精修产品图，生成时间相对更长。</p>



<p class="wp-block-paragraph">API 支持 1024×1024、2048×2048、3840×2160 等多种分辨率，单边最长不超过 3840 像素，总像素数需在 655,360 至 8,294,400 之间。</p>



<h2 class="wp-block-heading">安全与可追溯</h2>



<p class="wp-block-paragraph">Images 2.5 延续现有的提示词与生成内容检查机制，所有输出均嵌入 C2PA 元数据和隐形水印，便于识别由 OpenAI 工具生成的图像。</p>



<p class="wp-block-paragraph">目前，ChatGPT Images 2.5 已向 ChatGPT、ChatGPT Work 和 Codex 用户开放，覆盖桌面端、移动端与网页端。</p>
