每周，人们在ChatGPT Images和API中的GPT-Image模型上生成的图片超过30亿张。今天，我们扩展了ChatGPT Images 2.5的功能——这是我们最新的先进图像模型，为你的创意工作流带来更清晰的细节、更精确的编辑和更快的生成速度。
Images 2.5能呈现更自然的光照和更丰富的纹理，在保留参考照片中的主体方面表现更佳，并且能在多轮对话中更可靠地遵循编辑指令。与Images 2.0相比，我们还将图像生成延迟降低了最多50%，让你能更快地生成图像并完善构思。
在ChatGPT中，我们推出了多项产品功能，让你对创作过程拥有更多控制权。Sketch(在新窗口中打开)是一项新功能，让你可以直接在ChatGPT中绘图，作为最终图像的参考。模板功能让你能更轻松地开始创作一些最流行的图像格式，如传单和产品照片。你现在还可以直接在图像上添加评论，以实现更有针对性的编辑，并且可以分享你使用过的提示词，让其他人用他们自己的照片和细节来尝试你的创意。
Images 2.5现已面向所有ChatGPT、ChatGPT Work和Codex用户开放，支持桌面端、移动端和网页端。
对于开发者，我们在API中推出了两个新模型。GPT-Image-2.5 Flare在质量、编辑和速度方面带来了同样的改进，而GPT-Image-2.5 Sunburst则为精细创意工作提供了更高水平的精度，但生成时间更长。
创作过程中的图像保真度
最有意义的图像往往扎根于它们所基于的真实人物、地点和记忆。Images 2.5在利用参考照片将熟悉的主体转换到新场景、视觉风格和构图中时表现更佳。图像主体看起来更易辨认，光照和纹理感觉更自然，独特特征也更有可能得以保留。
对于使用API构建应用的团队，同样的保真度使以参考为导向的工作流更加可靠，因此变体可以始终锚定在原始来源上。
精确编辑
我们让你更容易进行有针对性的编辑，从而获得更符合你实际想法的最终图像。Images 2.5在只编辑你要求的内容方面表现更好，同时保持其余细节不变——即使面对更复杂的主体和背景也是如此。
对于使用Images API的开发者，这使用户能够更新单个元素（如产品、背景或文案），同时保留周围的主体、构图和品牌处理。
以下视频由多张图像组成，展示了模型在遵循精确编辑指令方面改进的能力。
多轮编辑一致性
在较长的ChatGPT对话中，Images 2.5能在多次编辑中更可靠地遵循特定编辑指令。较早的更改更有可能保持一致，每次新编辑都建立在已完成工作的基础上，而不会随时间推移降低图像质量。
这种一致性在生产工作流中也至关重要，因为开发者需要进行有针对性的更改，而无需重建整个素材。

智能与风格改进
Images 2.5在理解复杂视觉指令并将其转化为连贯结果方面表现更佳。包含现实世界信息的图像内容更准确，模型还能处理更复杂的布局，包括透明背景。它在反映视觉风格方面也更出色，因此你的图像更贴合你的艺术构想。
对于开发者和企业而言，这使得复杂的创意简报更加可靠。模型更有可能保留所要求的视觉方向、构图和细节，而不是随着指令变得更加具体而偏离方向。这在生成一系列符合品牌调性的创意素材、保持给定层级结构的UI概念，或适配特定结构的演示视觉时尤为重要。
使用Sketch将你的想法绘制成图
有时，解释一个想法最清晰的方式就是把它画出来。
我们推出了Sketch，这是一项新功能，让你可以直接在ChatGPT中绘图，并将其作为视觉指南。现在，你可以快速勾勒房间布局、构思中的服装轮廓，或者只是一个有趣的涂鸦，ChatGPT会将你的粗略画作转化为完整的图像。添加风格描述以及任何你希望确保能反映你构想的其他细节。
你不需要是专业艺术家——这只是另一种让最终图像更接近你想法的方式。要亲自尝试(在新窗口中打开)，只需在ChatGPT中输入“@Sketch”即可。
结构化你的提示词以获得更好结果
有时你可能对自己想创作的内容有清晰的想法——只是需要一些帮助来开始。
我们为一些最流行的创意格式推出了模板。无需从空白画布开始，你可以选择“海报”或“周边商品”等模板，并添加要传达的信息、设计元素或风格等细节来个性化你的结果。
分享你的最佳创意
通常，你会得到一张好到忍不住分享的图像。
现在，当你分享图像时，你还可以选择附上生成它的提示词。其他人随后可以沿用同样的创意，带入他们自己的图像和细节，制作出属于他们自己风格的版本。
API中的Images 2.5
开发者每天都在使用Images API，将图像生成工作流构建到创意、营销、零售和媒体团队使用的产品中。
我们在API中发布了两个新的图像模型：
GPT-Image-2.5 Flare 为API带来了质量、编辑和速度方面的同样改进，是大多数应用的默认选择，以降低50%的延迟提供比GPT-Image-2更高质量的图像。它非常适合从创作者和社交内容到产品体验、视觉搜索、快速图像原型制作以及大批量生成等各种场景。
GPT-Image-2.5 Sunburst 专为高端视觉工作流打造，这些工作流受益于编辑过程中更精细的控制。将其用于创意和编辑工作流，如可投入生产的活动创意或精致的产

定价与可用性
Images 2.5 今日起向 ChatGPT、ChatGPT Work 和 Codex 用户推出，覆盖所有层级，并支持桌面端、移动端和网页端。
Every week, people create more than 3 billion images across ChatGPT Images and the GPT‑Image models in the API. Today, we’re expanding what you can create with ChatGPT Images 2.5—our new state-of-the-art image model that brings sharper details, more precise editing, and faster generation to your creative workflows.
Images 2.5 produces more natural lighting and richer textures, is better at preserving the subjects in your reference photos, and follows editing instructions more reliably across multiple turns. We’ve also reduced image generation latency by up to 50% compared with Images 2.0, so you can generate images and refine your concepts more quickly.
In ChatGPT, we’re introducing product features that give you more control over the creative process. Sketch(opens in a new window) is a new feature that lets you draw directly in ChatGPT as a reference for your final image. Templates make it easier to start creating across some of the most popular image formats, like flyers and product photos. You can also now place comments directly on images for more focused editing, and you can share prompts you’ve used to let others try your ideas with their own photos and details.
Images 2.5 is available to all ChatGPT, ChatGPT Work, and Codex users across desktop, mobile, and web.
For developers, we’re introducing two new models in the API. GPT‑Image‑2.5 Flare brings the same improvements in quality, editing, and speed, and GPT‑Image‑2.5 Sunburst offers an extra level of precision for detailed creative work with longer generation times.
Image fidelity as you create
The most meaningful images feel grounded in the real-life people, places, and memories they’re based on. Images 2.5 is better at working from reference photos to transform familiar subjects across new settings, visual styles, and compositions. Image subjects look more recognizable, lighting and textures feel more natural, and distinctive features are more likely to carry through.
For teams building with the API, this same fidelity makes reference-led workflows more reliable, so variations can stay anchored to the original source.
Precision editing
We’ve made it easier for you to make focused edits, so you end up with final images that are more aligned with what you actually had in mind. Images 2.5 is better at editing only what you’ve asked for, while keeping the rest of the details the same—even with more complex subjects and backgrounds.
For developers using the Images API, this gives users the ability to update a single element—such as a product, background, or piece of copy—while preserving the subject, composition, and brand treatment around it.
The following videos are made up of multiple images, highlighting the model’s improved ability to follow precise editing instructions.
Multi-turn editing consistency
During longer ChatGPT conversations, Images 2.5 follows specific editing instructions more reliably across multiple edits. Earlier changes are more likely to stay consistent, and each new edit builds on the work you’ve already done without degrading image quality over time.
That consistency also matters in production workflows, where developers need to make targeted changes without rebuilding the entire asset.
The following videos are made up of multiple images, highlighting the model’s improved ability to maintain image quality over multiple turns.
Intelligence and style improvements
Images 2.5 is better at understanding complex visual instructions and translating them into coherent results. Images that include real-world information have more accurate content, and the model can handle more complex layouts including transparent backgrounds. It’s also better at reflecting visual styles, so your images are more aligned with your artistic vision.
For developers and businesses, this makes complex creative briefs more dependable. The model is more likely to retain the requested visual direction, composition, and individual details, instead of drifting as instructions become more specific. That matters when generating a series of on-brand creative assets, UI concepts that preserve a given hierarchy, or presentation visuals that fit a defined structure.
Use Sketch to draw your idea to life
Sometimes the clearest way to explain an idea is by drawing it.
We’re introducing Sketch, a new feature which lets you draw right in ChatGPT and use it as a visual guide. Now you can quickly sketch the layout of a room, the contour of an outfit you’re concepting, or just a funny doodle, and ChatGPT will turn your rough art into a complete image. Add a description of the style and any other details you want to make sure it reflects your vision.
You don’t need to be a professional artist—this is just another way to get your final image closer to what you have in mind. To try it yourself(opens in a new window), just type “@Sketch” in ChatGPT.
Structure your prompts for better results
At times you may have a clear idea of what you want to make—you just need some help getting started.
We’re introducing templates for some of the most popular creative formats. Instead of starting with a blank canvas, you can choose a template like “Poster” or “Merch” and add details like information to convey, design elements, or styles to personalize your results.
Pass your best ideas along
Often you end up with an image that’s too good not to share.
Now when you share an image, you can also choose to include the prompt that got you there. Someone else can then run with the same idea, bringing in their own images and details to make a version that feels like their own.
Images 2.5 in the API
Developers are building image generation workflows into products used by creative, marketing, retail, and media teams every day with the Images API.
We’re releasing two new image models in the API:
GPT‑Image‑2.5 Flare brings the same improvements in quality, editing, and speed to the API and is the default choice for most applications, delivering higher-quality images than GPT‑Image‑2 at 50% lower latency. It’s well suited to everything from creator and social content to product experiences, visual search, rapid image prototyping, and high-volume generation.
GPT‑Image‑2.5 Sunburst is built for premium visual workflows that benefit from tighter control across edits. Use it for creative and editing workflows like production-ready campaign creative or polished product imagery.
Here’s what early customers have to say about the new models:
