Google 已在美国发布其 AI 文本转图像生成器 Imagen 3 的最新版本。该工具旨在生成比 Google 之前模型更详细、光线更丰富且更少干扰伪影的图像。Imagen 3 可以根据你的提示创建详细的图像，你还可以通过突出显示特定部分并描述你想要更改的内容来编辑图像。

🚀 Imagen 3 是 Google 发布的最新 AI 图像生成器，旨在生成更逼真、更详细的图像，并减少干扰伪影。

🎨 Imagen 3 可以根据用户的文本描述生成图像，并支持对图像进行编辑，例如突出显示特定部分并描述想要更改的内容。

🛡️ Imagen 3 设有一些安全措施，例如拒绝生成公众人物（如 Taylor Swift）的图像以及武器图像。尽管它不会生成具有版权的命名角色，但用户可以通过描述想要创建的角色来绕过此限制。

⚠️ Google 之前曾因 Gemini AI 聊天机器人生成历史不准确的图像而停止让人们使用它来生成图像。

💡 Imagen 3 与 Elon Musk 的 X 平台上的 AI 图像生成器 Grok 形成鲜明对比，Grok 被用来生成各种奇异内容，包括包含毒品、暴力和公众人物做可疑事情的图像。

Google has released the latest version of Imagen 3, its AI text-to-image generator, to users in the US, as spotted by VentureBeat. The tool, which you can access on Google’s AI Test Kitchen, is supposed to generate images with “better detail, richer lighting, and fewer distracting artifacts” compared to Google’s previous models.

Google first announced its updated Imagen 3 tool during I/O in May, but it only appears to have made the tool generally available through its Vertex AI platform within the past several days. Some Reddit users started experimenting with Imagen 3 last week, and Google published a research paper on the tool on Tuesday.

Like other AI image generators, Imagen 3 can create detailed images based on your prompt. You can also edit the image by highlighting a certain part and describing what you want to change.

There seem to be some guardrails in place, as the tool will decline to generate images of public figures, like Taylor Swift, and also won’t produce images of weapons. And while it will stop short of generating named copyrighted characters, you can get around this pretty easily by describing the character you want to create.

I got the tool to generate images that look very much like Sonic the Hedgehog and Mario, while my colleague was able to create characters resembling Mickey Mouse. I also found that it will generate logos belonging to companies like Apple, Macy’s, Hershey’s, and even Google, which you can see in the image at the top of this article.

Despite these somewhat flexible guardrails, Imagen 3 still stands in stark contrast to Grok, the AI image generator that lives on Elon Musk’s X platform. Grok has been used to generate all sorts of wild content, including images with drugs, violence, and public figures doing questionable things.

But Google’s AI tools have run into some issues as well. Earlier this year, Google stopped letting people generate images with its Gemini AI chatbot after users found that it created historically inaccurate images.
