Midjourney发布了其近一年来的首个新AI图像生成模型V7。该模型在文本提示理解、图像质量和细节呈现方面均有显著提升。用户在使用前需建立个性化配置文件,以优化模型表现。V7提供Turbo和Relax两种模式,并引入Draft Mode以提升生成速度和降低成本。虽然部分功能尚未完全推出,但Midjourney强调V7在图像生成方面的独特优势,并鼓励用户积极尝试和反馈。Midjourney由David Holz于2022年创立,至今未接受外部融资,预计2023年收入约2亿美元,并成立硬件团队。

⚡️ V7提供了Turbo和Relax两种模式,前者运行成本较高,后者则更经济实惠。此外,新推出的Draft Mode能够以10倍的速度和一半的成本生成草图图像,方便用户快速预览和迭代。

🛠️ 虽然V7目前尚未完全支持所有功能,如图像放大和纹理重塑,但Midjourney计划在未来几个月内陆续推出。Midjourney鼓励用户积极尝试,并根据体验反馈优化模型。

Midjourney, one of the earliest AI image-generating services on the web, has released its first new AI image model in nearly a year.

Dubbed V7, the model, which began rolling out in alpha around midnight Eastern on Friday, comes a week after OpenAI debuted a new image generator in ChatGPT that quickly went viral for its ability to create Ghibli-style photos. Midjourney’s is not a Ghibli-optimized model — at least not officially — but nonetheless generates aesthetically pleasing works, at least to this reporter’s dilettante eye.

To use it, you’ll first have to rate around 200 images to build a Midjourney “personalization” profile if you haven’t already. This profile tunes the model to your individual visual preferences; V7 is Midjourney’s first to have personalization switched on by default.

Once you’ve completed that task, you’ll be greeted with a togglable V7 on Midjourney’s website and, if you’re a member of Midjourney’s Discord server, on its Discord chatbot. In the web app, you can quickly select the model from the drop-down menu next to the “version” label.

Midjourney CEO David Holz described V7 as a “totally different architecture” in a post on X.

“V7 is […] much smarter with text prompts,” Holz continued in an announcement on Discord. “[I]mage prompts look fantastic, image quality is noticeably higher with beautiful textures, and bodies, hands, and objects of all kinds have significantly better coherence on all details.”

V7 is available in two flavors, Turbo and Relax — the former of which is more costly to run — and powers a new tool called Draft Mode that renders images at 10x the speed and half the cost of the standard mode. Draft images are lower-quality than standard-mode images, but can be enhanced and re-rendered with a click of the mouse.

A number of Midjourney capabilities aren’t available yet for V7, according to Holz, including image upscaling and retexturing. Those will arrive in the near future, he said — possibly as soon as within two months.

“This is an entirely new model with unique strengths and probably a few weaknesses” Holz wrote on Discord. “[W]e want to learn from you what it’s good and bad at, but definitely keep in mind it may require different styles of prompting. So play around a bit.”

In my brief testing, V7 adhered reasonably well to the prompts I gave it. Granted, I didn’t have time to really put the model through the ringer.

Midjourney is an unusual operation. Started in 2022 by Holz, who co-founded PC peripheral company Leap Motion, it hasn’t taken a dime of outside money.

In late 2023, Midjourney was reportedly expecting to bring in around $200 million in revenue. Recently, the San Francisco-based firm said that it was establishing a hardware team to work on undisclosed projects, and it continues to train previously announced models for video and 3D object generation.

Several lawsuits accuse Midjourney of infringing on the rights of millions of artists by training AI tools on images scraped from the web without the consent of the images’ creators.
