Hmm, the user is asking for a简介 of HiDream.ai. Let me summarize what I've found from all these search results.

First, I notice that HiDream.ai is an AI startup founded in 2023 by Mei Tao, who's quite a big deal - he's a former VP at JD.com and a foreign member of the Canadian Academy of Engineering. The company is called Zhixiang Weilai in Chinese.

The core thing here is their multimodal AI platform that works with text, images, videos, and 3D models. They've developed this "Pixeling" model that's apparently quite powerful - it has over 13 billion parameters and can handle conversions between all four modalities. That's pretty impressive technically.

Looking at their features, they offer a wide range: text-to-image, image-to-video, video style transfer, 3D model generation, and lots of editing tools like inpainting, outpainting, and upscaling. It seems aimed at both professionals and casual users.

I see they've got different pricing tiers with free credits for new users. Their paid plans range from basic membership to max membership with different capabilities. The applications span design, e-commerce, gaming, and marketing - quite versatile.

The company has been doing well financially too - they've raised nearly 100 million RMB in two funding rounds, with investors like iFlytek's venture fund. Their tech is competitive globally, with their image generation model outperforming Midjourney v5 and DALL-E 3 on some benchmarks.

The user didn't specify how detailed they want this, so I'll give a comprehensive overview covering the company background, tech capabilities, features, applications, and business status. I'll organize it clearly with sections but keep it concise enough for a quick read.
