There are many types of AI large models available now. Based on their primary functions, I've simply divided them into a few major categories to help you choose according to your needs. Below are the categories and some recommendations that I find handy—easy to get started with and practical!

1. Text Generation: All-rounders for Writing, Chatting, and Polishing ​

These models specialize in text understanding and generation. Whether it's writing articles, translating, polishing copy, or just casual chatting, they can handle it.

  • Free & User-Friendly (China):

    • DeepSeek Chat (chat.deepseek.com): A versatile tool for text tasks, simple and easy to use.
    • Tencent Yuanbao (yuanbao.tencent.com): Feature-rich, handles daily text processing with ease.
    • Qwen (Tongyi Qianwen) (chat.qwen.ai): Reliable and stable, suitable for various text needs.

  • Worth Trying (International):

    • Grok (grok.com): Particularly good for tasks requiring real-time search, seamlessly integrates data from the X platform for top-notch information freshness.
    • Gemini (via Google AI Studio, aistudio.google.com): Almost free with no limits, excels at text generation, translation, and polishing, and can even handle mixed text and image layouts—just doesn't generate video.

2. Text-to-Image: Turn a Sentence into Art ​

These models can generate images directly from your text descriptions, a great helper for brainstorming.

  • Recommended (China):

    • Jimeng (Dreamina) (jimeng.jianying.com): Can generate images and videos, full of creativity, though the free quota is a bit limited.
    • Tongyi Wanxiang (wan.video): Excels at both images and videos with good results, but also has limited free usage.

  • Powerful International Options:

    • Grok: Not only good with text but also capable of image generation.
    • Gemini: Even more powerful; besides generating images independently, it can directly insert images into text, offering a super cool experience.

3. Text or Image to Video: From Idea to Short Clip ​

These models can turn text or images into short videos of a few seconds, perfect for those who want quick results.

4. Audio/Video Understanding: Listen, Watch, and Summarize ​

These models can analyze audio or video content and output text transcripts or summaries—extremely practical.

My Experience and Recommendations ​

The above are several large models I frequently use, and they've all performed quite well in my experience. For China, DeepSeek Chat, Tencent Yuanbao, and Qwen (Tongyi Qianwen) are solid and reliable for text tasks, and they're free and easy to use.

Internationally, Grok is particularly effective for searching information thanks to real-time data from the X platform; Gemini is an all-around powerhouse, almost free and incredibly powerful, especially impressive in mixed text and image layouts. For text-to-image or video generation, Jimeng (Dreamina) and Tongyi Wanxiang are good domestic choices, though you need to be mindful of their free quotas.

If you're too lazy to choose and just want one model, I highly recommend Gemini. Apart from not generating video, its other functions are nearly perfect, with ridiculously high value for money, and it's a joy for developers to use!
