AI tools iterate so fast that recommendations from three months ago may already be out of date. This list covers 14 high-frequency scenarios — knowledge Q&A, coding, image design, video generation, music creation, and more — and for each scenario it lists the best international and Chinese options side by side. If you want to spend the May Day holiday on an intensive tour of AI tools, you can use this list directly as a buying guide.

Knowledge Q&A

• International: GPT-5.5 -- the best hallucination control of the bunch, ideal for knowledge queries that demand high accuracy
• Chinese: Doubao -- a generous free tier, plenty for everyday Q&A

Content Creation and Knowledge Management

• International: Claude Opus 4.6 -- in a league of its own for long-form writing and content organization
• Chinese: DeepSeek V4 Pro -- consistently strong Chinese content creation

Data Analysis

• International: Codex + GPT-5.5 -- data cleaning, statistical analysis, and visualization in one stop
• Chinese: Claude Code + GLM-5.1 -- used as a combo: Claude Code plans, GLM-5.1 executes

Frontend Design

• International: Gemini 3.1 Pro -- a strong grasp of UI components and layout
• Chinese: Kimi K2.6 -- reliably good frontend code generation

Architecture Planning

• International: Claude Code + Claude Opus 4.7 -- use Opus for the overall architecture design first, then refine it with Code
• Chinese: Claude Code + GLM-5.1 -- the same plan-plus-execute combination

Code Development and Execution

• International: Codex + GPT-5.5 -- fast execution, high code quality
• Chinese: Claude Code + GLM-5.1

Recommended workflow: use Claude Code + Opus 4.7 to finish planning and architecture design first, then move to Codex + GPT-5.5 for detailed development and execution.

Deep Research

• International: ChatGPT DeepResearch -- automated searching, analysis, and research report writing
• Chinese: Doubao -- offers the same deep search and analysis capabilities

Images and Graphic Design

• International: GPT-image-2 -- in a league of its own for text rendering, typography, and infographics
• Chinese: Jimeng Seedream-5.0-lite -- solid image generation quality, and its Chinese text rendering is catching up fast

Video Generation and Editing

• Seedance 2.0 -- excellent motion quality, with fluid, natural human movement
• Kling 3.0 -- cinematic texture, with native 4K output

Both are Chinese products; in the video generation race, Chinese options are already out in front.

Music Generation

• International: Suno v5.5
• Chinese: MiniMax Music 2.6

3D Generation

• TripoAI -- currently the most polished product in 3D asset generation

AI Keyboards

• Doubao Input Method -- extremely accurate speech recognition, with standout performance in mixed Chinese-English scenarios

AI Hardware

• Feishu Recording Bean -- automatically turns each day's voice conversations into Feishu meeting notes
• GetSeed Recording Card -- organizes your recorded audio automatically every day, helping you build a personal knowledge base

How to Choose

There is only one core principle for picking tools: define the scenario first, then choose the tool, and compare prices last.

1. If you are an individual user, start with the free Chinese options (Doubao, DeepSeek, Jimeng)
2. If you need professional-grade output (design, video, research reports), paid international tools have the higher ceiling
3. For coding, the recommended combo workflow is "Claude Code for planning + Codex for execution," balancing quality and speed
4. For video generation you don't need to look abroad — Seedance 2.0 and Kling 3.0 are already the strongest options available right now
