Somewhere along the way, writing code stopped being just about writing code. Now you’re also managing AI tools that write code for you, debug it, explain it, and occasionally make you question your own competence.

And right in the middle of this chaos, two names keep coming up:

• DeepSeek 编码器 V2
• Gemini Code Assist

Both are powerful. Both are evolving fast. And both are trying very hard to become your default coding partner.

So instead of vague claims and “AI will change everything” speeches, let’s break down how these tools actually compare in real-world development scenarios.
