I Didn't Want to Write This
I really didn't. Another AI coding tool comparison? Please. But after three weeks of forcing myself to use both Baichuan and Cursor side by side on real projects—not just toy examples—I have opinions. Strong ones.
Let me tell you what happened when I tried to build a React dashboard with live WebSocket data.
First Encounter: Baichuan
Baichuan felt like talking to a patient professor. I typed "build me a real-time chart component that updates every second." It paused. Then it generated the entire file—imports, state management, cleanup logic, error boundaries. No hand-holding. It assumed I knew what I was doing.
The code was clean. TypeScript types everywhere. Comments in Chinese and English mixed. Weird, but I got used to it.
But when I asked it to refactor the same component into custom hooks, it hesitated. It kept suggesting I restructure the whole app instead. Like a stubborn senior dev who thinks they know better.
Then Cursor
Cursor is the opposite. It's the eager intern who finishes your sentences. I opened a new file, started typing "const useWebSocket", and it immediately suggested the next ten lines. Scary fast.
For the same chart component, Cursor gave me a working version in 30 seconds. But it was sloppy. No error handling. No cleanup. It assumed I'd fix it later.
Cursor excels at autocomplete. It reads your mind when you're in the zone. But ask it to reason about architecture? It shrugs. It gave me three different patterns for state management in one afternoon. I had to pick.
The Real Difference
Baichuan thinks. Cursor acts.
For complex logic—like implementing a custom event emitter with generics—Baichuan got it right on the second try. Cursor gave me something that compiled but leaked memory.
For boilerplate—like writing Zod schemas for ten API endpoints—Cursor was four times faster. Baichuan kept asking if I was sure about the field types.
Who Should Use What
If you're building a prototype or cranking out CRUD, pick Cursor. It's a speed demon.
If you're working on a production system where correctness matters more than speed, Baichuan is safer. It double-checks itself.
Verdict
I'm keeping both. Cursor for the first draft, Baichuan for the review. They cover each other's weaknesses.
But if I had to choose one? For my projects—backend-heavy, TypeScript, real-time data—I'd take Baichuan. It makes fewer stupid mistakes.
Cursor wins on raw speed. Baichuan wins on reliability. Your call.
