DeepSeek V4 Pro Is the Cheapest Nuclear-Powered Donkey

At first, the way I used AI was:

  1. Ask AI to write code
  2. I manually run the program, encounter problems
  3. Ask AI to write local logs and check the logs
  4. AI writes fix code again
  5. I run again
  6. AI checks logs again
  7. Repeat…

Then I told DeepSeek V4 Pro: you must continuously fix and solve problems, automatically run the program after each fix, do automated testing, then check the run logs after closing the program, find problems in them, then fix again, run again, check logs again—until no more problems appear in the logs.

It understood.

Then: it really just kept doing it, over and over, tirelessly. No complaining, no zoning out, no loss of focus.

After 15 minutes, it told me: “No more problems in the logs.”

I checked, and it was really fixed. It cost me 3 yuan—about $0.50. Cheap, right? Jealous?

DeepSeek V4 Pro is my nuclear-powered donkey. It’s cheap—way cheaper than Claude.

And it’s pretty good, as long as you give it clear instructions.

So a cheap, fairly good nuclear-powered donkey—isn’t that better than an expensive one?

About Me

I’ve worked at NetEase Games, Baidu, Tencent (8 years), and Meituan (nearly 7 years), leading large R&D projects and managing teams of over 100 engineers.

Now I build software as an independent developer.

Why? Because the world is full of uncertainty—staying at one company too long can make you addicted to certainty. Building on your own is like sailing into uncharted waters.

I believe good software should give people a sense of security and control. That’s the thread connecting everything I make:

  • PhotoRestore Pro — AI photo restoration that runs 100% offline on Windows. Your photos never leave your device. No cloud, no account, no compromise on privacy. Built for legal professionals, but anyone with old family photos will find it useful.

  • AstroSky — Think of it as “Snapseed for astronomy.” Turn raw FITS data into stunning celestial images. Fully offline, GPU-accelerated, with a Beauty/Science dual mode that serves both casual stargazers and researchers.

  • fastool.io — A collection of browser-based science tools. Right now it’s focused on astronomy: solar path tracking, moon phase analysis, sidereal time calculation, telescope FOV planning—all running in your browser with zero data upload.

Whether I’m gazing at the cosmos or refining a line of code, the goal is the same: build tools that put people in control of their own data.
