DeepSeek V4 Pro Review: My Nuclear-Powered AI Programming Assistant

DeepSeek V4 Pro Is the Cheapest Nuclear-Powered Donkey At first, the way I used AI was: Ask AI to write code I manually run the program, encounter problems Ask AI to write local logs and check the logs AI writes fix code again I run again AI checks logs again 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. ...

DeepSeek V4 Pro:我的核动力驴

DeepSeek V4 Pro 就是最便宜的核动力驴 最开始我用AI的方式是: 让AI写代码 我手动运行程序,遇到问题 让AI写本地日志、查看日志 AI再写修复代码 我再运行 AI再看日志 循环往复…… 后来我告诉DeepSeek V4 Pro:你必须持续修复并解决问题,每次修复后自动运行程序,并进行自动化测试,然后关闭程序后查看运行日志,发现其中的问题;然后再次修复,再次运行,再次查看日志;直到日志中没有问题出现为止。 它听懂了。 接下来:它真的就这样一直做下去,一遍又一遍,不知疲倦。没有抱怨,没有走神,没有注意力不集中。 15分钟后,它告诉我:“日志中没有问题出现了。” 我检查了一下,真的解决了。我花费了3人民币,折合0.5美元。 便宜不、羡慕不? DeepSeek V4 Pro就是我的核动力驴。它便宜,比claude便宜太多了。 它还比较好用,只要你告诉它很明确的指令。 所以一头便宜的还比较好用的核动力驴,是不是比贵的更好一些。 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’m building in AI. Why? Because the world is full of uncertainty—staying at one company too long can make you addicted to certainty. Building in AI is like sailing into uncharted waters. ...

More on TRAE China Version: Free Models Are Great But Slow

TRAE China Version: Real Data on Free Model Speed Let me start with the conclusion: if you use the free models in TRAE China’s version, they will be slower than custom paid models (even when comparing the same model). The free models are mainly slower in 3 aspects: When processing large tasks, free models may display a prompt: “Model has reached the maximum number of thinking attempts. Please type ‘continue’ to get more results.” When this happens, you need to manually type “continue” to proceed. As shown in Figure 1. ...

Why I Use TRAE: Free LLMs, Stability, and 1M Token Context

My Main Reason for Using TRAE: Free Programming LLMs Yes — the TRAE China version lets you try multiple large models for free. As shown in the screenshot, all of these models are available at no cost for trial. Here’s the full list of free models: Doubao-Seed-2.0-Code、 Doubao-Seed-1.8、 Doubao-Seed-Code、 MiniMax-M2.7、 MiniMax-M2.5、 GLM-5.1、 GLM-5V-Turbo、 GLM-5、 DeepSeek-V4-Pro、 DeepSeek-V4-Flash、 Kimi-K2.6、 Kimi-K2.5、 Qwen3.6-Plus、 Qwen3.5-Plus、 But here’s the catch: when using these free models, you often need to wait anywhere from 1 to 10 minutes. In my experience, the average wait is around 3 minutes. But honestly — when you’re heading to bed or stepping away for a coffee, waiting 3–10 minutes is perfectly acceptable. ...

Using Qwen 3.6 Plus: Great but a Bit Expensive

I Think Qwen 3.6 Plus Has Strong Coding Capabilities, But My Costs Are Higher Than Expected I compared two approaches: 1、Using Qwen 3.6 Plus to write large-scale C# programs, then having DeepSeek v4 Pro conduct code reviews; 2、Using DeepSeek v4 Pro to write large-scale C# programs, then having Qwen 3.6 Plus conduct code reviews. I prefer the second approach for these reasons: 1、DeepSeek v4 Pro supports a context length of up to 1 million tokens. For large projects, this helps maintain clear logical connections between modules. Additionally, DeepSeek v4 Pro is currently more affordable (until May 31, 2026, it’s offered at 25% of the regular price—see screenshots in my previous blog). 2、Qwen 3.6 Plus delivers higher code quality but at a higher cost. Using it only for code reviews helps reduce overall expenses. ...

DeepSeek v4 Pro, Qwen 3.6 Plus, or Others: Which Should I Use?

i like deepseek and Qwen Before May 2026, I had never used DeepSeek, Qwen 3.6 Plus, or any other Chinese LLMs for programming. As readers of my previous blog might recall, I primarily relied on GitHub Copilot’s models, favoring Claude Sonnet 3.6 and Claude Opus 4.7 (a bit pricey—if you’re wealthy, pretend I didn’t say that). My secondary choice was GPT Codex 5.3. So when I first considered using DeepSeek or Qwen 3.6 Plus, I was skeptical—worried their code quality wouldn’t meet my standards. ...
