DeepSeek V4 Flash went crazy over a simple 500 error
I’ve been testing DeepSeek V4 Flash in OpenCode because I don’t really believe we need frontier models for most day-to-day coding work.
I gave it an old side project I hadn’t touched since around 2023ish and let it work in the background while I did my regular job, checking on it from time to time.
At some point, I noticed a 500 error and simply told it to “elaborate.”
Instead of just explaining the error, it went into a full debugging spiral. It started inspecting the Next.js proxy setup, tracing request headers, checking Docker logs, killing and restarting processes, and even writing Python scripts to inspect the network
The funniest part is that it eventually admitted it had gotten carried away and over-engineered the whole thing.
