@real_kai42: The past month has been insane. About a month ago, I made up my mind to refactor kimi-code and started designing a new architecture. I basically spent two full days in a hot spring with my laptop and portable monitor, burning through thousands of dollars in tokens to analyze, design, and verify the architecture, eventually arriving at what I believe is the optimal scheme. I think in the vibe era, architecture has become even more critical — a good architecture allows the Agent to code freely within a controlled scope without breaking things.

The past month has been insane. About a month ago, I made up my mind to refactor kimi-code and started designing a new architecture. I basically spent two full days in a hot spring with my laptop and portable monitor, burning through thousands of dollars in tokens to analyze, design, and verify the architecture, eventually arriving at what I believe is the optimal scheme. I think in the vibe era, architecture has become even more critical — a good architecture allows the Agent to code freely within a controlled scope without breaking things. - Once the architecture was finalized, we sprinted toward implementation (with countless debates and reversals along the way). - Quickly assembled a strong team — grateful for the brothers’ unconditional trust. - Rapidly onboarded the entire team — again, grateful to the brothers. - Engaged in intensive development for a stretch (when I was younger, I thought this was outdated; now I realize it’s a miracle of human engineering efficiency. You can’t imagine the iteration speed on architecture when you can pull everyone together to argue in front of a whiteboard at any moment). - Even though all the code was written in the vibe style, we still couldn’t escape the principle that “code quality is directly proportional to human attention density.” So, agents won’t replace all programmers — they’ll just make top-tier programmers 20x more productive while eliminating the rest. And collectivism >>> heroism. - We tackled problems step by step as they came up. Every day felt like the most hopeless day. - After open-sourcing, I fell ill — excess cortisol secretion affected my immune system. - What I learned this month will take me half a year to digest. - I downed an entire case of Red Bull in a week — gotta keep the biological fuel going. - Also disappeared from X for a month. Originally, I wanted to write some articles summarizing insights and ideas from the process, but I’m not good at long-form writing anyway, plus my brain’s self-protection mechanism quickly made me forget all the pain and blurred my sense of time (fun fact: it’s only been a little over a week since the refactored version of kimi-code was open-sourced, but in my emotional perception, it feels like a month has passed). Once kimi-code is iterated to a stable state, I’ll go back and summarize the lessons learned.
