Are Chinese Flash Models Really Faster? Overthinking, Measured in Real Sessions

2026-09-25T12:00:00+09:00

Introduction

I used to avoid any model outside OpenAI and Anthropic. But the free GLM-5.2 that Devin offered completely changed my impression of Chinese open-weight models.

GLM-5.2 finds problems fast, which makes it great for quickly producing scripts and small tools, and for rapid trial-and-error in real environments (for example, having it verify low-level webOS commands to quickly produce a skill). The craziest part: during the promo period, none of the usage counted against my quota. Insane value for money.

Background

As a developer constantly jumping across multiple projects, I frequently run into a headache-inducing issue: committing code in a company repository with my personal email, or mistakenly using my work email in a personal repo.

Recently, I made this mistake again and had already pushed it to the remote repository. This time, I decided to fix the root cause once and for all so this careless error never happens again.

From ctxd to Claude Code Connectors: There Are No Solo Heroes in the AI Era

ctxd was a small CLI tool I wrote to let Claude Code automatically pull context from Slack, GitHub PRs, Confluence, and Jira. It worked great and saved me substantial time. But a few months later, Claude Code Connectors officially absorbed 80% of its core value.

This experience led me to rethink: what is the true value of personal tooling projects in the AI era?

How ctxd Came to Life

Between late last year and early this year, I wrote three CLI tools in succession:

Exporting PR Context! Introducing the Custom CLI Tool "pr-dump"

Introduction

As a non-native speaker working in a Japanese development team, writing PR review comments is always a small challenge for me. It requires not only making technical judgments, but also expressing them accurately and appropriately in Japanese.

So I often ask AI to help write drafts, but having to manually copy and paste the PR context every time—the summary, comment threads, diff—one by one, was honestly quite tedious.
