This is crazy. As a heavy Claude code user, who has used over 12 billion tokens in the last few months, and never tried local coding, I finally decided to try OpenCode with the Zen plan and GLM 5.
Initially tried Kimi K2.5 but it was not good at all.
Did a test to see how far 1-2 prompts could get me with GLM 5 versus the same prompt in Claude Code.
First task, a simple dashboard inventory tracker. About equal although Claude code with opus 4.6 came out ahead.
Then I ran a harder task. Real time chat application with web socket.
Much to my surprise, GLM comes out ahead. Claude code first shot doesn’t even have working streaming. Requires a page refresh to see messages.
GLM scores way higher on my criteria.
Write detailed feedback to Claude and GLM on what to fix.
GLM still comes out better after the changes.
Am I tripping here or what? GLM better than Claude code on any task is crazy.
Does anyone here have some difficult coding tasks that can showcase the real gap between these two models or is GLM 5 just that good.
