ZCode – Harness for GLM-5.2 • Hacker News Board

You're referring to https://news.ycombinator.com/item?id=48751752, which was the third submission of this. The original submission was in fact to https://zcode.z.ai/en, so I took that one and re-upped it in order to have a place to merge the thread. Seemed fairest!

I'm somewhat surprised that this is not open source (from what I can tell). Compare to Mimo Code https://github.com/XiaomiMiMo/MiMo-Code (which is a CLI, while this is a desktop app).

I am not surprised it is not open source. These harnesses are hard to build - they are not just wrappers - and often they contain business logic that is not suitable for public distribution for all kinds of reasons.

Does anyone use an agnostic TUI or harness for development tasks that can fairly seamlessly switch between providers? I'm wanting local context in the spirit of "here are 3 AI providers available, for coding tasks use this one... and for writing prose use this one... and for generating images use this one..." etc.

have used both pi and opencode for the last 6 months, haven't opened a proprietary harness (cc, codex, cursor) in that same amount of time. right now i'm on pi and i can switch seamlessly between any model across any provider i want, even mid session. can even point them at locally running models. i think people don't realize how much better life is over on this side, cc and codex rely entirely on vendor lock in imo.

codex is open source https://github.com/openai/codex/ it's definitely geared towards openai but it is completely open source

Does a mid-session provider switch result in loading the entire context into the new model, inflating session cost? I don't think I understand the token/cost implications of this feature

Its nice if you used local, but needed å beefier modell, or more context Window. It will eat input tokens, but you do that all the time unless you have input caching.

UI-wise this looks a lot closer to Codex than Claude Code. It's basically an exact copy of Codex.

Which makes keeping Codex closed source look even sillier. Software is no longer anyone's moat. Just let it go.

I thought codex was open source https://github.com/openai/codex

GLM-5.2 is a great model!

But it already works really well with existing harnesses, I'm not sure why a dedicated one is needed?

I use it with https://swival.dev and everything works perfectly, no tool calling issues and it works fine with long sessions.

Peak hours are 14:00–18:00 (UTC+8) https://docs.z.ai/devpack/overview

Thanks. Those are some odd hours though, why would evening time be peak hours? Usually (in the western world anyway), 9AM - 12PM would be peak hours. Things normally slow down post-lunch, and be its slowest at close-of-business.

They're peak hours in Beijing
