I mostly use GLM. But I will not touch ZAI's harness with a 10 mile long pole no matter how efficiently they couple it with GLM.

Is your main concern privacy? I've been using the zcode of and on for a few months now and it's definitely improved over what it was back in the spring. I also use DeepSeek's harness. Not sure which I prefer at this point. Used to be I preferred DSH, but zcode has some features I like over DSH.

Did you miss the whole fiasco from last week?

It's why I asked if your main concern was privacy (data leakage). They open-sourced their harness this week so you can always audit it.

I seemingly did - what happened?

I just looked it up: apparently they silently uploaded your entire repo with the entire git history to the cloud. A feature not controlled by any settings, operating and retrying silently.

Their excuse was that it was a file indexing optimisation and they forgot to create a toggle or setting around it. As an apology they open sourced the harness, but wiped out the history.

It sounds to me like a good distillation technique if the project has hundreds of commits written by Claude and detailed commit descriptions. Also for completeness Grok did the exact same thing two months ago.
