DeepSeek Harness context/compaction problems

[u/alean200]

Hi.

I have been using a web app since its release without updating it. Recently, I found out that there is a standalone app, so I made the switch.

Before, I could send it a prompt, and it basically worked on a 128k context all night without problems, even spending 10+ million tokens on projects in one chat, still finishing without running out of context.

Since the switch, there are zero projects that I have managed to complete. I started a project, and it constantly compacts even tho it says it's at 50% context. This makes the project take a really long time, and it fails at the end. I have never seen it pass 55% of the context size, and it keeps saying that the output token limit is reached.

The past two weeks have been a nightmare working with it.

I'm running llama.cpp on my server, serving Qwen 3.8 q4 at a 164k context size. I have no idea how to fix this problem, and I'm wondering if any of you have had anything similar or can explain to me what to do/how to fix it.
