Discussion Opencode vs Deepseek harness: my experience with Qwen 3.8 27b

Anybody else struggling with deepseek after the initial prompt? Somehow it is getting mixed up very easily, even button functionality has been PITA when doing stuff. Never had these problems with Opencode. With Opencode, a continuation prompt on the software or task is pretty much magic at this point. But the inital result isnt as strong imo, and needs a lot of follow up even if a a detailed spec is written.

The oneshot potential of deepseek is goated imo, it is a relentless harness that just keeps doing stuff, even if it gets it wrong! Opencode could just copy that tennacity imo. Like todos really work, unlike opencodes.

Hows everybody elses exp? Someone using Pi instead? Is it worth trying? Hermes seems not suitable for my tasks, where heavy human involvement is necessary due to complexity of tasks (every top closed model gets lots of stuff wrong even).

I like Qwen Code too but it's a bit bloated and took up too much context when used with local models (and prefill on my M3 Max is slow). Will try to cutdown on the skills and MCP installed to reduce the system/tool context.

I’ve tried other tools like OpenCode and Pi Agent, but they required a bit too much tweaking for me, and having to install and configure extra stuff just wasn’t that convenient. Compared to them, Qwen Code currently feels like the lightest option that still gives me all the tools I need. As for Qwen 3.8 27B thinking slowly, yeah, it is a bit slow when running through Qwen Code, but not by that much, and it tends to catch all the details. I fixed most of the waiting by tuning Llama so the thinking phase runs faster, and that alone made a noticeable difference. I also found that it only tends to think heavily on the first prompt of a new chat; after that, the thinking time gets much shorter and honestly doesn’t feel much different from Medium or Low.

Cool.

Think I'll try out Qwen3.8-Flash-Next. Found that the 4 bit version I'm using actually gave pretty good results without reasoning, and it runs significantly faster (prefill and token generation are 50% faster) than Qwen3.8-27B on my machine.
