I'm using DSH with my local models (4x sparks running GLM53F, trying them on DS41F this morning). DSH is better than opencode IMO. It's a little barebones out of the box but I guess that's the point. I had to have an agent add support for attachments to make it more useful for multi-modal work.

The PTC mode is pretty nice. Feels like models are still learning how to navigate it.

I use it directly with DeepSeek models, get your key here https://api-docs.deepseek.com

That's the only key you will ever need, never goes down, no need to switch models, it has become my coding partner for life
