When I ran DS4 Q2 the other day (without the new update Q2 imatrix) it was behaving quite poorly after a few agentic turns with opencode, it couldn't modify the files it was telling me the work was ready and didn't use any tool to update files
The bugs were on the API tool call handing. The model worked well. I would retest with updated code and gguf and I and many others never saw it missing anything obvious. Reliable tool call and reasoning. The project is a few days old so certain agents / API combinations definitely had DSML related issues.
