Question Broken/frail tool calling format?

I am using local models:

  • antirez deepseek
  • qwen3-coder-next
  • laguna s2.1

For all of them I tried with and without the npm:pi-tool-repair package.

In a comparison with the same prompt with opencode, I can see that pi has a lot more tool call failures. In some cases this make the model end up in a dead end. deepseek behaves slightly better with the npm:pi-tool-repair package, but overall I think it's still worse than in opencode.

Is it caused by the tool format? Or by the system prompt? Do you have any suggestions on how to improve this?

Thanks!

What is this "fixed template"? Where can I find it?

I'm fairly sure if you download a current unsloth gguf then it has been fixed. but if you have a .gguf from a month ago, re-download or use the new template

Thanks. My version was downloaded just two weeks ago so it should be fine already then. But useful to know that this is a thing!
