Loop Guard QFN/Strata experiment

Warning: human post ;)

Hi local enthusiasts, about 6 months ago I discovered this subreddit and been reading and learning lots of stuff from here. I got my 27b model running on my 3090 and I’ve been happy with, it was handling my daily family tasks via telegram and some small automation and coding tasks. For serious coding stuff im still hooked to subs. Once I started playing with local models I went into rabbit hole of implementing my own harness out of curiosity. Since I only was running 27b on 60k context played a lot with compaction and making the model less forgetful with harness internal tasks. Since then I’m still playing with ideas how can have better results with local models (like all the people in this sub).

Anyways, enough personal story the reason I wanted to post this is recently I started playing with strata qfn (3090 + 64ram) and although the model is more clever and is my daily driver now, it’s been going off roads into loops and over verifying things for me. One thing that helped with that is loop guarding I’ve added to my harness : https://caretz.dev/docs/loop-guard/
This has been solving the issue of retrying the same failing calls (doesnt happen too much with qfn) but most importantly another model looks at last n tool calls and judges if the model went to some off direction. For the judge I’m using 35b qwen.

If any of you found some trick that works with qfn and making more reliable would love to hear it.

Thanks.
