It starts very good but loops afterwards

Hi, here is my llama config:

-m /home/mert/Models/Qwen3.8-27B-TurboFCFusion-735-882-Here-Uncen-NEO-CODER-MAX-MTP-IQ4_XS.gguf
--mmproj /home/mert/Models/mmproj-BF16.gguf
-a qwen3.8-27
--host 0.0.0.0 --port 8080
-ngl 99 -c 150000
--cache-type-k q4_0 --cache-type-v q8_0
--flash-attn on
-b 2048 -ub 1024
-np 1
--cache-ram 4096
--temp 0.6 --min-p 0.05 --presence-penalty 0.0 --repeat-penalty 1.07 --top-p 0.95 --top-k 20
--spec-type draft-mtp
--spec-draft-n-max 3
--load-mode mlock
--metrics
--perf
--api-key-file /home/mert/.llama-api-keys
--timeout 600 \

My problem is, when it is at the beginning of conversation, it works fine, but when it starts to solve complex issues (requiring several tools calls and searches etc).
1- it starts to loop thinking and keeps repeating. (i tried to increase --repeat-penalty from 1 to 1.1, didn't resolve the issue)
2- it stops before finishing the job (like it says "i'll start doing this...", "i will have to start doing that..." but stops and i have to nudge/push it with prompts like "start" , "keep going"..."

I even used "/goal" but it still stops at some points.
I use hermes agent

With the low and without low variant, the issue persists. (I have a rtx3090 , so i could not try bigger quantizations because i don't prefer to offload to cpu)

Other than that, the model is smart and especially the less thinking is perfect for speed but these problems became annoying so i had to revert to base model (Qwen3.8-27B-UD-Q4_K_M.gguf).

Looks like I have to wait for the updated (stage2)

Hey;

Try: rep pen 1 [off] (qwens will loop with it on) ; temp .7 ; and try quant IQ4XS LOW and/or Q6 LOW.
Adjust top_k: 64
You may need to adjust caching [or remove it] ; this might be too high/too much loss for IQ4XS.
Maybe Q4KM would be better fit.

NOTE: tool calls really need Q5 (or Q6 is better) for best performance [Qwens generally speaking, all types of tool calling].

V2 ; releasing on/about Sept 10 ; may address some of these issues.

I'll wait for september 10th just to be on the safe side ๐Ÿ˜ƒ (btw, Qwen3.8-27B-UD-Q4_K_M.gguf works fine) I believe these issues will be gone on V2 hopefully.

my q6 kinda goes insanse too

i couldn't test q6 because i only have 24gb vram but i think it is best to wait for v2 for the time being

Was hoping that the Q6 LOW would work for programming, however it gets stuck after looping. I wonder if using an imatrix and something like the ymq-compiler (https://github.com/minyor/ymq-compiler) would help with making this LOW version - or just make your BF16 public. zerodigest right now makes the best programming Qwen3.8 at 19.7 GB (zerodigest/Qwen3.8-27B-YMQ-MTP-GGUF/ Qwen3.8-27B-YMQ-XL.gguf)
