Bug: Bad tool calling performance on Qwen3.5 35B A3B (aarch64, CPU inference)

[darkgeek]

What happened?

Hi,

This is my first time to try ik_llama.cpp, it's blazingly fast! Thanks for your work!

I tried to use ik_llama.cpp to run Qwen3.5 35B A3B IQ3_XXS, on my AsahiLinux at Macbook Pro M1 laptop, it behaved not so well if it needed to do tool calling (I use pi-coding-agent):

Just like the screenshot, it might produce endless parallel tool calls quite often.

However, this issue never occurred in mainline llama.cpp with same settings (tested on 8452).

The way I built ik_llama.cpp on AsahiLinux aarch64:

$ cmake -B build -DGGML_CPU_ALL_VARIANTS=OFF -DGGML_ARCH_FLAGS="-march=native" -DBUILD_SHARED_LIBS=OFF
$ cmake --build build --config Release -j$(nproc)

My settings to run the model:

/home/justin/Applications/ik_llama.cpp/bin/llama-server --timeout 1200 --jinja --port 5813 -m /home/justin/.cache/llama.cpp/unsloth_Qwen3.5-35B-A3B-GGUF_Qwen3.5-35B-A3B-UD-IQ3_XXS.gguf -c 32768 --temp 0.7 --top-p 0.8 --top-k 20 --min-p 0.0 --presence-penalty 1.5 --repeat-penalty 1.0 --chat-template-kwargs {"enable_thinking":false}

Name and Version

$ ~/Applications/ik_llama.cpp/bin/llama-cli --version
version: 4332 (10b44ec)
built with cc (GCC) 15.2.1 20260123 (Red Hat 15.2.1-7) for aarch64-redhat-linux

What operating system are you seeing the problem on?

Linux

Might be a quant issue. Have you tried https://huggingface.co/ubergarm/Qwen3.5-35B-A3B-GGUF/resolve/main/Qwen3.5-35B-A3B-IQ4_KS.gguf?download=true ?

I didn't try this because it's too large for me. My macbook pro is 16G only😭.

As to the quant, I also tried bartowski's IQ3_XXS, but the issue remained.

@darkgeek

Does it make any difference if you specify:

 --graph-reduce-type f32

?

Secondly, I don't see any --seed parameter so its might be difficult to reproduce your behaviour.
Does the issue exists at llama.cpp mainline?

The issue doesn't exist at mainline llama.cpp (I tested on 8452 yesterday).

And I just added --graph-reduce-type f32, and retried, the issue persisted (seed was specified):

It seems like a problem with MPC server, no? It says it does not support json arguments.

Are you having some problem setting up the right chat template for the tool calling? I am not sure. Please clarify.

Well, I just use the built-in chat-template in this model, and that worked well in mainline llama.cpp. That tool write sometimes will have this issue, but that's not the main issue😄.

That tool write sometimes will have this issue, but that's not the main issue😄.

Hm ... so the main issue is that it unsuccessfully tried to edit the file with sed ?

The main issue is that the LLM returns an excessive number of unusual parallel tool calls (via the tool_calls field) during streaming completion. As a result, my coding agent has to wait for the entire tool calls list to finish. However, as shown in my screenshot, the tool calls continue to be generated endlessly until the max context size is reached.

Well, as far as i can see:

common/jinja/caps.h:

bool supports_parallel_tool_calls = true;

Actually, I am not sure how it works. Can't read the code. Have to test it, because I never used the parallel tool calls myself.

BTW, does llama.cpp is trying to call the tools in parallel? Or not? Because it seems like if more than one tool is declared, then the parallel tool calls are getting enabled huh?

Can you test #1490?
If it still has issue, add --minilog to the start up command and attach the llama.log file in your binary folder so I can look at it.

@magikRUKKOLA Seems on llama.cpp it doesn't call in parallel (maybe I need to test more).

@firecoperana I'm traveling, while my macbook is at home now, so I'll try #1490 in days. I'll give feedback as soon as possible.

Appreciate your support! Have a nice Monday!

I don't follow Asahi Linux on Apple hardware, so don't know if the GPU is supported, and from your command line arguments I cannot deduce if this is a CPU-only usage or if the inference runs on the GPU. Can you clarify? Thanks.

[darkgeek]

@ikawrakow It runs on CPU only.

On asahi, GPU can only be used via vulkan if I build llama.cpp with vulkan support enabled. But for now,
both mainline and ik versions are CPU only on my macbook.
