Llamacpp imatrix Quantizations of Qwen3.6-35B-A3B by Qwen

Using llama.cpp release b9222 for quantization.

Original model: https://huggingface.co/Qwen/Qwen3.6-35B-A3B

All quants made using imatrix option with dataset from here

Run them in your choice of tools:

• llama.cpp
• ramalama
• LM Studio
• koboldcpp
• Jan AI
• Text Generation Web UI
• LoLLMs

Note: if it's a newly supported model, you may need to wait for an update from the developers.

Prompt format

What's new:

Adding MTP layers now that support has been added with release b9180

In order to use it, run:

Embed/output weights

Some of these quants (Q3_K_XL, Q4_K_L etc) are the standard quantization method with the embeddings and output weights quantized to Q8_0 instead of what they would normally default to.

Downloading using huggingface-cli

ARM/AVX information

Previously, you would download Q4_0_4_4/4_8/8_8, and these would have their weights interleaved in memory in order to improve performance on ARM and AVX machines by loading up more data in one pass.

Now, however, there is something called "online repacking" for weights. details in this PR. If you use Q4_0 and your hardware would benefit from repacking weights, it will do it automatically on the fly.

As of llama.cpp build b4282 you will not be able to run the Q4_0_X_X files and will instead need to use Q4_0.

Additionally, if you want to get slightly better quality for , you can use IQ4_NL thanks to this PR which will also repack the weights for ARM, though only the 4_4 for now. The loading time may be slower but it will result in an overall speed incrase.

Which file should I choose?
