Qwen3-30B-A3B-Pollard

Qwen3-30B-A3B — Pollard

Pollard shrank this model: 61.06 GB (f16) → 7.54 GB — 88% smaller, 8.1× down.

The smallest rung here; larger, higher-fidelity rungs are listed below.

format	this model's size
f16	61.06 GB
Q8_0	~32.36 GB
Q6_K	~25.03 GB
Q4_K_M	~17.71 GB
PollardMix (this repo's IQ1_KT)	7.54 GB

Pollard builds of Qwen/Qwen3-30B-A3B made with Pollard Weights — a ladder of measured-allocation quants (bits placed by per-layer sensitivity, not a uniform crush).

Standard GGUF — runs in stock llama.cpp / ik_llama.cpp, Ollama, LM Studio. Trellis (IQ*_KT) files need ik_llama.cpp; the K-quants run anywhere.

Model details

Which file should I choose?

Every rung is the same weights, sized to a different RAM budget by the measured allocation. Pick the largest one that fits your machine with room for context:

• ~27 GB RAM / VRAM → Q6_K (25.12 GB). near-lossless
• ~18 GB RAM / VRAM → IQ4_XS (16.48 GB). recommended default
• ~15 GB RAM / VRAM → IQ3_S (13.46 GB). smaller
• ~10 GB RAM / VRAM → IQ1_KT (7.54 GB). flagship — 1-bit mixed-precision MoE trellis

The numbers (WikiText-2 raw, ctx 2048, 145 chunks; KLD vs Q6_K base)

PollardMix beats the uniform 1-bit trellis quant on every metric — PPL −4.9%, Mean KLD −14%, Median KLD −20%, top-1 +2.3 pts — at +6.9% size, under the 2-bit ceiling. Same clean sweep as the 7B/14B dense cards, now reproduced on a MoE — the automap policy generalizes (crush cold experts, protect the router / ffn_down_exps / shared experts / attention).

Download a specific file

pip install -U "huggingface_hub[cli]"
hf download PollardWeights/Qwen3-30B-A3B-Pollard \
  --include "Qwen3-30B-A3B-Pollard-IQ4_XS.gguf" --local-dir ./

How to run

These are standard GGUF and run with llama.cpp:

llama-server -hf PollardWeights/Qwen3-30B-A3B-Pollard:IQ4_XS

or from a local file:

llama-cli    -m Qwen3-30B-A3B-Pollard-IQ4_XS.gguf -ngl 99 -p "Explain why the sky is blue."
llama-server -m Qwen3-30B-A3B-Pollard-IQ4_XS.gguf -ngl 99      # OpenAI-compatible API + web UI at :8080

They also work in anything built on llama.cpp — LM Studio, koboldcpp, Jan, ramalama, Ollama (ollama run hf.co/PollardWeights/Qwen3-30B-A3B-Pollard).

ARM / AVX

llama.cpp repacks weights into an interleaved layout at load time for faster inference on ARM and AVX machines — no special file needed, online repacking covers these quants. The old Q4_0_4_4/4_8/8_8 variants are not required.

Errata

• Trellis (IQ*_KT) quants need ik_llama.cpp to build/run; K-quants run in any recent llama.cpp.
• Measured allocation places bits by per-layer sensitivity under a size budget.
• Single machine; replication invited.
