Ling-3.0-Tiny APEQ SubMini (GGUF)

This repository contains one custom GGUF quantization of inclusionAI/Ling-3.0-tiny, made for local llama.cpp inference where storage and decode speed matter.

It is an APEQ-style, per-tensor mixed-precision profile. It is not a standard uniform Q5_K quantization: the sparse MoE FFN uses Q2_K, most unchanged tensors use Q6_K/Q8_0/F32, and selected later attention tensors use Q5_K.

The file is 6,897,472 bytes (0.225%) smaller than the local Mini comparator used during this experiment.

Quick start โ€” llama.cpp

Use a recent llama.cpp build with support for the Ling / bailingmoe3 architecture.

llama-cli \
  -m Ling-3.0-Tiny-APEQ-SubMini-3.06GB.gguf \
  -ngl 99 \
  -cnv \
  --reasoning off

To start an OpenAI-compatible local server:

llama-server \
  -m Ling-3.0-Tiny-APEQ-SubMini-3.06GB.gguf \
  -ngl 99 \
  -sm none \
  -c 4096 \
  --reasoning off

The base model's native chat template is embedded in the GGUF. The original model recommends temperature=1.0, top_p=0.95, and top_k=20; use deterministic settings only when reproducing the comparison below.

Validation

This is a local comparative result, not a claim of universal quality equivalence.

The final artifact was regenerated twice from BF16 with the same exact tensor map and had the same SHA-256 each time. On a fresh, disjoint 24-case deterministic ZxBench-derived holdout, it matched the Mini comparator exactly:

Measure Mini comparator This GGUF
Holdout mean score 73.292 73.292
Cases scoring >=80 13/24 13/24
Nonterminal/empty results 3 3
V100 decode median 120.658 tok/s 131.810 tok/s
V100 fixed-512 prefill 1,846.080 tok/s 1,723.908 tok/s

Throughput was measured with llama.cpp build b10516 on a Tesla V100-SXM2-16GB, full GPU offload, no speculative decoding, and three samples of a 512-token prefill / 128-token decode workload. Hardware, context length, batching, runtime build, and sampling parameters will affect results.

The holdout used deterministic local graders adapted from ZxBench scenarios. It is a representative comparative screen, not a full hosted ZxBench run with optional AI judges or sandboxes.

Quantization profile

Tensor type Count
F32 215
Q2_K 72
Q5_K 62
Q6_K 102
Q8_0 75

The profile preserves higher precision in the early sensitive attention path and lowers standard attention tensors in blocks 5โ€“23, plus blk.4.attn_q.weight, to Q5_K. Broader reductions were screened and rejected due to measurable regressions.
