Ling-3.0-flash-base-ROCmFP4-COHERENT-GGUF

🔧 Runtime: build the ROCmFPX fork below

Stock llama.cpp will not load this file. You need both the bailing-hybrid architecture and the ROCmFP4 tensor types in one tree. Upstream charlie12345/ROCmFPX has the ROCmFP4 types but not bailing-hybrid. Our fork has both:

kingjones30/ROCmFPX — a fork of charlie12345/ROCmFPX, branch main.

git clone https://github.com/kingjones30/ROCmFPX.git
cd ROCmFPX
cmake -B build -DGGML_HIP=ON -DGPU_TARGETS=gfx1151 -DGGML_NATIVE=ON -DCMAKE_BUILD_TYPE=Release
cmake --build build --target llama-server llama-quantize -j$(nproc)

Verified 2026-08-27 on gfx1151: clean clone → 0 build errors → llama-server loads a bailing-hybrid ROCmFP4 GGUF from this family and generates coherent text.

Ling-3.0-flash-base — ROCmFP4 for AMD Strix Halo (gfx1151)

<!-- LEAD-CLAIM:START -->

✅ the first ROCmFP4 build of Ling-3.0-flash-base, published with a measured MTP curve

Checked 2026-08-22 against every public GGUF of this checkpoint. The two other GGUF builds — mradermacher/Ling-3.0-flash-base-GGUF (Q2_K through Q5_K_S) and avar6/Ling-3.0-flash-base-gguf (Q5_K_M, uploaded 2026-08-22) — both ship standard k-quants. ROCmFP4 is a runtime tensor format that exists only in the ROCmFPX fork of llama.cpp. Repository-content comparison only — no third-party build was run or benchmarked here.

<!-- LEAD-CLAIM:END -->

A 4-bit ROCmFP4 quantisation of Ling-3.0-flash-base for AMD Ryzen AI Max+ 395 / Radeon 8060S / gfx1151, with the multi-token-prediction (MTP) draft head preserved.

⚠️ This is a base checkpoint, not an instruct model

Ling-3.0-flash-base is a pretrained / base checkpoint released by inclusionAI for continued pretraining, domain adaptation and fine-tuning. It is not instruction-tuned. It ships a chat_template.jinja, but that is a tokenizer asset — it does not make the weights conversational. Prompt it as a text continuation model. For chat, use inclusionAI/Ling-3.0-flash instead.

The file

Head protection, verified in the finished file (not merely requested at quantise time):

output.weight        Q6_K     2560 x 157184    402.4M params
token_embd.weight    Q6_K     2560 x 157184    402.4M params
histogram: ROCmFP4(type 100) x545, F32 x390, Q6_K x2, Q8_0 x1

tie_word_embeddings is false on this model, so --output-tensor-type does real work here — the COHERENT tier on its own leaves output.weight at 4-bit. Both heads were forced to Q6_K and audited on exact tensor names after the build.

Architecture notes

Ling-3.0-flash interleaves two attention types. head_count_kv is a per-layer array — [0,0,0,0,0,1,0,0,0,0,0,1,…] — where 0 marks a KDA linear-attention layer and 1 a full MLA layer: 1 MLA layer in every 6. MLA uses a compressed KV path (kv_lora_rank 512) with a plain wide query projection (q_lora_rank: null). The blk.42 MTP layer is retained in full, including nextn.eh_proj, nextn.enorm, nextn.hnorm and nextn.shared_head_norm, with the unfused attn_k_b / attn_v_b form that the MTP path requires.

Measured throughput

AMD Ryzen AI Max+ 395, Radeon 8060S (gfx1151), ROCm 7.2.4, 128 GB unified memory. llama-cli, -dio -ngl 999 -st -c 2048 -n 512 --temp 0 --seed 1234, 5 repetitions per config.

MTP is worth +15.6% on this model, with disjoint ranges and a 0.0% baseline spread across 5 repetitions.

The two sibling checkpoints measure the same baseline to the decimal on identical hardware and flags, which is the cross-check for this figure:

MTP is reliably positive across the whole Ling-3.0-flash base family. It is not reliable on Ling-3.0-tiny, where the same measurement gives +7.5% / +5.1% / −4.4% across the three checkpoints — the draft head is trained with the model, so its value belongs to the specific (size, checkpoint) pair rather than to the architecture. Measure before enabling it.

n-max 3 is the recommended setting. Deeper speculation costs prefill throughput: prompt processing measures ~90–98 t/s at n3 versus ~122–130 t/s with no drafter.

⚠️ MTP is not output-deterministic here

At --temp 0 with a fixed seed, the no-drafter arm produced byte-identical text across all 5 repetitions. Both MTP arms did not — n-max 3 produced 3 distinct outputs across 5 runs, n-max 5 produced 4, and every MTP output differed from the no-drafter output. If bit-reproducible generation matters more to you than +15.6%, run without the draft head.

Requirements

This file uses the ROCmFP4 tensor format and the bailing-hybrid architecture. It requires a build of ROCmFPX that carries both. Stock llama.cpp will not load it. Verify with strings libllama.so | grep bailing-hybrid — the architecture table lives in the shared library, not in the thin CLI binary.

llama-cli -m Ling-3.0-flash-base-Q4_0_ROCMFP4_COHERENT.gguf \
  -dio -ngl 999 -c 2048 -n 512 \
  --spec-type draft-mtp --spec-draft-ngl 999 --spec-draft-n-max 3 \
  -p "The history of mathematics begins in ancient times. One of the earliest known"

-dio (direct I/O) is recommended. At -ngl 999 the HIP backend copies offloaded tensors out of file-backed pages into device allocations, so without direct I/O the source pages and the device buffer are resident simultaneously — roughly twice the model size, which is tight on a 128 GB box.

Sample output

Continuation from "The history of mathematics begins in ancient times. One of the earliest known":

mathematical texts is the Rhind Mathematical Papyrus, which dates back to around 1650 BCE in ancient Egypt. This papyrus, named after the Scottish antiquarian Alexander Henry Rhind who purchased it in 1858, contains a collection of mathematical problems and solutions that provide insight into the mathematical knowledge of the time. The problems cover a range of topics, including arithmetic, geometry, and algebra, and demonstrate the Egyptians' practical approach to mathematics.

Not measured

Perplexity is not published for this build. No perplexity figure is quoted because none was completed on this hardware — a 127 B model at this size exceeds a practical evaluation budget on a single Strix Halo box. Quality evidence here is limited to the coherence check above and the verified tensor-level audit.

Sibling quantisations

Also built but not published: Q4_0_ROCMFP4_LEAN (72.07 GB — within 0.07% of COHERENT, since the tiers differ only in token-embedding type, which is negligible on a 127 B model), Q6_0_ROCMFPX (105.22 GB) and Q8_0_ROCMFPX (131.66 GB — exceeds the addressable memory of a 128 GB Strix Halo box).
