GLM-4.7-Flash ROCmFP4 STRIX (GGUF) — AMD Ryzen AI Max+ 395 / Strix Halo / gfx1151

First public ROCmFP4 quant of the full GLM-4.7-Flash weights for AMD Ryzen AI Max+ 395

(gfx1151 / Radeon 8060S).

The existing ROCm-flavoured GLM-4.7 quants on the Hub are all of the pruned

REAP-23B-A3B variant. This is the full 30B model, not a pruned one.

> ⚠️ Not compatible with upstream llama.cpp. Requires the

> charlie12345/ROCmFPX fork built with HIP + ROCmFP4 kernels.

Build recipe

llama-quantize \
  GLM-4.7-Flash-BF16-00001-of-00002.gguf \
  GLM-4.7-Flash-Q4_0_ROCMFP4_STRIX.gguf \
  Q4_0_ROCMFP4_STRIX

Q4_0_ROCMFP4_STRIX (type 105) is the Strix Halo attention-K/V quality recipe.

Dry-run predicted 15278.74 MiB @ 4.28 BPW and the output matched exactly.

Serving

llama-server --host 127.0.0.1 --port 8080 \
  --model GLM-4.7-Flash-Q4_0_ROCMFP4_STRIX.gguf \
  -dev ROCm0 -ngl 999 -fa on --no-mmap \
  --ctx-size 65536 --parallel 1 -b 2048 -ub 1024 -t 16 --poll 50 --jinja \
  --reasoning-format deepseek --chat-template-kwargs '{"enable_thinking":false}'

⚠️ --chat-template-kwargs '{"enable_thinking":false}' matters. With thinking on, reasoning

consumes the token budget and answers get truncated at ordinary max_tokens values. Also use the

chat endpoint — raw /completion with a bare instruction makes this model emit repetition loops.

Measured

Against the UD-Q4_K_XL GGUF of the same model on the same machine, chat endpoint, thinking off:

| | this quant | UD-Q4_K_XL |

|---|---:|---:|

| size | 14.93 GiB | 16.32 GiB |

| quality battery | 22 / 24 | 22 / 24 |

| tok/s (ROCm) | 56.1 | 48.1 |

The battery is 24 items: 8 code tasks graded by executing the generated function against

assertions, 8 long-tail factual questions, 4 multilingual, 4 maths. Both quants scored 22/24 —

parity — though they fail different items, which is sampling noise rather than quantization damage.

ngram-map-k adds roughly 1.05× on top and is worth enabling for input-grounded work

(code edits, RAG, summarisation).

Note on layout variants

Q4_0_ROCMFP4_FAST (type 103, the "single-scale speed layout") and Q4_0_ROCMFP4_FAST_COHERENT

(104) were both built and benchmarked against this one, same model, same flags, sizes within

0.1 GiB:

| layout | base | + ngram |

|---|---:|---:|

| STRIX (105) | 55.4 | 57.3 |

| FAST (103) | 53.9 | 55.0 |

| FAST_COHERENT (104) | 53.9 | 56.7 |

FAST is ~3% slower than the quality recipe despite its name, on this architecture and hardware.

STRIX is both the faster and the higher-quality choice here, which is why it is the one published.

Runtime knobs (micro-batch 512/2048, 32 threads, q8_0 KV cache, --poll 0) were all

neutral-to-negative — quantizing the KV cache changing nothing indicates the bottleneck is weight

bandwidth rather than KV.

Compiled from Hugging Face repository metadata — file sizes, shipped files, quant variant as named by each repo. No third-party build was run or benchmarked here, so this table makes no speed or quality claim about any of them. It is here so you can see the size and format options at a glance and pick what fits your hardware.
