+# DeepSeek-V4-Flash-0731 — ROCmFPX (uniform baseline)
+
+A ROCmFPX GGUF quantization of **DeepSeek-V4-Flash-0731**, built to run the full target
+locally on AMD Strix Halo (Ryzen AI MAX+ 395 / Radeon 8060S) in unified memory.
+
+**This is a baseline, deliberately.** The format assignment here is uniform by tensor role
+— the same public ROCmFPX recipe, applied to the new checkpoint. It exists so that our own
+adaptive-format work has an honest "before" to be measured against, on the same checkpoint,
+with the same harness. It is not the interesting artifact; it is the control.
+
+## What's in it
+
+| role | qtype | name | block | bits/weight | tensors |
+|---|---|---|---|---|---|
+| attention, dense | 101 | `Q4_0_ROCMFP4_FAST` | 17 B / 32 | 4.25 | 660 |
+| down projections | 104 | `Q3_0_ROCMFPX` | 14 B / 32 | 3.50 | 43 |
+| gate / up projections | 107 | `Q2_0_ROCMFP2` | 10 B / 32 | 2.50 | 86 |
+| passthrough (norms, embeddings, router) | — | F32 / Q6_K | — | — | 539 |
+
+1328 tensors, single file, no companion sidecar required. The qtype histogram is an exact
+match to the published preview-era ROCmFPX artifact, which is what makes it a fair control:
+the format is held fixed and only the checkpoint differs.
+
+## What it is not
+
+- **Not the Lucebox artifact.** [Lucebox's published
+  ROCMFPX GGUF](https://huggingface.co/Lucebox/DeepSeek-V4-Flash-ROCMFPX) is built from the
+  *preview* checkpoint. This is an independent build from `0731`, matching their format.
+- **Not adaptive.** No learned codebooks, no per-expert format selection. Those land in
+  separate repos.
+- **Not imatrix-calibrated.** There is no calibration input at all: the assignment is fixed
+  by role in the export plan. If you are used to seeing `quantize.imatrix.*` keys in a GGUF
+  of this family, their absence here is correct and deliberate — see below.
+
+## Metadata provenance
+
+This artifact was assembled using a metadata template taken from a published GGUF of the
+same family, and it initially inherited that file's `quantize.imatrix.*` keys — which
+described an imatrix calibration on someone else's build machine that played no part in
+producing these weights. Those keys have been removed. What remains:
+
+```
+general.name          = DeepSeek-V4-Flash-0731-ROCMFPX
+geoquant.source_model = deepseek-ai/DeepSeek-V4-Flash-0731
+geoquant.format       = ROCmFPX uniform 101/104/107
+geoquant.calibration  = none
+```
+
+If a GGUF's metadata claims a method that did not produce it, every downstream comparison
+built on it is quietly wrong. Worth checking on any quant, not just this one.
+
+## Speculative decode
+
+Pair with the drafter for DSpark speculative decode:
+**[DeepSeek-V4-Flash-0731-DSpark-Drafter-GGUF](https://huggingface.co/Geometric-AI/DeepSeek-V4-Flash-0731-DSpark-Drafter-GGUF)**
+— extracted from this checkpoint's integrated MTP head, so it is matched to this target.
+
+## Measurements
+
+**Not published here yet.** Throughput, prefill, accept rate and quality for this baseline
+and for the adaptive variants are being measured under one protocol on one box, and will be
+reported together. A number measured here and compared against a number quoted from
+somewhere else is not a comparison, so we would rather wait.
