AX-DeepSeek-V4-Flash-0731-MLX-AXQ-2bit-MTP

Development / experimental AXQuant 2-bit pack of deepseek-ai/DeepSeek-V4-Flash-0731 @ 7872f01b1d1fe23eabc4c98b48bffcef5a386062.

Converted on df-macstudio-m2 (Apple M2 Ultra, 192 GB) from the native FP8 0731 source (quant_method=fp8). Product class 2bit-experimental. Recipe: AXQuant manual deepseek-v4-experimental-2bit-v0.1.yaml (uniform 2-bit trunk). MTP sidecar is packaged (mtp.safetensors).

This is not the older DeepSeek-V4-Flash Hub pack. Do not treat AX-DeepSeek-V4-Flash-MLX-AXQ-2bit-MTP certificates as evidence for this 0731 revision.

Recipe (uniform v0.1)

This is the AXQuant assignment that scored best among 2-bit-class converts on the factory v-extract suite. Later mixed / attention-6 / shared-4-bit recipes scored worse and are not this pack.

Tensors	Bits	Method
Routed experts + MLP	2	affine, group 32
Attention	4	affine, group 32
Embeddings / routers	8	affine, group 32
Norms, LM head, MTP	16	bf16

Claims

Claim	Status
Converted on Studio from the pinned 0731 revision	Yes
Official DSV4 `chat_template.jinja`	In pack
Checkpoint Tier 1 (generation viability suite)	Not certified — 7.1.5 native 15+15 combined 0.633; `v-extract` on AX Engine HEAD `80f2a3e6` combined 0.887 (floor 0.90). Distinct 2-bit recipe converts scored worse.
AX Engine 7.1.5 native load	Passed on `df-macstudio-m2` (Hub commit `cb1a34b4`, `--stream-experts off`, chat smoke `Okay.`)
Decode-128 (informational)	15.535 tok/s on 7.1.5; not a Tier 1 claim
MTP assets (`mtp.safetensors`)	Packaged — Hub name uses `-MTP`
MTP acceleration	Not certified (T1 below 0.90; MTP A/B not run)

Requires AX_ENGINE_2BIT_EXPERIMENTAL=1 for AX Engine native serve. Certificate: deepseek-v4-flash-0731-axq2-tier1.md. Comparison vs OptiQ 2-bit: optiq2-vs-axq2-v190.
