AX-Clef-27B-MLX-AXQ-6bit

Research development artifact. Base affine6 packing with higher-precision protection, not MXFP6 or uniformly six-bit storage. No quality certificate is issued.

Property	Value
Source	Cloudflare/clef
Immutable source revision	0b331204bb13fbd2ca93a64df1956f5b55478ce5
Complete storage	26,484,659,432 bytes
Complete measured BPW	7.708893
Manifest budget class	8bit
MTP	No MTP payload is advertised.

The precision distribution and exact per-module settings are recorded in axquant_manifest.json, axquant_plan.json, and config.json. Complete BPW includes protected tensors and storage overhead. File size does not establish peak runtime memory requirements. Converted from the pinned original source with existing precision protection floors.

Observed runtime evidence

The exact runtime payload passed the following scoped check on Metal. The receipt binds its runtime input files. This is a functional smoke, not a quality benchmark, MTEB evaluation, coding evaluation, long-context test or MTP acceleration result.

Runtime	Evidence for this artifact
MLX-LM 0.32.2	Passed the task-specific smoke above
MLX-VLM	Not separately tested
AX Engine	Not tested; architecture metadata is not execution evidence
omlx	unsupported (static only)
mtplx	unsupported (static only)

Unexercised modalities and MTP behavior remain unverified. Peer runtime-specific exports require distinct variants and their own testing. See the manifest-bound static report.
