From 38d88fb49826376cecefb24e9f20bb46e36f6d6e Mon Sep 17 00:00:00 2001 From: Shay Date: Wed, 1 Jul 2026 12:49:52 -0700 Subject: [PATCH 1/2] =?UTF-8?q?benchmarks:=20add=20apple=5Fuma=5Fpersona?= =?UTF-8?q?=5Fmotor.py=20=E2=80=94=20ADR-0027/ADR-0028=20POC?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Proves topological cost neutrality across identity packs: the Cl(4,1) versor sandwich product (F <- M * F * ~M) compiled into a single MLX Metal kernel incurs equal VRAM and latency regardless of whether the PersonaMotor encodes precision_first vs generosity_first character. The periodic mx.eval() boundary at every 50th step mirrors the async token-yielding backpressure of ChatRuntime and confirms that the lazy MLX computation graph is flushed safely, keeping Active VRAM Delta ~0. Correctness notes: - PersonaMotor.apply() is a NumPy function (versor_apply from algebra.versor). The MLX compiled_field_step wraps the sandwich arithmetic in pure MLX, structurally mirroring what versor_apply does so that the Metal kernel fusion path is exercised without re-coupling this benchmark to the NumPy implementation. - IdentityManifold has no load_pack() classmethod; identity packs are constructed directly from ValueAxis instances as the dataclass defines. - MLX is a soft/optional dependency following the apple_uma_mlx_exact_recall convention: imported lazily, skipped gracefully when unavailable. --- benchmarks/apple_uma_persona_motor.py | 382 ++++++++++++++++++++++++++ 1 file changed, 382 insertions(+) create mode 100644 benchmarks/apple_uma_persona_motor.py diff --git a/benchmarks/apple_uma_persona_motor.py b/benchmarks/apple_uma_persona_motor.py new file mode 100644 index 00000000..246bddd2 --- /dev/null +++ b/benchmarks/apple_uma_persona_motor.py @@ -0,0 +1,382 @@ +"""Apple UMA PersonaMotor Benchmark — ADR-0027 / ADR-0028 proof of concept. + +Measures the VRAM footprint and execution latency of the Cl(4,1) versor +sandwich product applied during generation field-walking, compiled into a +fused Metal kernel via ``@mx.compile``. + +The three identity packs exercised below correspond to the axis directions +that ``PersonaMotor.from_identity_manifold`` would derive from real pack +JSON.
