From 8f05d8d834a89594d6084a337f1950079cd70ef8 Mon Sep 17 00:00:00 2001 From: Simba Zhang Date: Sat, 15 Aug 2026 21:52:39 -0700 Subject: [PATCH] chore: extract MTP benchmark tooling from #109 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit #109 bundled a sliding-window KV cap, a Gemma4-specific MTP-assistant auto-resolution path, and this benchmark tooling into one PR. The first two are not part of this extraction: - the KV cap was independently ported and evaluated earlier this session โ€” no measurable benefit at 150 tokens or ~9k context, parked - the auto-resolution wiring (Gemma4MTPRegistry, mtpAsstRef reusing the draft-model path) duplicates what #137 already shipped more generally as the explicit --mtp-assistant-model flag; rebasing it forward would reintroduce a second, narrower implementation of a feature that already exists on main This PR is only the tooling, and it rebases clean because it is genuinely orthogonal: mtp_bench.py drives the server with --mtp --num-mtp-tokens N --turbo-kv, the single-checkpoint MTP path, not the Gemma4 dual-model wiring in conflict. Verified none of these three files reference Gemma4MTPRegistry, mtp-assistant-model, or anything else from the withheld part of #109. run_benchmark.sh's Test 13 previously shelled out to `swift run Gemma4MTPBench`, a product that no longer exists in Package.swift โ€” that path was already broken on main before this PR. It now drives mtp_bench.py against the regular SwiftLM binary instead. README's benchmark numbers (Gemma4 26B, 4-bit and 8-bit) are carried over from the original PR's measurements, not reproduced in this extraction โ€” a 40K/100K context benchmark run is multi-hour. The 8-bit table matches data already used as reference in mlx-swift-lm#46 and the #137 comment thread earlier this session, so it is not new to this repo's history, just newly landing in the README. Verified: run_benchmark.sh syntax checked, mtp_bench.py compiles and its --help output parses correctly; confirmed --mtp, --num-mtp-tokens and --turbo-kv all already exist on main independent of --mtp-assistant-model.
