Introducing mlx-stump: GPU-accelerated matrix profiles for Apple Silicon, built with MLX and a STUMPY-compatible API. Find recurring patterns and anomalies in time series using your Mac’s GPU. 🧵
1/5
Repeated queries benefit too: prepared-target MASS/match calls were 4.1–5.3× faster, excluding setup.
Workload matters: STUMPY won on ordinary single-query calls, very large windows, and nearly noiseless periodic signals.
4/5
mlx-stump v0.1.1 is now on PyPI, including the latest fixes and performance improvements.
pip install mlx-stump
Requires macOS on Apple Silicon and Python 3.10+.

We are releasing an improved version of metal-graph library, 0.1.2. We've made some substantial changes to the underlying algorithms, which has resulted in significant speedups in our testing. This is still a very early experimental release, and we need to implement a lot more tests, especially under some real-world scenarios, but we feel confident that this already a very strong library that can be used for many projects where graph computations are relevant. Please go check it out. As always, feedback, critique, and any other comments are more than welcome.
Install it simply on your Mac via
python3 -m pip install --upgrade metal-graph==0.1.2

We are releasing mlx-geospatial: a Python library for fast geospatial work on Apple silicon, built on MLX. It handles point-in-polygon queries, spatial joins, distances and nearest neighbors. A few results from pre-release benchmarks on an M4 Max:

After user feedback and further optimization, mlx-geospatial 0.1.1 is out! Faster spatial joins + kNN on Apple silicon.
Warm-index component benchmarks:
M1 Ultra: 18–1,262× (median 95×)
M4 Max: 21–2,005× (median 105×)
CPU/MLX ratios, shown on the same scale.
1/4
The complete-join MLX pipeline beat GeoPandas:
M1 Ultra: 3.78–18.66×
M4 Max: 2.55–16.51×
Six synthetic workloads. Fresh indexes, exact boundaries, all matches, full GeoDataFrames + sorting. Median of 3 paired trials after warmup.
3/4
New: threaded Point extraction, faster polygon-edge searches and boundary refinement, plus chord-distance rejection for kNN.
721 tests per Mac. All 48 full-output checks passed.
pip install -U mlx-geospatial
