Laguna S 2.1 MLX benchmark
This repository contains a reproducible local harness for comparing Laguna S 2.1 MLX quantizations on Apple Silicon. Each run records the raw output and task score along with token and prefill throughput, peak MLX memory, load time, package versions, model revision, and machine metadata.
This work was sponsored by DWS LLC.
The new leader on the M5 Max is pipenetwork/Laguna-S-2.1-MLX-2bit through MLX-LM. It passed all 38 assertions, averaged 63.86 generation tok/s across the three generation tasks, and reached 68.49 tok/s in the fixed 256-token decode. It needs the conversion's bundled Laguna loader, so the harness loads that file from a pinned revision without modifying the installed MLX-LM package. The measurements are in BENCHMARK_RESULTS.md.
Results at a glance
These results were measured on a 128 GB Apple M5 Max using macOS 27.0, Python 3.13.12, MLX 0.32.0, mlx-vlm 0.6.6, and MLX-LM 0.31.3. The score combines three generation tasks and three agentic coding tasks. Throughput is weighted across the generation tasks.
The left panel reproduces the Terminal-Bench 2.1 figures in Poolside's model card. The right panel comes from this repository's committed CSV and selects the frontier plus one useful representative from each quant/runtime family; the table and CSV below contain every measured variant. The panels use separate scales and are not the same evaluation. Regenerate the SVG with:

Rows are sorted by overall score, then weighted generation throughput.
