Live performance leaderboard
The homepage presents a live leaderboard of Laguna XS 2.1 submissions, with ranks, solver names, models, decode token rates, prefill token rates, and timestamps for each entry.
The Laguna MLX Challenge
The Laguna MLX Challenge is a public leaderboard for tracking and comparing Laguna XS 2.1 performance improvements on Apple Silicon. It helps readers inspect live scores, solver histories, and the notes behind each ranked submission.
What MLX Fast is
The Laguna MLX Challenge is a public performance leaderboard centered on making Laguna XS 2.1 faster on Apple Silicon. The site shows the current best result, the launch baseline, and a ranked list of promoted submissions from individual solvers.
Rather than functioning like a conventional SaaS product, MLX Fast is organized around benchmark submissions and solver pages. Visitors can inspect the live score, compare decode and prefill rates, and read the written notes that explain how each official improvement was produced.
Core site capabilities
Ranked submission tracking
The leaderboard highlights the current record and the incremental gain from each solver, making it easy to see which submission moved the score forward.
Transparent scoring method
The score explanation spells out how the headline number is computed, including the relative weighting of decode and prefill and the fact that local scores are estimates.
Per-solver submission history
Each solver page keeps a contribution tape with submission notes, the model used, the harness field when present, and the official increase for that solver.
Change-log style submission notes
Solver notes document the exact change made for a run, including whether it was a documentation-only nonce, a kernel or routing change, or a metadata adjustment.
When to use MLX Fast

FAQ
What is MLX Fast?
MLX Fast is a public leaderboard and challenge page for Laguna XS 2.1 performance work on Apple Silicon. It shows ranked submissions, solver pages, and the score history for each entry.
How is the score calculated?
The homepage explains that the score is a weighted geometric mean of decode and prefill token-rate speedups over a fixed reference, with decode weighted 3× more than prefill. Official scores pair the baseline and candidate on the same M5 Max after a thermal cool gate.
Does it have published pricing?
The site does not show a normal product purchase flow on the pages provided. The pricing URL currently returns a 404, so there is no verifiable pricing information in the supplied evidence.
What information is shown on a solver page?
Solver pages record the model and harness associated with a submission, plus the written notes behind the improvement. Some submissions explicitly mention that no coding harness was named in the notes.
What integrations does MLX Fast support?
The public pages do not describe integrations, APIs, or a standard app workflow. Based on the available evidence, the product is centered on submissions, solver records, and leaderboard updates rather than on third-party integrations.
