Start with your goals, constraints and previous results.

Prioritize changes against your goals and constraints.

Measure the outcome. Use the evidence to guide the next choice.

Remyx-assisted contributions have merged into Hugging Face PEFT, timm, and SAELens. Explore the code and maintainer reviews.

The problem

Every change competes for engineering time and compute.

01

More options than time.

Choose changes worth the time, compute and review.

02

Each evaluation takes work.

Prepare the test, resolve dependencies and gather the evidence.

03

Decisions lose context.

Keep the goal, test, result and reason for each decision.

What Remyx does

COMPLETED VALIDATE RUN

See the evidence behind one real evaluation.

After test review, Validate measured reconstruction quality and negative activations in SAELens.

Measure Baseline Change
Explained variance 0.9666 0.9677
Negative activations 0% 49.2%

Allowed explained-variance loss: 0.02. Required negative activations: at least 1%. Both criteria passed in this run.

15 min from test confirmation to results in this run. One CPU run, one seed.
