## Useful for

- Assemble a training pipeline from any dataset, flax model, and optimizer
- Set up a sweep over model architectures and layer parameters via configs
- Prototype training in Colab with runtime shape checking

## Why it’s here

- Star-counter measurements on 2026-10-27 (UTC), 16:13–18:59: 332 → 338 stars (+6). This is the change over that interval.
- Estimated end-of-day forecast: about +7 stars, using observed gains and the previous day.

## Star trust

Star growth looks organic.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

## Numbers

- Forks: 36
- Issues and pull requests: 1,572
- Watchers: 5
- Average over the last week: 2 per day
- Usual pace: 0 per day
- Stars in the last hour (measured): 1
- Latest release: v1.4.4 (2026-06-10)

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
