What problem does it solve?

This skill provides practical patterns and best practices for building, training, and managing neural networks using Flax NNX, helping teams adopt a consistent module/state-management approach.

Core Features & Use Cases

• Model Definition: Create Flax NNX modules with explicit state management and parameter handling.
• Training Patterns: Implement deterministic training loops using both automatic (nnx.jit) and functional (nnx.split/nnx.merge) approaches.
• Migration Guidance: Facilitate a smooth transition from standard Flax code to Flax NNX paradigms with minimal friction.

Quick Start

Create a small Flax NNX module, initialize it with a random number generator, and run a forward pass on dummy input to validate the training loop.
