jax-gemini is a Python library that allows AI/ML practitioners, researchers, and domain experts to build, train, evaluate, and snapshot JAX/Flax neural network models using conversational plain English prompts without writing JAX boilerplate code.

Unlike traditional descriptive LLM wrappers, jax-gemini returns real, executable Python/JAX flax.nnx.Module objects. Your prompts dictate instructions; Gemini generates the respective code; jax-gemini runs it securely inside a sandboxed namespace and hands the resulting object back to you.

Features

• Real Objects, Not Text: Every operation yields a genuine Python object (e.g. flax.nnx.Module), trained weights, or dictionaries natively integrated with JAX environments.
• Conversational Memory: Retains the context of modifications multi-turn iteratively. Add dropout layers, reshape variables or tweak hyper-parameters step-by-step.
• Safe Execution by Default: All parsed LLM code generation is restricted through an AST Abstract Syntax Tree Validator restricting arbitrary script execution and imports.
• Auto-Healing: Encountering exceptions? jax-gemini features an adaptive auto-correction mechanism which relays failed code and Python tracebacks directly back to Gemini for automatic pipeline repair.

Quickstart

Installation

Install via PyPI:

pip install jax-gemini

Setup your Gemini API Key:

export GEMINI_API_KEY="your-api-key-here"

Conversational Model Building

import jax_gemini as jg
import numpy as np

# Note: jg automatically picks up GEMINI_API_KEY from env
jg.config.set({"model_name": "gemini-3.1-pro"})

# Build a model exclusively purely from text
model = jg.build("Build a 4-layer MLP for handwritten digit classification")

# Refine the architecture interactively
model = jg.modify("Ah, wait, add dropout with rate 0.2 between each layer for regularization")

# Train your model
X_train = np.random.randn(100, 28, 28, 1).astype(np.float32)
y_train = np.random.randint(0, 10, size=(100,))

model, metrics = jg.train(
    "Train for 10 epochs with Adam optimizer and Cross Entropy Loss",
    dataset=(X_train, y_train)
)
print(f"Accuracy: {metrics['accuracy']:.2%}")

# Checkpoint Persistence
checkpoint_path = jg.save("digit_classifier_v1")
