🧬 Atomic Language Model

Extremely lightweight universal grammar implementation with provable recursion

A mathematically rigorous, recursively complete language model that fits in under 50kB with zero runtime dependencies. Built on Chomsky's Minimalist Grammar theory with formal verification and empirical validation.

📊 Mind-Blowing Size Comparison:

• Our Model: 0.05 MB (50 KB)
• GPT-3: 700,000 MB
• Ratio: We're 14,000,000x smaller!

Yet we still provide provable recursion, next-token prediction, and formal verification. See how we did it →

🆕 Probabilistic Language Model Extension

We've extended the atomic language model with probabilistic next-token prediction capabilities while maintaining all formal guarantees:

Features

• 🎲 Weighted Grammar Rules: Each production has learned probabilities
• 🔮 Next-Token Prediction: Monte Carlo sampling for language modeling
• 🔄 Hybrid Architecture: Combines Rust validation with Python inference
• 🌐 REST API: Flask server for easy integration
• 📦 Still Ultra-Light: <100kB total with all features

Quick Demo

# Run the probabilistic language model
cd atomic-lang-model/python
python tiny_lm.py

# Start the API server
python api_server.py

# Try the interactive demo
cd ../examples
python language_model_demo.py

Example API Usage

# Predict next token
curl localhost:5000/predict?prefix=the+student

# Generate sentences
curl localhost:5000/generate?count=5

# Validate syntax
curl -X POST localhost:5000/validate \
  -H "Content-Type: application/json" \
  -d '{"sentences": ["the student left", "student the left"]}'

This extension bridges formal grammar theory with practical NLP applications, creating the world's smallest formally verified language model.

🎯 Key Features
