# BitTransformerLM

## Model Details

**Model Type:** Experimental Bit-Native Transformer Language Model  
**Architecture:** Transformer with reversible layers and bit-level processing  
**Developer:** WCNEGENTROPY HOLDINGS LLC  
**Release Date:** August 2025  
**Version:** v0.1.0 (Pre-release Experimental)  
**License:** AGPLv3 (see LICENSE/ directory)  
**Contact:** [email protected]  

## Model Description

BitTransformerLM is an experimental language model that processes text at the bit level rather than using traditional token-based approaches. The architecture explores potential memory efficiency improvements through reversible transformer layers and provides built-in safety monitoring through real-time telemetry.

**⚠️ Important:** This is experimental research software requiring rigorous validation against established baselines before any production use.

### Architecture Details
- **Input Processing:** Direct binary sequence processing (0/1 bits) with parity protection
- **Attention Mechanism:** Multi-head self-attention on bit embeddings
- **Layer Design:** Reversible transformer blocks for memory efficiency (~50% memory savings)
- **Safety Features:** Built-in K/C/S (Negentropy/Complexity/Symbiosis) telemetry
- **Training Modes:** Causal autoregressive and experimental diffusion mode
- **Sequence Length:** Configurable (16-2048 tested)
- **Parameters:** Scalable architecture (tested from 793K to 771M parameters)

### Key Innovations

1. **Bit-Native Processing**: Operates directly on binary sequences with 9-bit encoding (8 data + 1 parity)
2. **Reversible Layers**: Memory-efficient computation through mathematically reversible operations
3. **Safety Telemetry**: Real-time monitoring via K/C/S metrics with configurable thresholds
4. **Progressive Scaling**: Automatic model expansion based on validation performance
5. **Dual Training Modes**: Both causal and diffusion-based training supported

## Training Data and Methodology

### Experimental Configurations Tested

**Small-scale Validation (793K parameters):**
- Dataset: 4 samples, 16 sequence length
- Training time: 0.21 seconds
- Final loss: 0.629 (converged on toy data)
- Hardware: CPU-based training

**Medium-scale Validation (771M parameters):**
- Dataset: 5 text samples with zero-padding  
- Training time: 11.47 seconds
- Loss progression: 11.84 → 5.35
- Hardware: Single NVIDIA L4 GPU (15.28 GB peak memory)

### Known Limitations

⚠️ **Critical Research Gaps:**
- **Limited Training Data**: Experiments used minimal datasets insufficient for language modeling evaluation
- **No Baseline Comparisons**: Missing comparative evaluation against standard transformers
- **Short Training Duration**: Training periods too short to establish genuine convergence
- **Scale Claims**: Some documentation overstated capabilities - largest validated model is 771M parameters

## Performance and Evaluation

### Empirical Results

**Telemetry Metrics (771M model):**
- **K (Negentropy)**: 0.0013 (information content vs random noise)
- **C (LZ Complexity)**: 0.52 (pattern compressibility proxy)
- **S (Symbiosis)**: 0.46 (alignment with reference distributions)

**Training Performance:**
- Peak memory usage: 15.28 GB (single GPU)
- Inference success: 100% on test prompts
- Convergence: Achieved on toy datasets only

## Environmental Impact

Current experimental training has minimal environmental impact due to small scale and short duration. However, larger-scale validation studies will require consideration of:
