It mimics the OpenAI validation BPB protocol explicitly. +The goal of this design is to push model capacity as far as possible under the official submission artifact limit by combining: +- ternary-style projection behavior for major linear layers, +- reduced learned overhead, +- tied embeddings, +- compressed final export, +- a training setup optimized for short wall-clock execution. + +Rather than following a conventional FP16 baseline recipe, this submission explores a more aggressive compression-oriented design. + +## Key Ideas + +### 1. BitLinear Expansion +All major projections (`Q`, `K`, `V`, `O`, and MLP projections) use BitNet-style ternary-weight forward behavior. The purpose is to reduce effective storage pressure while preserving as much model width and depth as possible within the artifact budget. + +### 2. Radial Encoding +Learned positional embeddings are removed. Instead, position-dependent geometric features are injected analytically through `RadialEncoding(8)`. This reduces learned parameter overhead while retaining explicit positional structure. + +### 3. FRO Optimizer +`FRO` is a custom optimizer designed for short-horizon convergence under highly quantized weight dynamics. It replaces AdamW in this submission and is part of the experimental contribution. + +## Configuration + +- **Layers:** 12 +- **Model Dimension:** 384 +- **Attention Heads:** 6 +- **KV Heads:** 2 +- **Vocabulary Size:** 1024 +- **Approximate Parameter Count:** 15.6M + +## Artifact Accounting + +The submission script performs a post-training artifact audit using: +- counted source-code bytes from `train_gpt.py` +- compressed exported model bytes +- a final decimal-byte check against the official `16,000,000` byte submission limit + +The audit is performed after training and writes the compressed model artifact physically to disk before measuring its byte size. + +## Evaluation + +The script implements tokenizer-agnostic BPB evaluation over the official validation shard format used by the challenge. In record-track mode, the script is designed to fail explicitly if required tokenizer or dataset files are missing. + +Mock or debug behavior is only enabled when explicitly requested through environment flags. + +## Reproducibility Notes + +`train_gpt.py` is designed to: +- support distributed execution, +- run with explicit record-track failure behavior when required assets are missing, +- produce a final post-training artifact audit, +- run final validation before reporting the final result. + +## Development Status + +The result currently attached to this submission comes from a development run on non-target hardware.
