SymbolicLight V1
This repository contains the inference-only model artifacts for SymbolicLight V1, described in arXiv:2605.21333.
The compatible model definitions, tokenizer wrappers, and minimal generation entry points are maintained in the public code repository.
Public scope
This repository contains exactly one released checkpoint for each model scale, plus its matching tokenizer:
| Model | Checkpoint | Bytes | SHA-256 |
|---|---|---|---|
| 0.8B | 0.8B/weights/pytorch/latest-inference.pt |
3,500,562,525 | 5edc3b6a6d3fb9cfaf713775133361b3ff907abf293a22ef2226785f9fbc0540 |
| 194M | 194M/weights/pytorch/symboliclight-v1-194m-inference.pt |
776,134,571 | 871dfe12d082d896dd9f5e55186f9fb7397ba7ed2b01953f8234b3e575fce521 |
The checkpoint containers retain only model tensors and configuration fields required to construct the inference graph. They do not contain optimizer or gradient-scaler state, training steps, token or data counters, best-loss values, data-loader state, training datasets, local paths, or training-result metadata.
Training, ablation, baseline, and intermediate checkpoints are not distributed. The public release supports checkpoint loading and inference reproduction; it does not claim end-to-end reproduction of training or paper metrics.
The 0.8B and 194M tokenizers are different and must not be interchanged. See
the model-specific READMEs and SHA256SUMS before loading an artifact.
