This is a 12-layer decoder-only Transformer trained on the openvision dataset for 0.5 hours of wall-clock training time. The model achieves a validation bits-per-byte (val_bpb) of 4.414266 (perplexity: 21.3219) on the held-out validation set.
Data is packed into fixed-length sequences of 2048 tokens using the nanochat-compatible BPE tokenizer (16,384 vocabulary, 9 special tokens). No additional filtering or deduplication is applied beyond what is in the source dataset.
