Architecture
Standard GPT-2-small architecture:
- Layers: 12
- Hidden size: 768
- Attention heads: 12
- Maximum context: 1024
- Vocabulary size: 50257
All GPT-2 weights were initialized from scratch.
No pretrained GPT-2 model weights were used.
Tokenizer
A separate Byte-Level BPE tokenizer was trained from scratch using only the Khmer training split.
The original English GPT-2 vocabulary and BPE merge rules were not used.
Vocabulary size: 50257
