epe-3p-smollm-1p7b-100B-20n-2048sl-960gbsz-no_bce

Converted Hugging Face base checkpoint from the Model Raising EPE pretraining run.

Details

• Architecture: LlamaForCausalLM
• Base model size: 1.7B
• Precision on disk: bfloat16
• Source Megatron checkpoint: iter_0050863
• Tokenizer: extended SmolLM2 tokenizer with 36 additional special tokens (<assistant> + 35 <charter_X.Y> tokens)
• Config vocab size: 49280 padded rows
• Tokenizer length: 49188

Variant

This is the 3p EPE variant trained without BCE constitution-prediction loss.

Chat Templates

Two named chat templates are provided:

Name	Use case
default	Standard chat format with the plain assistant role
epe	Uses <assistant> at the start of assistant turns

tok.apply_chat_template(messages, chat_template="default")
tok.apply_chat_template(messages, chat_template="epe")

Always use the bundled tokenizer; the original SmolLM2 tokenizer has only 49152 tokens and will not cover the EPE special tokens.
