# Boopit 1

A **27.3M**-parameter language model with a **4096** context window and native **BitNet b1.58 ternary weights** (weights in {-1, 0, 1} from step 0).

This release contains the best held-out-loss checkpoint from pretraining on [openbmb/Ultra-FineWeb-L1](https://huggingface.co/datasets/openbmb/Ultra-FineWeb-L1):

- Selected checkpoint: step **3,400**
- Tokens seen by this checkpoint: **891,289,600**
- Validation loss: **4.480278**

Training continued beyond this checkpoint, but later checkpoints did not improve held-out loss, so this best checkpoint was preserved and selected for release. The packed weights (`model.boopit`) are under 7 MB.

Architecture: 6 layers, width 512, 8 attention heads, tied embeddings, RMSNorm, GELU MLP, and a byte-level 16,384-token BPE vocabulary.
